Thank you for your video....took my daughter's 2011 Jeep GC in to Jeep dealer.....they said her engine has low compression on 3 cylinders causing the problem!!! $7000+ engine replacement bill!! Can you believe that!!! Her engine runs fine once it starts....don't be taken...listen to this fella!! Thank you!!!
Well you are talking about and fixing an issue with the TIPM (Total Integrated Power Module) ......the PCM - is a different thing - (Power Control Module) ....it is the silver flat box in front of the "fuse Box" - TIPM .....the one with 3 big plugs with gazilion wires in each of them . but apart from calling it the wrong name glad it worked for you .....
Yep, thanks. I work on a ton of different makes and models and manufacturers tend to each have their own name for them. You are correct and it is extremely easy to get all that terminology mixed up. I have been turning a wrench for 20 years now and still screw it up because I no longer just work on one type of car.
WOW! You just saved my 2008 Jeep Patriot from the graveyard. I was minutes away from handing over my title to the Jeep dealer, who said the PCM is bad and they cant fix it. They contacted a junk yard who was going to give me $250 for it. I was reeling because otherwise it is a nice car with only 90,000 miles. I thought I would give this a shot first and woohoo, started right up! My fuse box is different than this one shown on the video, however. We'll see if this lasts and if other issues show up, but right now everything looks good, but now my engine light is on. Oh well. I have a running car. A million thanks!
Wow awesome i actually just looked at your site from a vid on Lack Luster and you have just helped me solve the problem with my Wrangler! Thanks for 2 lessons in one day my man, even if it is 2 years later!
@@unclemonster48 You know they will never admit it wasn't them that figured it out. If you look at the date on my video and compare it to their bulletin, you'll see they magically had a fix 5 days after my video. Coincidence?
The relay is on the inside of that control module on the bottom side. It’s soldered in you can’t see it. You have to take the control module out and take the entire thing apart in four different pieces to get to the relay solder it out soldering a new one. There was a video I found on UA-cam on how to take it apart.
No it is not. You may be talking about a different part, on this one I promise you there is no relay. If it were a relay that failed it would not energize even when power was forced to it as I am doing here. If it were a relay this solution would not work. Think about it. This is a solution that works for only this specific problem in Chrysler vehicles. It is a known problem with a service bulletin published about it.
The fuel pump relay is directly soldered to the engine fuse box circuit board aka TIPM. I had to completely disassemble the fuse box. It's in thin layers pancaked all together to make one complete fuse box. 2011 TIPM does have it soldered. Pos Jeep/Dodge Chrysler fix is cutting the bottom fuse box wires & tapping into the harness wires & installing at 50amp (large) external relay with a connected 20am mini fuse. There's also a 20am mini fuse at the mutifuse aka block fuse (+ charging/junk post) thick positive wire. It's hidden wrapped in electrical tape. Hard to see but can be felt by hand & it stick out as "wtf is that" The TIPM will shut down no matter where you're driving. DGAF. Shuts off at red lights, yields, parked, waiting for the train to pass, in a drive thru, at idling & the worst scariest is when at highway speeds will turn off. The digital guages & electronics still work (HVAC, stereo, sun/moon roof, windows, head lights all work. The analog needles (RPM, speed, coolant) drop dead. Fck you Dodge,Jeep Chrysler Mopar. A known factory problem that they don't fix other than tell owners they can buy a new TIPM for $1,500.00 programming is extra. Jeep/Chrysler, Dodge Mopar is a pos.
This is actually a recall just got my jeep done. They cut wires on bottom of TIPM and put an external relay. But now my jeep is doing exactly wat his jeep is doing. Only difference is his jeep don’t have the external relay
My 2011 Jeep Overland started having this issue today, that is what brought me here. Looking at Mopar's website it appears they issued a recall notice in 2019 for this known issue.
@spsjason2 well a technical service bulletin was released after this video. Coincidence? I don't think so because their solution is very similar, just done below the fuse box instead of on top. This quick fix can be done in the parking lot to get you home, theirs cannot.
@@dinstaar Yes, I agree your fix is great a fast solution. All I am saying is I looked the vin on mopar site and it showed a recall for the relay on November 14th 2019. NHTSA Recall Number 19V-813 FCA Recall Number V62.
@@spsjason2 Yes, no one is arguing with you on that. The original recall solution was to replace the computer. These vehicles did not originally come with a fuel pump relay and relied on computer control (a serious flaw if you ask me). The problem with replacing the computer itself is that it will also fail in time. The solution to externally wire in a relay was not published until December of 2020.
No it wasnt. The fuel pump circuit wasnt getting power. So he's feeding the fuel pump circuit with power from the cigarette outlet circuit. You dont know what you're talking about.@@Rockfordfosgate3406
Thank you for that wonderful advice. Mine is a commander 2007 3.0 CRD, crank but no start, DTC P0607 that is turning off most sensors needed to start the car. I just took turbo off and put it back after overhaul kit. Any ideas? I wonder if some ground is not coonected or there is a short circuit. Fuses all look fine from inspection
Will this fix issue on 2019 Renegade? 2.4 L multi-air. Happened once and finally started and ran fine for 2 weeks, and threw a code p0069 pcm replacement after I finally got it started. Happened a 2nd time and it won’t start
Thank you. I actually saw where I had the recall work done on the fuel pump. Problem on the skim issue is thst everyone says I need to send the ECM to someone to delete the SKIM but I cannot take it out and cannot find anyone to do it for me. I’m sure the dealer won’t do it.
You are UA-cam instruction God. Clear. Concise.easy to follow. I even found a test light to use. Truly hoping this will fix it!! Stuck in Paduca KY. Omw to GA from Chicago.
Thank you for the helpful video and for addressing every inquiry! I’ve just subscribed to your channel. I have a 2010 Jeep Compass with a functioning battery, but the engine isn't cranking. I checked the fuses and found no voltage in the Engine ASD relay feed 2 & 3 (no. 23 & 26, both 15 amp). My fuse no. 13 is a lighter fuse (20 amp yellow). Can I use a fuse tap to connect a 20 amp fuse on one side and a 15 amp fuse on the other side? Also, which fuse port should I use, no. 23 (ignition) or 26 (fuel injector) ? Please & Thank you!
@@MOHITSHARMA-kj3cw isn't cranking or isn't starting? If it is turning over and won't fire, use this solution. If it is not turning over at all, check your starter.
It wasn’t the starter but the ASD relay causing the issue. Jeeps have a known design flaw with this relay, leading to corrosion and starting problems. I cleaned the relay and reconnected the wires, and it started right up. Thanks for your response though! I’ll definitely keep following your videos for more helpful tips.
@@MOHITSHARMA-kj3cw that is great. I was trying to fish for some more information with the question isn't starting or isn't turning over at all. Yeah, a bad relay is a common problem that will not allow power to go to the starter. Glad you got it.
I appreciate you very much sir letting us all know about this information . A year ago my 2005 JGC security went off when I put key in door and it shut the fuel pump off I searched it here on UA-cam and found this video it worked 💯 so I am Thankful sir! I’ve run Jeep this way since but it done it again so my question is Now What? I got fuse tap’s just like you have but now it’s done it again what can I do to bypass it.
@@dinstaar yes I am I was 75 miles from home when it shut fuel pump off. So I ran a hot wire from fuse box under dash to positive wire on pump and I put it on a switch on dash so I can cut power when I cut engine off. So now I’m home the door locks and power windows and of course the fuel pump doesn’t work. So I’m guessing it’s the TIPM or PCM it’s something that’s stopping power from these components. But I got it home and I have 1,500$ in it been driving it for a year and a half so if I can personally fix it I will but I want be paying anyone to fix it.
@@williewaynewheelbarrowtoma4436 did you protect this new hot wire with a fuse? How many amps was it running? The reason I ask is because you may have pushed too many amps to your PCM causing damage. We already know your PCM is damaged because of the original failure. You can order one and put it in yourself. It is not too difficult. However, by grabbing a random wire under the dash you may have caused more damage. I would start with a PCM and see where you stand after that.
@@dinstaar I want to Update you about my 05 Jeep Grand Cherokee 3.7 Idk how long it will last again this time but like I said previously got it home had to run 45 Top speed because not only did it shut fuel pump off but this time Transmission wouldn’t shift into high gear along with the windows wouldn’t work also the stereo didn’t work that’s the first time it’s done all that the past 2 times security has just shut off the fuel pump. Here’s what I did to make it work again after I got home. Took the the Tipm completely out of car along with the Flat Thing mounted to the side of Tipm I’m guessing it’s the Computer are it maybe part of the Tipm either way I left it mounted to the side of Tipm but I Took these things in the house . It was terribly Cold. So next day I took my Big magnifying Glass and pocket knife got some Brake cleaner got it under a good Light so I could see well and I found that a few pins were a greenish color so I scraped those and one of the Plugs that plugs in bottom of Tipm has either been partially eaten away by battery acid or something got hot the pins were all there and complete some of the Plastic housing was gone and exposing A few pins. Wasn’t in need of going anywhere for a couple of days so I kept Tipm in house When I put it back on Jeep and connected plugs I coated the side of Tipm plug where it was damaged and let it dry good and next day when I connected battery I heard fuel pump start pumping. It started right up and windows were working stereo came on and transmission shifted correctly so it’s few weeks now and so far so good.
After replacing the fuel pump/3.7 WK- Im now having a problem with a vapor lock and my new pump is making a ringing/humming noise off and on-is there a way to fix it with a inline check valve or inline filter of some sort. I have to release pressure on the fuel rail to re-crank it after it runs for more than 20 minutes/ which is a possible fire risk.
hello mr..i did it before...but its better to join a relay 30amp by connecting a real circuit with the dark blue orange wire below the box under the m25 fuse anyway i like the piece you used its a simple way at least to move the car
No one is going to pull the entire box out when they are stuck somewhere, or even just in their driveway. Your way may look more tidy but sounds like a lot of unnecessary work to get down the road. Thanks for your version and opinion though. Where is your video?
There is one issue... The PCM still needs to control the fuel pump relay. The fuel pump is ONLY supposed to run during crank and while the engine is running. NOT while they key is set to accessory or run. If you are involved in a collision where the engine stops but the fuel pump continues to run, if a fuel leak is created by the collision, then you will squirt fuel continuously and risk substantial fire.
Hi. Great comprehensive vid. Thank you for taking your time. My key light (key with a line across it) is showing and so it is most probably due to either the key, skim or the PCM unit. Will bypassing the fuse like you did help solve my problem? Your kind advice will be much appreciated.
@@bearclaire6894 My issue took forever to figure out. Until the mechanic found that its the AC unit that was faulty and so somehow affected the electronics causing the key light to turn on (and engine to shut down randomly). I changed pretty much everything else but only until I replaced my AC unit was the problem solved. The mechanic said he was sure it was the door lock switch panel that may have caused the issue but turns out replacing that didn't help. Yours might be caused by a different issue. But I hope this info helps as nobody seems to think a faulty AC unit (the unit in your dashboard) could've affected something so unrelated. Good luck!
Do you remember what exactly they changed? I have the same issue. My heater core went out and soon had that red flashing key on the dash which prevented the vehicle from starting. Thanks for any info.
Hi. I have 2002 grand Cherokee overland. Yesterday it stalled like it was starved for fuel. After sitting for a bit it will start and run for a few seconds. I think I have it narrowed down to the skim and or pcm. Does this bypass the skim as well as the pcm. The light on the dash that shows a key with a line through it comes on.
Your computer system is different on an 02. No promises it works. I don't know what you are referring to about a "skim". Sitting for a bit and then working is typically contaminated fuel by the way. The reason it works is you are giving all the contaminants a chance to settle. When you stir them up and mix them into the rest of the gas a problem exisits.
@@dinstaar the skim is the black ring around the ignition that reads the chip in the key. It sends a signal to the pcm only providing power to the fuel pump for 3 seconds and then shuts it off. Security feature. Seems to be a constant issue from99-04. Most videos have the pcm “wiped” and the skim removed as not to reprogram to that specific key. In your opinion, opinion only, would testing your technique cause further damage?
@@kevinkelly3456 ok, now I know what you are saying. I have honestly never dealth with that specific issue. I can promise you though that wiping a computer is easy, getting it back to correct perameters can be a challenge. Be prepared to send it off for reprogramming if necessary.
It would be an unrelated issue. Is your speedo just not reading Amy speed at all? The most common issue for that is a speed sensor toward the rear of your transmission.
Hello from San Antonio, my son tried to start my 99 JGC but he didn't have the alarm remote and the alarm went off and he tried to turn it off by turning the key. But it wouldn't turn off until he got the remote from inside. Now the jeep cranks over but will not start. It sounds like it wants to but nothing, I've even tried starting fluid. Do you have any advice, I can't afford to take it to a shop at the moment. I would really appreciate any advice you can offer.
please help. My 2012 jgc 6 cylinder is having starting issue. I drove to dealer when it started and code read “ECM miscommunication with SKI M.” Is this the same issue? What is the service bulletin you refer to?

Would this be the same for a 06 commander? Having the same issue. I believe the anti theft system is shutting down the fuel pump. When I reprogram the key it works but then stops working. I did have a pcm code but it went away somehow. Any advice would be appreciated
I have a 97 Cherokee and I just got a new pcm and it wouldn’t start and so I ran a bypass in my add relay for months and drove it that way. I didn’t realize that there was possibly a skim immobilized problem . The I’m has the skim removed but I can’t find the immobilized on the vehicle and I’m at a crank no start again and this is my every day … any ideas?
Hi. Thanks for the video. My Jeep seems to be a little different. My fuse box has the following markings: HOLP SW / blower, cooling fan, battery acc, ign run-start, IGN ACC/RUN, starter hbl, ac clutch. That I need to use ign acc/run seems clear from your video. But what is the other one? I can't find number next to the fuses, so that didn't help.
You either have an older or a newer jeep if your box is different. Therefore you have a different PCM and and this is likely not your solution. Keep troubleshooting.
@@dinstaar thanks for responding. Mine is a 1997 4.0 Cherokee. It sucks that there are so many differences between Cherokees. Some other solitions offered on UA-cam also didn't pan out and were probably for a different model/year. I'm starting to lose faith in finding something that will work.
@@rtv9_noord Troubleshooting is the most difficult part. Why do you think we charge so much? Because it isn't easy. Most of the best techs go to an expensive tech school, then get several OEM and engine certifications, then have to gain years of experience in our field to be considered any good. Sorry but it is really impossible for me to help you without having your jeep here to see it, hear it, and feel it. Good luck.
@@dinstaar Thanks for your respons. I wish there was an expert nearby, but there doesn't seem to be. I asked around. I thought the problem is simple: the remote doesn't work. So diagnostics are limited to whether the key fob is defective, the receiver, or the system that manages the signal and cuts the fuel supply. I had hoped that circumventing the security system would be something I can do myself since shops here abouts have to do the same thing I'm doing: surf the internet, ask around and just try stuff that is presented here on UA-cam. Two down, three to go.
@@rtv9_noord so everything works but the remote start? Is this an aftermarket system? To be clear what I am doing in this video does not bypass security in any way. It bypasses a known problem in the PCM that fails to provide power to the fuel pump. Let me know if everything works besides the remote start.

have a 2013 cherokee 5.7 had the recall repair done that supposedly fixed the hard crank no start behavior. Did not fix it. Every now and then it will pull the violent crank no start behavior. Then it will start. Jeep is no help on this. Will this hack you came up with solve my issue? Thanks
WOW , before you all start blaming this guy for it not working why not check if you have fuel pressure at the fuel rail ? "MY CAR WONT START " really ? do you have spark? fuel pressure ? and the big one (Yes i have been called out many time to find NO FUEL IN THE TANK ) Great vid mate Rob NSW Australia
Thanks for watching and paying attention. I am pretty clear that this is the solution for a specific problem but some viewera don't catch that. You are 100% correct that in order to know if this will fix your Chrysler PCM problem troubleshooting must be done first. This is not a magic solution to fix every problem on a vehicle.
@DINSTAAR I ordered a PCM but I intend to try your solution first on my 2011 Jeep Liberty. Its starts and keeps running only when the gas is held down (but runs rough), stalls out when released. The starter also runs on after the vehicle is started. My mechanic said I needed a PCM after replacing a few coils and the issue did not go away. They tell me that the cylinders were not communicating with each other and some cylinders don't display proper compression. They also said it was not a mechanical problem. They never mentioned the fuel pump not working properly. Please let me know if this sounds like your solution would work. I understand you can't give me a definitive answer but a percent chance would be nice.
This solution will absolutely not fix your issue. Your PCM is malfunctioning on several levels and needs replaced. This only addresses the common PCM failure of powering the fuel pump. If your Jeep starts, this is not for you.
@@kurtengel6029on mine, It wasn't anything to do with the computer. It was in the cylinder but they wanted 4k to fix it so I bought a renegade and got 400 for the dead car on trade in
Hey buddy quick question if I change the computer in the car for other reasons.. Will this get rid of the security part of my computer so I can just turn the thing on I'm going to try a junkyard computer hoping your hac will bypass security
His hack is specific to fuel pump failure due to a known issue with the PCM. It has nothing to do with security. I am not sure how Jeep disables for a key programming issue but I believe the starter will not turn over. If I am correct this bypass will not work and neither will a new PCM. Sorry man.
Bro I'm having the same problem right now ,JGC 2012 will crack but will start can you tell me what to get from the store and explain how to fix the problem
Was this done after the recall in which an external fuel pump relay was installed to bypass the tipm? I'm getting p0628 code, crank but no start in my 2012 grand Cherokee 3.0 crd
This bypass was done before the recall. I figured this out myself, Chrysler could not. Their recall solution is a modified version of this they took credit for, they just added a relay where I rely on a fuse. Check the date of my video, 5 days BEFORE they published their bypass.
@@dinstaar Thanks for the response, I thought I narrowed down my issue to the recall wiring being faulty, after cutting out the joins the dealership put in and putting in fresh crimps the problem is not resolved. The next area I plan to look at is the pink control wire, since during the recall process they pop the pin out of the harness plug, it might not be seated in properly and isn't making a solid connection to the tipm. If this fails to fix my issue I think I will try reversing the recall, remove the relay and try your pcm bypass solution. I'm not convinced it's a fuel pump issue just yet.
@@bloggs24 If you do the electrical checks for voltage I show in this video, you will know if it is a fuel pump issue or not. Do not skip that step, it is the most important part.
Hey I don't see a lift pump fuse on my 06 Grand Cherokee where would it be located??? I really don't want to pay all this money to get it fixed in a shop
If yours is an 06, you have a different problem and a different PCM. This won't work. Tell me your symptoms and I will attempt to point you in the right direction.
Has anyone ever done this fuse tap trick on a Jeep Commander?? They only made them from 06’-10’. And I have a 06’ and the fuse box is way different and I can’t figure it out I bought all the fuse taps and stuff for $30 and will be towing it to the dealership for a $900 TIPM replacement today if I can’t figure out how to fix it.
Your fuse box is very different than those made from 2011 to 2022. This is a specific solution for a very specific problem and that is all it is. Depending on your model or anti-theft equipment your solution is going to be very different.
Im working on an 02 Grand Cherokee 4.0. I believe the Skim system has failed.No fuel.I installed a new mopar fuel pump and filter.Still no fuel. The key light on the dash stays on and I also cant get my scanner to link up with the ECU.Wierd. Im wondering if this trick would work to be able to bypass the Skim system.
This is a very specific bypass for a very specific failure. It is not a fix all for any problem. You seem to have a damaged PCM or a skim issue. That is very different. Good luck.
It really could be a few things. I don't have your jeep in front of so I can only try and tell you to check a couple things. First, does it only happen if you have parked it for awhile? If so it is likely you are losing prime. Cycle the key on, wait about 30 seconds, then start. This will prime your line. Second, do the electrical checks I show you in this video. Your PCM issue may have started. Key on and see if you have power where I tell you to look in the video. If you do not, do this bypass. If you do, you have a priming issue.
@dinstaar if it's losing prime, would it more likely be a fuel pump issue or a vapor lock issue. I'm leaning fuel pump, but would like your opinion. No visible fuel leaks, currently.
@@brianchambers6225 Troubleshooting this issue over UA-cam comments is impossible. Sorry. I would need the vehicle in front of me and a lot more information. If you are near Waco, TX swing it on by and I'll take a look.😀 Most commonly this could be your fuel pump, fuel filter, a cracked or loose line somewhere, or contaminated fuel.
Will this work on a 06 Jeep Commander 4.7l V8? Shop said I need to go to the dealer to get the TIPM replaced and the new one must be programmed by the dealer. Cost $900
Tim, without your Commander here in front of me I cannot troubleshoot it. If you Jeep will not start because your PCM is not sending power to your fuel pump, this is the fix.
It does not affect the PCM at all. The PCM is bypassed and is no longer in control of your fuel pump. Your PCM is broken, that is the problem. This fix is PERMANENT. The PCM has a known issue of failing in this manner only. Besides not providing power to your fuel pump, everything else works fine. You can replace the PCM if you like, but it will fail again this same way. It is a known PCM flaw. Many people have replaced their PCM to have the same problem down the road.
Hey I have a 2012 grand Cherokee, installed a new battery, starter, fuel pump relay kit, fuel pump is working (checked with a jump wire on 87-30) same test on the starter relay.... this fuse wire didn't work. Checked all relays and fues' Starter still spins but doesn't crank, will crank for a second randomly Is it time for a new pcm?
I need a better description of "starter still spins but doesn't crank, will crank for a second randomly." Are you saying the starter is turning on command but the engine will not turn over? Or are you saying it is not cranking long enough? Please clarify. Also, you cannot check to see if your fuel pump is working with a jumper wire. So please tell me what you did here. You can check your fuel pump by checking power at the pump, or cracking a line and seeing if fuel is coming out to the engine.
So it spins but doesn't engage with the engine. Randomly it will catch and try to start, have got it to actually start twice. I have put a jump wire on the 87-30 in the fuel pump relay and I do hear the pump working
@@5K7WLKR your starter is not engaging with your flywheel. You will have to pull it out and bench check it. Make sure your pinion is pushing out your gear so it can engage. Your problem is that the gear on the starter is not turning your flywheel. Could be your Bendix, solenoid, or a bad electrical connection. Best way to check it is to pull it out and put 12 volts straight to it and see what happens. Be safe. You better hope it is your starter because if it is the gears on the flywheel it is not a small job.
My friends 2009 Jeep Grand Cherokee with a 3.7 will not start. It will randomly start sometimes when we try but it’s not having any engine codes. It will start sometimes and we replaced the fuel relay fuse and it ran for a week then wouldn’t start again, it started back up and it’s a constant pain to try and find the problem . Suggestions?
I suggest you take it to a mechanic who is very good at electrical issues. There could be a ton of different things causing this issue. If you are in the Waco area let me know.
I have a 2012 jeep liberty after running for a day fuse 28 blows . If the engine is hot it will keep blowing the fuse once it cools down I relace the fuse and will run but same happens after a while. Will this work in my situation ?
Of course not!!! The fact that you would even consider any relation between this video and your problem tells me you should not be working on your Jeep yourself. Find a local shop and take it there.
Hey boss, ive got a 2012 jeep grand cherokee 5.7 swapped fuel pump, spark plugs, fuel injectors are showing charge, gave the car a new battery replaced fuzes and relays tried this bypass and even swapped my position sensors, car still only cranks, and clue what the problem is
@@jadenfox3445 you did not mention air flow or any check engine lights. Check for air restrictions, look for a fault code that could be related to the computer cutting fuel. You could also crack a fuel line and see if gas is getting to your engine. Good luck.
Great idea in a emergency but fuel pump is live with the key in the run position. What if the person gets in a front end crash and springs a fuel leak. Pump is still pumping gas and the operator is unable turn the key off . Need I say more!
This how is was always done before. Plus, this would still happen anyway. Your fuel pump is turned on by the PCM the minute you turn the key. They simply use the PCM instead of a relay now. It is not any more dangerous by running your vehicle this way. Great question. Thanks.
I have a 06 Jeep commander 4.7L V8. They said that my TIPM NEEDS REPLACEMENT. Will doing your fuse tab trick fix my car they said it’s not getting power to the fuel pump

@@timland7553 I need an electrical schematic. A picture of your fuse box would tell me nothing. Put one long lead of a multimeter to your fuel pump (where you should be getting power on key on). Do a continuity check at your fuse box to see which fuse beeps. That will be your fuse my friend.
I have a problem with my Jeep g ch 2011 and suddenly on the road a burning smell came out of it. I replaced the battery, fuse box, ECM PCM control model, and also replaced the alternator, and there is still something that is damaging all of these things and the car stops again and a burning smell comes out of the alternator and a clicking sound from the tipm. I really do not understand what the problem is. I have paid $2,500 so far.
@sultanalwah8286 stop randomly replacing components immediately. It is a fast way to lose money. If it is a burning smell , it is likely your belt. Inspect it for damage, then check all your pulleys. I'll bet you find something.

No check engine codes. Do you think this is the same issue? Should I be proactive and do this? My fuse box is properly listing the fuse as a Fuel Pump Motor 20 Amp :).
This failure has no check engine codes. How long have you had this issue? This is not a known issue for a 2018. I am not saying it is impossible, just not likely.
Hey Henry I’m having that same problem today man I been on the side of the road for hours cause it actually ain’t starting up this time, did you solve your problem? I’m in a 2018 Jeep Grand Cherokee latitude
I’m having similar issue in my go cart 2019 renegade 2.4L. Mine started after 2 days and threw cod p0069. Most likely solution pcm replace and reprogram. Waiting for a tow this time to dealership, unfortunately. Any ideas would be nice since I’m 3 months past my 3 year warranty. 30,000 miles. I’m absolutely disgusted and shouldn’t have to deal with this $hit.
@@dinstaar I have a Town and Country minivan and my alternator stopped working I replace alternator but still not working I want to bypass PCM / computer because I just need the battery to charge. I have an external voltage regulator and I can get power from fuse box that turns on when the key is on. It should work but it's not Alternator is new and checked and voltage regulator is new too. But still not charging I am missing something, but I don't know what. Can you help me? I will generously make a donation to you. Thanks
@@marcodeluca4068 It is impossible to diagnose this over yahoo comments. However, I can tell you that your PCM has absolutely nothing to do with it. Your alternator is directly connected to your battery. Look at your wires and battery terminals. Look for broken wires, corrosion, a loose connection, or a bad ground. Also, test the alternator directly at its connections for voltage between 13 and 14 volts. Test the battery too, it may be bad. Follow these directions and you will find the cause of your problem.
@@marcodeluca4068 Modern alternators have regulators on them. You should not have to connect it to an external one. What is your voltage at the alternator? Jump the van and connect your multimeter to the posts on it and see. You should get 13 to 14.5 volts. If you don't, your brand new alternator is bad. If you have good voltage, check your connections and make sure they are tight ND not corroded. Follow the wires from the alternator and look for breaks.
Hi Mr. DinStaar. I have a 2016 JGC Laredo. While driving i lost all power while at a red light. Had to get jeep towed. Had alternator, battery, starter, and auxiliary battery checked and all is great. When i have been able to start jeep all dash lights and gear lights blink continuously before jeep shuts back off. And sometimes it just on its on continues to start but want turn completely over. Can you share some wisdom with a young buck ( 19yr old ) to help me get my baby back running
Any mechanic who is honest with you will tell you a diagnosis should be done in person. Anything else is a guess as it could be literally hundreds of things causing your issues. Your issue could be as simple as a bad ground, loose battery cable, PCM, fuse panel, etc... Without the vehicle in front of me where I can touch it, see it, and hear it I simply don't have enough information to tell you what is going on. If you are in the Waco, Texas area I could help you figure it out.
@@skylimits313who9 When you say "lost all power" please be specific. Do you mean your engine died? Or no electrical function like nothing on your dash worked as well as windows and lights? The fuse you are checking is it the fuel pump fuse I mention on the video? Is your key on? Do you have power at other fuses? I would help you out if you were anywhere near me. You are more than 100 miles away. You would not want to pay that bill man.
@@dinstaar My engine died first. Then my dash lights started flashing uncontrollably and they too died. Jeep wasnt getting any type of power. Lights want come on, windows wont operate, couldn't shift to neutral either. Tried getting a boost and that didnt work. At first i wasnt getting power to any fuses until i hooked negative cable up to ground inside fuse box and positive on regular positive terminal. Then i hooked cables other end to my girlfriend's car. I then tested all fuses and found that the pcm fuse has no power along with the AC Clutch
My jeep cherokee laredo 04 won't start it makes a click sound every time I try. the radio works lights everything besides the not starting part had a jump charged up the battery and swapped out the starter but still nothing wondering if you have a idea what it could be would appreciate it.
It could be easy to figure out. Swing it by my place in Waco and I'll take a look. Lol. A good mechanic will he honest and tell you, to do it right I need to see it, touch it, and hear it in person. It is most likely one of 3 things. 1. The battery. Make sure you have 12 volts and load test it. 2. The starter. Jump the electrical contacts and see of it turns over after you check the battery. 3. The starter relay. It could be something else but those are the top 3 culprits. Good luck.
Hello! I have been having a similar issue but not exactly the same. On my 2012 JGC, it will crank and start but imediately stall. Second start it will crank until it times out. Third start it starts fine and stays running. Any ideas?
Any honest mechanic with experience will tell you that without the vehicle in front me I would be guessing. It could be a large number of things. Any chance you are in the Waco area?
Is this the same for a 2012 jeep Compas but my wife doesn’t have a cigarette lighter is the fuse still there cause that’s exactly what her car is doing it cranks Kranks Kranks a new start
Open your fuse box and look. If yours is the same as the one on this video, it will have that fuse there. If the fuse is missing (because it does not have a lighter), you may have to stick a fuse in it.
I cover that extremely clearly. I literally show you as I am working, while telling you how to do it. Then again I say it at the end of the video with the numbers of the fuses and the description of what they are for. If you can't follow that, I don't know what to tell you.
If you watch the begining again, you'll see I diagnose that there is no power getting to the fuel pump at all. The PCM is not sending power to that circuit. That is why there is no power to that fuse. This is a common issue for all vehicles Chrysler uses this computer in. The particular Jeep in the video is a WK2 (2011 through 2013). Look for this specific failure in many Chrysler products using this PCM.
2012 Jeep Grand Cherokee. I had high hopes for this solution but sadly it didn't fix my problem. I guess I'm faced with having the car towed to a dealership, where there's a two week wait for the new PCM and installation, if that is indeed the problem. A local mechanic thinks it could also be the fuel pump itself. Either way, I'm out around $1000 for this.
You will know for sure if it is the problem by doing checking voltage exactly like I did to see if the fuel pump is getting power when the key is switched on. If the results you get are like on my video, it is the PCM. If you jump with fuse taps like I show you, then power is getting sent to your fuel pump. Have you cracked a fuel line to see if fuel is getting pumped to your engine? Have you checked for power at the fuel pump itself? There my be a broken wire.
@@dinstaar I checked the power with my voltmeter at M25 (labeled "FUEL/DSL LIFT PUMP" like you said) and zero volts. Jumpered to M7 which showed 12.5V on the meter. Once jumpered, I saw 12.5V at M25 but no start. Could it be I have a combination bad PCM and fuel pump? For what it's worth, we run this car almost exclusively on E85 ethanol, popular in our area. (Yes, it's a Flex Fuel engine!)
@@zumajim Well E85 is garbage. It is alcohol, not gas so it has no lubricant in it and is very rough on everything it touches because of that fact. When you factor in worse gas mileage you'll find that in the end it costs you much more than gasoline because of the added maintenance and repair that you have to do when running it. Your likely causes now are a loss of prime, a broken wire going to your fuel pump, a cracked line, a bad fuel pump, or a clogged fuel filter. Start by cycling the key on and off several times letting the fuel pump run for awhile each time. If your lines are dry, you need to give them a chance to fill up and build pressure. If that doesn't work, open a fuel line near the engine to see if you get fuel coming up there. If you don't time to check the fuel tank where the filter and pump are. Good luck.
@@dinstaar Hey just wanted to report that my car started after all with your jumper fix! A different post mentioned "cycling between ACC and RUN a few times befor engaging starter" and that helped, I think. Either way, she now starts reliably and we cancelled our appointment with the dreaded dealership (which is still almost two weeks away... That was the best they can do!) So add me to the long list of very happy followers. Can't thank you enough, sir!
I’ve got a 2012 Jeep jk. Code u0100 no communication to pcm ecm (A). No start, would this bypass start my Jeep haven’t tried it but when shops open will definitely give it a go.
This is specifically for the problem of the jeep turning over but not starting. It is for when the PCM has failed to send power to the fuel pump. You may have a different issue but good troubleshooting is not possible when I am not in front of the vehicle. Are you in the Waco, TX area?
2004 grand Cherokee has a problem with hard starting. Change the fuel filter first couple times it started right up now it takes three attempts burned out the starter new starter. Started right up couple times now we’re back to three attempts before it starts. What could be the problem
i have a 2015 JGC and it's having issues keeping the battery charged. It will click once when I push to start, or when charged it might turn over once or twice. When hooked up to the bigger battery charger it was warm and turned on immediately. Now sitting on the small battery charger for a whole day it will only turn over once or twice, then click, nothing. Any ideas?
You have the symptoms of a bad battery my friend. As a battery ages it will charge but either not hold it, or lose cranking amps. Sometimes they even show 12 volts but fall flat as soon as you put a load on it. You need voltage and amps to turn that engine over. Clicking noises is almost always a starter solenoid attempting to engage but cannot because of low power. You can remove your battery and take it into any auto parts store to have it tested. However, be prepared to buy one when you're there.
Look at your fuse box and you tell me. There is a map printed right on it. I don't have a Compass in my driveway to check. If the fuses I point out are the same as yours, do the voltage checks I do. If your results are the same it will work.
Was the car turning on after a few tries or just not turning at al i have a 2013 wrangler when cold it turns on ok After running and parking and turning off for about 20 min it will have it just crank and later turn on
Mine started off that way and then would only turn over and start again. My theory for you is that the PCM electrical contact may be intermittent. Meaning the contact is separating and is weak but may not have lost all contact yet. When cold the electrical connection has not been vibrated apart, after driving and bouncing it around it may be coming looser and lost continuity. I would suggest this bypass and see if it solves your problem. It is very cheap for parts and I have already done the research on what connections to use for you. You have nothing to lose by giving it a shot besides half an hour and $10. Let me know if your problem goes away.
Just dis it and it did it to me at part store again i had my tools and did it there and it work Thanks I hope it did solve the issue thanks a million i was having that issue for a while
@@gomezjuan76 you most likely have contaminated fuel or need a new fuel pump. It could be something else but it is impossible to know without the vehicle here. Sorry man.
Thank you for your video....took my daughter's 2011 Jeep GC in to Jeep dealer.....they said her engine has low compression on 3 cylinders causing the problem!!! $7000+ engine replacement bill!! Can you believe that!!! Her engine runs fine once it starts....don't be taken...listen to this fella!! Thank you!!!
Well you are talking about and fixing an issue with the TIPM (Total Integrated Power Module) ......the PCM - is a different thing - (Power Control Module) ....it is the silver flat box in front of the "fuse Box" - TIPM .....the one with 3 big plugs with gazilion wires in each of them . but apart from calling it the wrong name glad it worked for you .....
Yep, thanks. I work on a ton of different makes and models and manufacturers tend to each have their own name for them. You are correct and it is extremely easy to get all that terminology mixed up. I have been turning a wrench for 20 years now and still screw it up because I no longer just work on one type of car.
I was going to say the same. Good video.
Although that’s not the problem I have, I think you bypass idea is great and I appreciate the detail you went to to verify. Awesome work buddy!
WOW! You just saved my 2008 Jeep Patriot from the graveyard. I was minutes away from handing over my title to the Jeep dealer, who said the PCM is bad and they cant fix it. They contacted a junk yard who was going to give me $250 for it. I was reeling because otherwise it is a nice car with only 90,000 miles. I thought I would give this a shot first and woohoo, started right up! My fuse box is different than this one shown on the video, however. We'll see if this lasts and if other issues show up, but right now everything looks good, but now my engine light is on. Oh well. I have a running car. A million thanks!
Omg thank you so much…. I got a multipack of the fuse taps from Amazon for $7 and was able to get my Jeep to start… you definitely saved my butt
Glad to get you back on the road!

Fantastic FYI everyone it worked for me on a 2007 Jeep Wrangler. Hell this advice is worth some beer money or dinner or something to you sir.
Thanks for the comment. It seems Jeep figured this solution out soon after my video was posted. Coincidence?
@@dinstaar you should send them a bill for that factory service bulletin
@@unclemonster48 You know they will never admit it wasn't them that figured it out. If you look at the date on my video and compare it to their bulletin, you'll see they magically had a fix 5 days after my video. Coincidence?
@@dinstaar link or video title?
@@Koshlawg your question is neither a complete sentence nor even thought. You need a link or video title for something? What exactly?
PCM - POWERTRAIN CONTROL MODULE
TIPM - Totally Integrated Power Module (Fuse Box)
ECM - ENGINE CONTROL MODULE
TCM - TRANSMISSION CONTROL MODULE
The relay is on the inside of that control module on the bottom side. It’s soldered in you can’t see it. You have to take the control module out and take the entire thing apart in four different pieces to get to the relay solder it out soldering a new one. There was a video I found on UA-cam on how to take it apart.
No it is not. You may be talking about a different part, on this one I promise you there is no relay. If it were a relay that failed it would not energize even when power was forced to it as I am doing here. If it were a relay this solution would not work. Think about it.
This is a solution that works for only this specific problem in Chrysler vehicles. It is a known problem with a service bulletin published about it.
The fuel pump relay is directly soldered to the engine fuse box circuit board aka TIPM.
I had to completely disassemble the fuse box. It's in thin layers pancaked all together to make one complete fuse box.
2011 TIPM does have it soldered. Pos Jeep/Dodge Chrysler fix is cutting the bottom fuse box wires & tapping into the harness wires & installing at 50amp (large) external relay with a connected 20am mini fuse.
There's also a 20am mini fuse at the mutifuse aka block fuse (+ charging/junk post) thick positive wire. It's hidden wrapped in electrical tape. Hard to see but can be felt by hand & it stick out as "wtf is that"
The TIPM will shut down no matter where you're driving. DGAF. Shuts off at red lights, yields, parked, waiting for the train to pass, in a drive thru, at idling & the worst scariest is when at highway speeds will turn off. The digital guages & electronics still work (HVAC, stereo, sun/moon roof, windows, head lights all work. The analog needles (RPM, speed, coolant) drop dead.
Fck you Dodge,Jeep Chrysler Mopar. A known factory problem that they don't fix other than tell owners they can buy a new TIPM for $1,500.00 programming is extra.
Jeep/Chrysler, Dodge Mopar is a pos.
This is actually a recall just got my jeep done. They cut wires on bottom of TIPM and put an external relay. But now my jeep is doing exactly wat his jeep is doing. Only difference is his jeep don’t have the external relay
My 2011 Jeep Overland started having this issue today, that is what brought me here. Looking at Mopar's website it appears they issued a recall notice in 2019 for this known issue.
@spsjason2 well a technical service bulletin was released after this video. Coincidence? I don't think so because their solution is very similar, just done below the fuse box instead of on top.
This quick fix can be done in the parking lot to get you home, theirs cannot.
@@dinstaar Yes, I agree your fix is great a fast solution. All I am saying is I looked the vin on mopar site and it showed a recall for the relay on November 14th 2019. NHTSA Recall Number 19V-813 FCA Recall Number V62.
@@spsjason2 Yes, no one is arguing with you on that. The original recall solution was to replace the computer. These vehicles did not originally come with a fuel pump relay and relied on computer control (a serious flaw if you ask me). The problem with replacing the computer itself is that it will also fail in time. The solution to externally wire in a relay was not published until December of 2020.
So this is a permanent fix until a fuse blows? That’s incredible. Thank you!
Yes this fix will last you.
The fuse in the first place was blown. Replace it with a new fuse. Instead of doing rhis unnecessary bullshit
No it wasnt. The fuel pump circuit wasnt getting power. So he's feeding the fuel pump circuit with power from the cigarette outlet circuit. You dont know what you're talking about.@@Rockfordfosgate3406

Thank you for that wonderful advice. Mine is a commander 2007 3.0 CRD, crank but no start, DTC P0607 that is turning off most sensors needed to start the car. I just took turbo off and put it back after overhaul kit. Any ideas? I wonder if some ground is not coonected or there is a short circuit. Fuses all look fine from inspection
I’m gonna read every comment this is amazing. I have a 2011 Liberty. I need a voltage tester ASAP
This is a known issue on your liberty as well. Be sure to follow the voltage tests to ensure this solution is for you.

@@jeffb8562 No, sorry. Your PCM is different and most likely needs replaced. Good luck.
Thank you. I actually saw where I had the recall work done on the fuel pump. Problem on the skim issue is thst everyone says I need to send the ECM to someone to delete the SKIM but I cannot take it out and cannot find anyone to do it for me. I’m sure the dealer won’t do it.

I never searched for this video. but UA-cam better know what I should watch! Bzw, great stuff, I made to the end. Cheers!
Thank you for the helpful video and for addressing every inquiry! I’ve just subscribed to your channel.
I have a 2010 Jeep Compass with a functioning battery, but the engine isn't cranking. I checked the fuses and found no voltage in the Engine ASD relay feed 2 & 3 (no. 23 & 26, both 15 amp).
My fuse no. 13 is a lighter fuse (20 amp yellow). Can I use a fuse tap to connect a 20 amp fuse on one side and a 15 amp fuse on the other side? Also, which fuse port should I use, no. 23 (ignition) or 26 (fuel injector) ?
Please & Thank you!
@@MOHITSHARMA-kj3cw isn't cranking or isn't starting? If it is turning over and won't fire, use this solution. If it is not turning over at all, check your starter.
It wasn’t the starter but the ASD relay causing the issue. Jeeps have a known design flaw with this relay, leading to corrosion and starting problems. I cleaned the relay and reconnected the wires, and it started right up.
Thanks for your response though! I’ll definitely keep following your videos for more helpful tips.
@@MOHITSHARMA-kj3cw that is great. I was trying to fish for some more information with the question isn't starting or isn't turning over at all. Yeah, a bad relay is a common problem that will not allow power to go to the starter. Glad you got it.
I appreciate you very much sir letting us all know about this information . A year ago my 2005 JGC security went off when I put key in door and it shut the fuel pump off I searched it here on UA-cam and found this video it worked 💯 so I am Thankful sir!
I’ve run Jeep this way since but it done it again so my question is Now What? I got fuse tap’s just like you have but now it’s done it again what can I do to bypass it.
I need to know what is happening when you check the electrical. Are you still forcing power to your fuel pump from an auxiliary power on 12 volts?
@@dinstaar yes I am
I was 75 miles from home when it shut fuel pump off. So I ran a hot wire from fuse box under dash to positive wire on pump and I put it on a switch on dash so I can cut power when I cut engine off.
So now I’m home the door locks and power windows and of course the fuel pump doesn’t work. So I’m guessing it’s the TIPM or PCM it’s something that’s stopping power from these components. But I got it home and I have 1,500$ in it been driving it for a year and a half so if I can personally fix it I will but I want be paying anyone to fix it.
@@williewaynewheelbarrowtoma4436 did you protect this new hot wire with a fuse? How many amps was it running? The reason I ask is because you may have pushed too many amps to your PCM causing damage.
We already know your PCM is damaged because of the original failure. You can order one and put it in yourself. It is not too difficult. However, by grabbing a random wire under the dash you may have caused more damage. I would start with a PCM and see where you stand after that.
@@dinstaar I couldn’t tell you I just ran a hot wire from a fuse to pump positive wire and I heard it start working and I come home
@@dinstaar I want to Update you about my 05 Jeep Grand Cherokee 3.7
Idk how long it will last again this time but like I said previously got it home had to run 45 Top speed because not only did it shut fuel pump off but this time Transmission wouldn’t shift into high gear along with the windows wouldn’t work also the stereo didn’t work that’s the first time it’s done all that the past 2 times security has just shut off the fuel pump. Here’s what I did to make it work again after I got home. Took the the Tipm completely out of car along with the Flat Thing mounted to the side of Tipm I’m guessing it’s the Computer are it maybe part of the Tipm either way I left it mounted to the side of Tipm but I Took these things in the house . It was terribly Cold. So next day I took my Big magnifying Glass and pocket knife got some Brake cleaner got it under a good Light so I could see well and I found that a few pins were a greenish color so I scraped those and one of the Plugs that plugs in bottom of Tipm has either been partially eaten away by battery acid or something got hot the pins were all there and complete some of the Plastic housing was gone and exposing A few pins. Wasn’t in need of going anywhere for a couple of days so I kept Tipm in house When I put it back on Jeep and connected plugs I coated the side of Tipm plug where it was damaged and let it dry good and next day when I connected battery I heard fuel pump start pumping. It started right up and windows were working stereo came on and transmission shifted correctly so it’s few weeks now and so far so good.
It"s not a PCM. The TIPM is located in/under, is part of the fuse cluster. The metal computer looking thing in front of the fuse box is the PCM.
After replacing the fuel pump/3.7 WK- Im now having a problem with a vapor lock and my new pump is making a ringing/humming noise off and on-is there a way to fix it with a inline check valve or inline filter of some sort. I have to release pressure on the fuel rail to re-crank it after it runs for more than 20 minutes/ which is a possible fire risk.
hello mr..i did it before...but its better to join a relay 30amp by connecting a real circuit with the dark blue orange wire below the box under the m25 fuse anyway i like the piece you used its a simple way at least to move the car
No one is going to pull the entire box out when they are stuck somewhere, or even just in their driveway. Your way may look more tidy but sounds like a lot of unnecessary work to get down the road. Thanks for your version and opinion though. Where is your video?
In my city Nazareth we have company for the Jeep Grand Cherokee I hope you going to fix the electric problem thank you my friend
There is one issue... The PCM still needs to control the fuel pump relay. The fuel pump is ONLY supposed to run during crank and while the engine is running. NOT while they key is set to accessory or run. If you are involved in a collision where the engine stops but the fuel pump continues to run, if a fuel leak is created by the collision, then you will squirt fuel continuously and risk substantial fire.
Thanks Chrysler works again 🎉
Great!!!
Hi. Great comprehensive vid. Thank you for taking your time.
My key light (key with a line across it) is showing and so it is most probably due to either the key, skim or the PCM unit. Will bypassing the fuse like you did help solve my problem? Your kind advice will be much appreciated.
Not likely. This bypass only turns on the fuel pump. Good luck.
@@dinstaar Thank you for your reply. Much appreciated.
Stay safe and healthy!
I have exactly same problem on my TJ jeep
@@bearclaire6894 My issue took forever to figure out. Until the mechanic found that its the AC unit that was faulty and so somehow affected the electronics causing the key light to turn on (and engine to shut down randomly). I changed pretty much everything else but only until I replaced my AC unit was the problem solved. The mechanic said he was sure it was the door lock switch panel that may have caused the issue but turns out replacing that didn't help.
Yours might be caused by a different issue. But I hope this info helps as nobody seems to think a faulty AC unit (the unit in your dashboard) could've affected something so unrelated.
Good luck!
Do you remember what exactly they changed? I have the same issue. My heater core went out and soon had that red flashing key on the dash which prevented the vehicle from starting. Thanks for any info.
Hi. I have 2002 grand Cherokee overland. Yesterday it stalled like it was starved for fuel. After sitting for a bit it will start and run for a few seconds. I think I have it narrowed down to the skim and or pcm. Does this bypass the skim as well as the pcm. The light on the dash that shows a key with a line through it comes on.
Your computer system is different on an 02. No promises it works. I don't know what you are referring to about a "skim".
Sitting for a bit and then working is typically contaminated fuel by the way. The reason it works is you are giving all the contaminants a chance to settle. When you stir them up and mix them into the rest of the gas a problem exisits.
@@dinstaar the skim is the black ring around the ignition that reads the chip in the key. It sends a signal to the pcm only providing power to the fuel pump for 3 seconds and then shuts it off. Security feature. Seems to be a constant issue from99-04. Most videos have the pcm “wiped” and the skim removed as not to reprogram to that specific key. In your opinion, opinion only, would testing your technique cause further damage?
@@kevinkelly3456 ok, now I know what you are saying. I have honestly never dealth with that specific issue. I can promise you though that wiping a computer is easy, getting it back to correct perameters can be a challenge. Be prepared to send it off for reprogramming if necessary.

@@Ayemsladychay Absolutely not. This will in no way help you. Smoke and throttle response is most likely a mechanical issue.
Would this be the same for a 06 commander? Having the same issue. I believe the anti theft system is shutting down the fuel pump. When I reprogram the key it works but then stops working. I did have a pcm code but it went away somehow. Any advice would be appreciated
Did you ever figure out your commander problem
I have a 97 Cherokee and I just got a new pcm and it wouldn’t start and so I ran a bypass in my add relay for months and drove it that way. I didn’t realize that there was possibly a skim immobilized problem . The I’m has the skim removed but I can’t find the immobilized on the vehicle and I’m at a crank no start again and this is my every day … any ideas?
@@katiechowen4328 on a 97? Honestly no. I have never worked on one.
Awesome! Will this work for a 2010 Jeep Liberty too? If it does then I'll save a butt load of money if this ever happens!
Do the electrical checks I do to verify the problem. If your voltage behaves the same, then the problem is the same and this will work.
Just wandering with my 2000 Jeep grand cherokee Could I do this with my key light on to bypass the skim Model ?
Nope
Hi. Thanks for the video. My Jeep seems to be a little different. My fuse box has the following markings: HOLP SW / blower, cooling fan, battery acc, ign run-start, IGN ACC/RUN, starter hbl, ac clutch. That I need to use ign acc/run seems clear from your video. But what is the other one? I can't find number next to the fuses, so that didn't help.
You either have an older or a newer jeep if your box is different. Therefore you have a different PCM and and this is likely not your solution.
Keep troubleshooting.
@@dinstaar thanks for responding. Mine is a 1997 4.0 Cherokee. It sucks that there are so many differences between Cherokees. Some other solitions offered on UA-cam also didn't pan out and were probably for a different model/year. I'm starting to lose faith in finding something that will work.
@@rtv9_noord Troubleshooting is the most difficult part. Why do you think we charge so much? Because it isn't easy. Most of the best techs go to an expensive tech school, then get several OEM and engine certifications, then have to gain years of experience in our field to be considered any good.
Sorry but it is really impossible for me to help you without having your jeep here to see it, hear it, and feel it. Good luck.
@@dinstaar
Thanks for your respons.
I wish there was an expert nearby, but there doesn't seem to be. I asked around.
I thought the problem is simple: the remote doesn't work. So diagnostics are limited to whether the key fob is defective, the receiver, or the system that manages the signal and cuts the fuel supply. I had hoped that circumventing the security system would be something I can do myself since shops here abouts have to do the same thing I'm doing: surf the internet, ask around and just try stuff that is presented here on UA-cam. Two down, three to go.
@@rtv9_noord so everything works but the remote start? Is this an aftermarket system? To be clear what I am doing in this video does not bypass security in any way. It bypasses a known problem in the PCM that fails to provide power to the fuel pump.
Let me know if everything works besides the remote start.

Thanks
If your vehicle starts and runs most the time, you most likely have a different problem.
WOW ,
before you all start blaming this guy for it not working why not check if you have fuel pressure at the fuel rail ?

do you have spark?
fuel pressure ?

Thanks for watching and paying attention. I am pretty clear that this is the solution for a specific problem but some viewera don't catch that.
You are 100% correct that in order to know if this will fix your Chrysler PCM problem troubleshooting must be done first. This is not a magic solution to fix every problem on a vehicle.
@DINSTAAR I ordered a PCM but I intend to try your solution first on my 2011 Jeep Liberty. Its starts and keeps running only when the gas is held down (but runs rough), stalls out when released. The starter also runs on after the vehicle is started. My mechanic said I needed a PCM after replacing a few coils and the issue did not go away. They tell me that the cylinders were not communicating with each other and some cylinders don't display proper compression. They also said it was not a mechanical problem. They never mentioned the fuel pump not working properly. Please let me know if this sounds like your solution would work. I understand you can't give me a definitive answer but a percent chance would be nice.
This solution will absolutely not fix your issue. Your PCM is malfunctioning on several levels and needs replaced. This only addresses the common PCM failure of powering the fuel pump. If your Jeep starts, this is not for you.
@@dinstaar Thanks!
Hi my 08 liberty has same problem as you describe, what did you do to fix it thanks
@@kurtengel6029on mine, It wasn't anything to do with the computer. It was in the cylinder but they wanted 4k to fix it so I bought a renegade and got 400 for the dead car on trade in
Hey buddy quick question if I change the computer in the car for other reasons.. Will this get rid of the security part of my computer so I can just turn the thing on I'm going to try a junkyard computer hoping your hac will bypass security
His hack is specific to fuel pump failure due to a known issue with the PCM. It has nothing to do with security.
I am not sure how Jeep disables for a key programming issue but I believe the starter will not turn over. If I am correct this bypass will not work and neither will a new PCM. Sorry man.
At a boy you’re the best it worked just fine on my 2012 Jeep Grand Cherokee
Bro I'm having the same problem right now ,JGC 2012 will crack but will start can you tell me what to get from the store and explain how to fix the problem
Was this done after the recall in which an external fuel pump relay was installed to bypass the tipm?
I'm getting p0628 code, crank but no start in my 2012 grand Cherokee 3.0 crd
This bypass was done before the recall. I figured this out myself, Chrysler could not. Their recall solution is a modified version of this they took credit for, they just added a relay where I rely on a fuse. Check the date of my video, 5 days BEFORE they published their bypass.
@@dinstaar Thanks for the response, I thought I narrowed down my issue to the recall wiring being faulty, after cutting out the joins the dealership put in and putting in fresh crimps the problem is not resolved. The next area I plan to look at is the pink control wire, since during the recall process they pop the pin out of the harness plug, it might not be seated in properly and isn't making a solid connection to the tipm.
If this fails to fix my issue I think I will try reversing the recall, remove the relay and try your pcm bypass solution.
I'm not convinced it's a fuel pump issue just yet.
@@bloggs24 If you do the electrical checks for voltage I show in this video, you will know if it is a fuel pump issue or not. Do not skip that step, it is the most important part.
Hey I don't see a lift pump fuse on my 06 Grand Cherokee where would it be located??? I really don't want to pay all this money to get it fixed in a shop
If yours is an 06, you have a different problem and a different PCM. This won't work.
Tell me your symptoms and I will attempt to point you in the right direction.
Has anyone ever done this fuse tap trick on a Jeep Commander?? They only made them from 06’-10’. And I have a 06’ and the fuse box is way different and I can’t figure it out I bought all the fuse taps and stuff for $30 and will be towing it to the dealership for a $900 TIPM replacement today if I can’t figure out how to fix it.
If you are in over your head do not attempt this repair. I can tell from your comments you need to go pay someone.
Will this work for a 2004 jeep grand cherokee Laredo. The person I'm buying lost keys if I change the key cylinder and do this bypass will it start?
Your fuse box is very different than those made from 2011 to 2022. This is a specific solution for a very specific problem and that is all it is. Depending on your model or anti-theft equipment your solution is going to be very different.
Im working on an 02 Grand Cherokee 4.0.
I believe the Skim system has failed.No fuel.I installed a new mopar fuel pump and filter.Still no fuel.
The key light on the dash stays on and I also cant get my scanner to link up with the ECU.Wierd.
Im wondering if this trick would work to be able to bypass the Skim system.
This is a very specific bypass for a very specific failure. It is not a fix all for any problem. You seem to have a damaged PCM or a skim issue. That is very different.
Good luck.
@@dinstaar I'll keep digging into it.Thanks for the reply!
14 wrangler intermittent crank no start. Usually, we'll turn the key back off and will start the 2nd time. Was this also your your problem?
It really could be a few things. I don't have your jeep in front of so I can only try and tell you to check a couple things.
First, does it only happen if you have parked it for awhile? If so it is likely you are losing prime. Cycle the key on, wait about 30 seconds, then start. This will prime your line.
Second, do the electrical checks I show you in this video. Your PCM issue may have started. Key on and see if you have power where I tell you to look in the video. If you do not, do this bypass. If you do, you have a priming issue.
@dinstaar if it's losing prime, would it more likely be a fuel pump issue or a vapor lock issue. I'm leaning fuel pump, but would like your opinion. No visible fuel leaks, currently.
@@brianchambers6225 Troubleshooting this issue over UA-cam comments is impossible. Sorry. I would need the vehicle in front of me and a lot more information. If you are near Waco, TX swing it on by and I'll take a look.😀
Most commonly this could be your fuel pump, fuel filter, a cracked or loose line somewhere, or contaminated fuel.

@@brianchambers6225 It is most likely one of the things I mentioned. Check those out and you'll find the problem. Good luck.

Tim, without your Commander here in front of me I cannot troubleshoot it. If you Jeep will not start because your PCM is not sending power to your fuel pump, this is the fix.
I am saying if I bought the fuse tap will this fix my jeep commander
@@timland7553 Bring your Commander over and I'll look at it. I cannot troubleshoot your specific vehicle's issue over youtube bud.
It does sound like a good TEMPORARY fix!!! I dont understand yet how it affects the pcm....or if it does.
It does not affect the PCM at all. The PCM is bypassed and is no longer in control of your fuel pump. Your PCM is broken, that is the problem. This fix is PERMANENT.
The PCM has a known issue of failing in this manner only. Besides not providing power to your fuel pump, everything else works fine. You can replace the PCM if you like, but it will fail again this same way. It is a known PCM flaw. Many people have replaced their PCM to have the same problem down the road.
@@dinstaar Thanks so much for replying!!! I understand fully now!!!
Will this work on a 1996 Jeep Grand Cherokee if the PCM is bad
You will have to consult your schematic. I do not believe this was a known flaw in 1996.
Hey I have a 2012 grand Cherokee, installed a new battery, starter, fuel pump relay kit, fuel pump is working (checked with a jump wire on 87-30) same test on the starter relay.... this fuse wire didn't work. Checked all relays and fues'
Starter still spins but doesn't crank, will crank for a second randomly
Is it time for a new pcm?
I need a better description of "starter still spins but doesn't crank, will crank for a second randomly."
Are you saying the starter is turning on command but the engine will not turn over? Or are you saying it is not cranking long enough? Please clarify.
Also, you cannot check to see if your fuel pump is working with a jumper wire. So please tell me what you did here. You can check your fuel pump by checking power at the pump, or cracking a line and seeing if fuel is coming out to the engine.
So it spins but doesn't engage with the engine. Randomly it will catch and try to start, have got it to actually start twice. I have put a jump wire on the 87-30 in the fuel pump relay and I do hear the pump working
@@5K7WLKR your starter is not engaging with your flywheel. You will have to pull it out and bench check it. Make sure your pinion is pushing out your gear so it can engage. Your problem is that the gear on the starter is not turning your flywheel.
Could be your Bendix, solenoid, or a bad electrical connection. Best way to check it is to pull it out and put 12 volts straight to it and see what happens. Be safe. You better hope it is your starter because if it is the gears on the flywheel it is not a small job.
Crap, its brand new 8hrs to install myself lol (new motor mount aswell)
Sometimes new parts are bad. Sorry.
If it's not the starter, then get upset because the alternative is worse.
My friends 2009 Jeep Grand Cherokee with a 3.7 will not start. It will randomly start sometimes when we try but it’s not having any engine codes. It will start sometimes and we replaced the fuel relay fuse and it ran for a week then wouldn’t start again, it started back up and it’s a constant pain to try and find the problem . Suggestions?
I suggest you take it to a mechanic who is very good at electrical issues. There could be a ton of different things causing this issue. If you are in the Waco area let me know.
I have a 2012 jeep liberty after running for a day fuse 28 blows . If the engine is hot it will keep blowing the fuse once it cools down I relace the fuse and will run but same happens after a while. Will this work in my situation ?
Of course not!!! The fact that you would even consider any relation between this video and your problem tells me you should not be working on your Jeep yourself.
Find a local shop and take it there.
HI Dinstaar does this work on a 2012 Diesel Jeep Grand Cherokee thanks Matt

@@jadenfox3445 you did not mention air flow or any check engine lights. Check for air restrictions, look for a fault code that could be related to the computer cutting fuel. You could also crack a fuel line and see if gas is getting to your engine. Good luck.
Great idea in a emergency but fuel pump is live with the key in the run position. What if the person gets in a front end crash and springs a fuel leak.
Pump is still pumping gas and the operator is unable turn the key off . Need I say more!
This how is was always done before. Plus, this would still happen anyway. Your fuel pump is turned on by the PCM the minute you turn the key. They simply use the PCM instead of a relay now. It is not any more dangerous by running your vehicle this way.
Great question. Thanks.
i noticed you had the 1st pcm plug out do you have to have that pulled out
There is no wiring harness to plug into the PCM on a 2013 Grand Cherokee. There is no need to unplug any wiring harness if your model has one.

@@timland7553 I need an electrical schematic. A picture of your fuse box would tell me nothing.
Put one long lead of a multimeter to your fuel pump (where you should be getting power on key on). Do a continuity check at your fuse box to see which fuse beeps. That will be your fuse my friend.
I have a problem with my Jeep g ch 2011 and suddenly on the road a burning smell came out of it. I replaced the battery, fuse box, ECM PCM control model, and also replaced the alternator, and there is still something that is damaging all of these things and the car stops again and a burning smell comes out of the alternator and a clicking sound from the tipm.

If your alternator is not working, the only solution is to replace it. You cannot regulate voltage that is not there.

@@marcodeluca4068 It is impossible to diagnose this over yahoo comments. However, I can tell you that your PCM has absolutely nothing to do with it. Your alternator is directly connected to your battery. Look at your wires and battery terminals. Look for broken wires, corrosion, a loose connection, or a bad ground. Also, test the alternator directly at its connections for voltage between 13 and 14 volts. Test the battery too, it may be bad. Follow these directions and you will find the cause of your problem.
@@dinstaar Battery and alternator are both new and checked but if I connect the alternator to external voltage regulator it should work right?
@@marcodeluca4068 Modern alternators have regulators on them. You should not have to connect it to an external one. What is your voltage at the alternator? Jump the van and connect your multimeter to the posts on it and see. You should get 13 to 14.5 volts. If you don't, your brand new alternator is bad. If you have good voltage, check your connections and make sure they are tight ND not corroded. Follow the wires from the alternator and look for breaks.
Hi Mr. DinStaar. I have a 2016 JGC Laredo. While driving i lost all power while at a red light. Had to get jeep towed.

And sometimes it just on its on continues to start but want turn completely over. Can you share some wisdom with a young buck ( 19yr old ) to help me get my baby back running
Any mechanic who is honest with you will tell you a diagnosis should be done in person. Anything else is a guess as it could be literally hundreds of things causing your issues. Your issue could be as simple as a bad ground, loose battery cable, PCM, fuse panel, etc...

A good mechanic will he honest and tell you, to do it right I need to see it, touch it, and hear it in person.
It is most likely one of 3 things.
1. The battery. Make sure you have 12 volts and load test it.
2. The starter. Jump the electrical contacts and see of it turns over after you check the battery.
3. The starter relay.
It could be something else but those are the top 3 culprits. Good luck.
Hello! I have been having a similar issue but not exactly the same. On my 2012 JGC, it will crank and start but imediately stall. Second start it will crank until it times out. Third start it starts fine and stays running. Any ideas?
Any honest mechanic with experience will tell you that without the vehicle in front me I would be guessing. It could be a large number of things. Any chance you are in the Waco area?

Open your fuse box and look. If yours is the same as the one on this video, it will have that fuse there. If the fuse is missing (because it does not have a lighter), you may have to stick a fuse in it.
do you know if the gauges still read out despite the PCM being byapssed?
I am only bypassing to operate the fuel pump. No gauges are effected at all.
@@dinstaar thanks!
@@Electronica27 no problem
If so, which fuse should I connect to the other one please
I cover that extremely clearly. I literally show you as I am working, while telling you how to do it. Then again I say it at the end of the video with the numbers of the fuses and the description of what they are for. If you can't follow that, I don't know what to tell you.
Hello Sir, will this work for Jeep Cherokee 1997 please?
Nope. Different computer. This is for a specific known failure of the PCM.
Will this work on. 2001 Jeep when with the 4.0?
Of course not. You have a completely different computer that does not fail in this manner. You have a different problem.
Does it work on the 3,0 crd
Year of Jeep? This doesn't apply to my Jeep. You didn't mention if you diagnosed for a bad fuel pump or did u skip that info.
If you watch the begining again, you'll see I diagnose that there is no power getting to the fuel pump at all. The PCM is not sending power to that circuit. That is why there is no power to that fuse.
This is a common issue for all vehicles Chrysler uses this computer in. The particular Jeep in the video is a WK2 (2011 through 2013). Look for this specific failure in many Chrysler products using this PCM.
Thanks for you video your the man.
2012 Jeep Grand Cherokee. I had high hopes for this solution but sadly it didn't fix my problem. I guess I'm faced with having the car towed to a dealership, where there's a two week wait for the new PCM and installation, if that is indeed the problem. A local mechanic thinks it could also be the fuel pump itself. Either way, I'm out around $1000 for this.
You will know for sure if it is the problem by doing checking voltage exactly like I did to see if the fuel pump is getting power when the key is switched on.
If the results you get are like on my video, it is the PCM. If you jump with fuse taps like I show you, then power is getting sent to your fuel pump. Have you cracked a fuel line to see if fuel is getting pumped to your engine? Have you checked for power at the fuel pump itself? There my be a broken wire.
@@dinstaar I checked the power with my voltmeter at M25 (labeled "FUEL/DSL LIFT PUMP" like you said) and zero volts. Jumpered to M7 which showed 12.5V on the meter. Once jumpered, I saw 12.5V at M25 but no start. Could it be I have a combination bad PCM and fuel pump? For what it's worth, we run this car almost exclusively on E85 ethanol, popular in our area. (Yes, it's a Flex Fuel engine!)
@@zumajim Well E85 is garbage. It is alcohol, not gas so it has no lubricant in it and is very rough on everything it touches because of that fact. When you factor in worse gas mileage you'll find that in the end it costs you much more than gasoline because of the added maintenance and repair that you have to do when running it.
Your likely causes now are a loss of prime, a broken wire going to your fuel pump, a cracked line, a bad fuel pump, or a clogged fuel filter.
Start by cycling the key on and off several times letting the fuel pump run for awhile each time. If your lines are dry, you need to give them a chance to fill up and build pressure. If that doesn't work, open a fuel line near the engine to see if you get fuel coming up there. If you don't time to check the fuel tank where the filter and pump are.
Good luck.
@@dinstaar Hey just wanted to report that my car started after all with your jumper fix! A different post mentioned "cycling between ACC and RUN a few times befor engaging starter" and that helped, I think. Either way, she now starts reliably and we cancelled our appointment with the dreaded dealership (which is still almost two weeks away... That was the best they can do!) So add me to the long list of very happy followers. Can't thank you enough, sir!
I’ve got a 2012 Jeep jk. Code u0100 no communication to pcm ecm (A). No start, would this bypass start my Jeep haven’t tried it but when shops open will definitely give it a go.
This is specifically for the problem of the jeep turning over but not starting. It is for when the PCM has failed to send power to the fuel pump.
You may have a different issue but good troubleshooting is not possible when I am not in front of the vehicle. Are you in the Waco, TX area?
2004 grand Cherokee has a problem with hard starting. Change the fuel filter first couple times it started right up now it takes three attempts burned out the starter new starter. Started right up couple times now we’re back to three attempts before it starts. What could be the problem
That sounds like you are losing prime when you park it. Let me guess, it happens when it sits for a bit?
Will this work on a 1998 grand jeep cherokee
No. This is for the WK2 years. Your TIPM and PCM are very different.
i have a 2015 JGC and it's having issues keeping the battery charged. It will click once when I push to start, or when charged it might turn over once or twice. When hooked up to the bigger battery charger it was warm and turned on immediately. Now sitting on the small battery charger for a whole day it will only turn over once or twice, then click, nothing. Any ideas?
You have the symptoms of a bad battery my friend. As a battery ages it will charge but either not hold it, or lose cranking amps. Sometimes they even show 12 volts but fall flat as soon as you put a load on it. You need voltage and amps to turn that engine over.
Clicking noises is almost always a starter solenoid attempting to engage but cannot because of low power.
You can remove your battery and take it into any auto parts store to have it tested. However, be prepared to buy one when you're there.
Will this work for the pt cruiser if the wcm goes bad?
This is not a solution for the wireless control module.
Are these the main ones too buy or are there others???????
What are you asking about?
Would it be the same ref: jeep compass 2011?
Look at your fuse box and you tell me. There is a map printed right on it. I don't have a Compass in my driveway to check.
If the fuses I point out are the same as yours, do the voltage checks I do. If your results are the same it will work.
Was the car turning on after a few tries or just not turning at al i have a 2013 wrangler when cold it turns on ok
After running and parking and turning off for about 20 min it will have it just crank and later turn on
Mine started off that way and then would only turn over and start again. My theory for you is that the PCM electrical contact may be intermittent. Meaning the contact is separating and is weak but may not have lost all contact yet. When cold the electrical connection has not been vibrated apart, after driving and bouncing it around it may be coming looser and lost continuity.
I would suggest this bypass and see if it solves your problem. It is very cheap for parts and I have already done the research on what connections to use for you. You have nothing to lose by giving it a shot besides half an hour and $10. Let me know if your problem goes away.
Just dis it and it did it to me at part store again i had my tools and did it there and it work
Thanks
I hope it did solve the issue thanks a million i was having that issue for a while
@@gomezjuan76 Good luck Juan! Touch base if you need me.
@@dinstaar sorry to tell u but it did it again
Will leave it in for more time see what it does
Thanks
@@gomezjuan76 you most likely have contaminated fuel or need a new fuel pump. It could be something else but it is impossible to know without the vehicle here. Sorry man.
