- *Update* the cause was the driver wire for fuel injector 6.... ran a new wire, working perfectly now, weird that it didn't show up in the continuity test or voltage test
a video on how to change a fuel injector on a 2002 Dodge Caravan 3.3L. I'm not a licensed mechanic so this is for entertainment purposes.
Here is the link to the Caravan service manual:

I know this video is 11 years old so you probably won’t see this. But I’m 30 years old and you explained how to do that job just like my dad would have. I couldn’t have done it without you. Thanks man.
I'm glad it helped you out. Cheers!
Ten years later and still spot on. Thanks for a great video!
Fantastic! A big thank you to your daughter for the good camera work and a huge thank you to you. I have the identical van. Been chasing a hesitation gremlin for a week now. @ about 1800 rpm while driving it starts to shake and hesitate. Once I push past that, it's ok as long as the RPMs are high. I've changed the plugs/wires. No dice.
Replace motor mounts?
fact that the BAT light on the dash comes on and then goes off as well as the one code stating the 5 volt supply is low, certainly wants me to check out all the wiring first before replacing such an expensive item. Thanks so much Steve, you have certainly ended my anxiety and now I can proceed to troubleshoot in a much more logical manner.
I didn't have a fuel injection problem with my van at all, but thank you for the video, I watched for the sole reason that like you said, lack of video's on Dodge Caravan's, very informative, you pinpointed too many helpfull areas to list, bolt, computer, injector, hose, reservoir locations, harness connections... and camera operator was on top of it.. Thanks.
Decent DIY mechanic here, and you did a great job explaining everything! I have a 2005 Chrysler T&C 3.8L, and like you LOVE my vans. Very useful for carrying cargo and people. ~200K mi.
Thanks! Cheers!!
Really only came here to see where the petrol/gasoline injectors actually are, since I've got 12 injectors on my Chrysler Voyager instead of the usual 6 (I've got 6 for petrol and 6 for LPG), but I never would have guessed they are under there. In the end I watched your entire video, because it helped me a lot to understand what's where. Thanks for that. 👍
Nice vid, not many out there. Did this on my own without the vids...there isn't really a need to disconnect the fuel rail from the fuel line. I was able to swap out the injector seals and reseat, and continue on. Great vid!
Thanks for having this up. I just used it to help me replace my injectors and it saved me 400. Though I had a much harder time unplugging all the wires.
Hi, I just wanted to take a second to thank you and all who do these videos. Your videos are very thorough and great for a novice like me. I'm sure many others either forget or are in a rush or just don't know how, but all appreciate. Wish you had shown the back wire and plug removal so I could have had a better idea of how much will be involved. These videos are important and a tremendous help, especially in this bad economy where a great majority of one time middle income Americans, now working poor are doing work they never would have thought of doing 20 years ago to save a few bucks.....Keep em coming!!!
your videos on the Dodge caravan are AWESOME!!! Thanks for filling this gap.
Thank you for showing how to disconnect that electrical clip! I'm just starting to work on my "new" van (1996 GC) and those electrical clips have been driving me crazy trying to figure out how to get them apart. The trick for disconnecting the throttle cables was GOLD! Also how to "relieve pressure in fuel line" but hey, don't get that on your skin, might as well drink it. no bueno... anyways, really appreciate the DETAILED descriptions. If I knew how to do this I would n't be watching u-tube.
This is one of the best how-to videos I have seen yet. Easy to understand, easy to follow, and makes a seemingly difficult repair job very simple. Thank you so much. I learned a lot from this video. Sometimes it is not about the video as much as being able to take what I learn from this video and apply it to a few other videos to make my trouble shooting my 2002 Grand Caravan Sport a lot more informed and knowing what to look for. This is association, and for which I will now tackle the job
Incredible you saved me 700$ BUCKS changing intake manifold + fuel injectors + fuel rail. Awesome Thanks a million. This time my Garage will not rip me off when i can do the job.
THANK YOU ! Just finished replacing an injector. Followed your steps and it made it SUPER easy!
Needed to remove windshield wiper motor tray first to make it easier. My wiring harness was good also.
Replaced throttle body gasket and plenum gaskets. PCV valve was a bugger but replaced it along with valve cover gaskets.
Thanks again!
You're welcome! Cheers!
I know this is an old post but it saved me $80 on my 2000 Dodge Neon .. i found your video last night and changed my injector this morning .. took about 15mins ... thanks for sharing
I have a 98 grand caravan awd with 418k on it.... still runs like a champ.... it has a 3.8 liter in it....:)
Hi, thank you for the video, I have a DGC 2003 and my mechanic did everything you have done with no difference, just a lot of money that he charged me. If I'd watched this video, I'd done it myself.
Nice common sense video. Thanks for taking the time to do it. OUTSTANDING work!
Thanks Steve. I've watched a few of your videos over the years of getting the 02 Caravan sport up to 235K. Having knowledge of my journey ahead of time is invaluable, not to mention saving me tons of frustration when I run into things like the bolt on the back of the ps fluid res. Thanks again much, cheers and stay free.
You're welcome! I wish I still had my caravan, but everything rusts away when you live near the coast. Cheers!
@@steve45ca All plastic rots fast in AZ haha. No clips make it.
I have a '98 Chry. T&C AWD with 253,000 miles on it. Bought for $500, from salvage yard before it would have been titled as salvage, needed some repairs. Water pump, ignition module, tranny shift module, O2 sensor. I performed all the work, saved quite a alot of money. Had shop do wheel alignment. Latest MPG check old school method, not by the on board trip computer, divide miles traveled by fuel used resulting in 23.779 mpg. I am a happy driver! ;)
Thank you for taking the time to make the video. It was the catalyst for my injector replacement project and gave me the pointers that made the process go smooth and free of issues.
While I ended up only having to replace an ignition coil, and mine is a 2014 Grand Caravan, this video was super helpful and gave me other info I needed, like cylinder position, to do the job I needed to today.
Doing this now got one of these vans for free for the family. Not much on this van works or runs maybe someone just swapped the good for bad parts. This thing floods and won't start without holding the gas pedal down. I'm going to attempt to clean the existing injectors then replace as needed. Thanks for your video not so much the quality but so much your demeanor and explanation was easy to understand. New Update just replaced all injectors. Now to address low fuel pressure.
Transmission went today after replacement of injectors got no forward gears just whines. Reverse works. Ugh.
I added Shudder fix and transmission is working again. Few.
The water pump needed replacing, so I did that and an oil change last night. No dice, but wasn't expecting a fix anyway for that, lol. The codes are reading misfire on 2. I was going to try the fuel filter next and then the pump. I didn't feel ok about "injectors", I'm no mechanic, a lot like you. lol I may just go ahead and do this. Thanks again for the video man, you just helped me immensely!
Thanks for doing this video. I have the same problem with my Dodge Caravan. I may not be able to do it myself but at least I know how to explain it to my mechanic. Good job!!!
You just saved me a load of cash! :)
Thank you very much for taking the time to upload this video.
One side note. The PCV valve is FRAGILE cheap plastic. Very easy to break while trying to remove the hose!
Enjoyed your video, very well done and very instructional. I was having trouble with the engine misfiring in my 2005 Town & Country. Turns out that it was just a loose spark plug. However, I noticed that my #6 injector must have had a bad ground as well, because I noticed that someone replaced the ground by running a new wire! Life imitates art once again!
no body on UA-cam has a video as good as yours thank you so much you have a gift for video editing
Good video! Thanks I am helping out a friend of mine, feeling very confident about doing the job saving this young family $300 in repair bills at the repair shop! Good on you!
Update - where was the bad wire found? Near the injector? How far back?
Fantastic video and great job Steve. It helped make my fuel injector job a breeze today! Many thanks and greetings from Southern California!
Im glad my video was helpful! Cheers!
Very cool tutorial video Steve,almost seems easy enough that I could do it. My biggest problem is remembering how it all goes back together lol It's simple enough to take it apart. I was kind of hoping your where going to start her up at the end so we could hear that puppy pure haha hope this did fix your issue,Take Care!
I just got the spark plugs, the wires, the seals and fuel injectors today. I'm replacing the whole thing just to be on the safe side, the previous owner didn't maintain it properly, the wires for the spark plugs were different colors on the front from the ones on the back. But thank you for the tips
Excellent video! I was disappointed though. I wanted to see and hear the 3.3L actually run after it was all put together.
I just completed mine today after receiving my fuel injectors. For whatever reason, my 06 did not have the fuel pressure release. Perhaps I missed you say something? I'm pretty tired lol. I do want to say, thank you so much for this video. It made it really easy to do. I can't even tell you the amount of things I've done to this van already by myself (definitely helps make it a bit easier I'd say). I'm not really sure what my issue is as it started around 160k miles. But my fuel mileage is horrendous. It was really good when I first got the van around 130k. I figured I'd just replace whatever I can that affects the MPG until it's fixed (hopefully). She deserves the new parts anyways. I love this van so much!!!
Hey Steve that video was off the hook, I have a 2001 caravan and I'm about to change my plugs, wires, ignitors, air cleaner, PS reservior and by removing the wipers and assemby below the winshield, I'll have complete access to everything just a thought the next time you change your plugs.
This all points to a bad PCM. However, I found pink insulation jammed up under the plenum and around the injector wiring and around the injectors. Codes also set for Open #5 and Open #6 injectors. Mice may have chewed into the wires under the plenum. This video has shown me how to do the continuity checks from the PCM Wiring Connectors to the injectors by removing the plenum and how to do the resistance checks as well in this area. Also your update of bad signal wire proves I need to....
thanks for this video
many first time jobs can be a little daunting due to little hidden bolts and hoses, trick of the trade shown in this video makes things a lot easier
You are complete mechanic. Great job
GREAT VIDEO MAN, IT HAS PLENTY INFO AND DETAIL INFO HAS YOU SPOKE IT WAS REALLY GOOD MR STEVE. KEEP UP THE GOOD WORK MAN.
Thank you for this awesome video!! We will be trying this tomorrow.
0:10 My 2002 Grand Dodge Caravan 3.3L V6 was getting code P0206, I watch this video which was real good and led to
do it, what I did first is that I only changed number 6 injector. That did not work still P0206, so I decided to change all six injectors but no change I also changed the injector wire harness before I did the testing. I tested the injectors ohms and all of them were 1.28/12.8 and the voltage was 12.4 Volts that meant they were ok but still had no pulse on that injector 6, (Use a long screwdriver to listen for pulse). After reading for a while came up with the PCM problem, that probably was the injectors drivers gone bad. After I pulled out the connector of the PCM there was a Black oil like liquid inside. But I decided to purchase a refurbish PCM, I put it on today and the problem went away. I would advice to check injector, do the testing with a multimeter and the connection of the PCM. In my case it was that Black oil that probably damage that part of the PCM injector drivers and cause the P0206, Well it surely work for me, Thanks for that Video help me a lot on dismounting and mounting again engine parts. Miles on VAN is 173300 miles.
You're welcome. Cheers!
thanks dude, i was here looking for the gas line only and i found it thanks to you
Cheers!
Got an 06 Grand Caravan 3.8. Keep up the good instructional videos! Thanks.
ya for a guy like me who also likes Caravans you like to work on them like myself as I enjoy the way you explain ( For Entertainment Only)...... Keep up the good work,,,Cheers !
hey Steve great video I know a lot about cars and I do a lot of work on my van but your video was still helpful keep them coming thanks
A few complaints here: As long as we're going through all of this work to actually get to the fuel injectors, why not take the time to clean them out as well? Obviously, due to the costs of new fuel injectors, most poeple won't be replacing all of them at once. Usually, when one has failed, the others aren't far behind the failed injector.
Very good job explaining everything. Thank you
Your video helped. I changed everything was still having issue. The car was still shaking but running better.
Good video. Just pull the negative battery terminal next time. Power cant go anywhere without ground
Thanks for taking the guesswork out.
Awesome, pretty and understandable language for neophytes like me. Thank you!
Great video Steve. Thanks.
I think that by taking off the fuse of the fuel system you relieve the pressure . For most cars anyways good video helped a bit I took off the black trim for more room space but I have a 2000 so a little different
Taking the fuse for the fuel system out does NOTHING with the fuel pressure, on ANY vehicle. The fuel system fuse stops the pump from running and maintaining pressure, but it does nothing to relieve the pressure that is already there. In some cases, removing the pump fuse and then cranking the engine WILL relieve SOME of the fuel pressure, as the injectors will bleed off pressure when they are energized by the PCM during cranking. The best method is to do as Steve has shown and manually relieve the pressure. This is the correct method.
+Leonard Ratliff Actually removing the relay / fuse is EXACTLY what you are supposed to do. The way the author does it in the video is absolutely the wrong way to do it - from a safety perspective.
From the Chrysler FSM:
STANDARD PROCEDURE - FUEL SYSTEM
PRESSURE RELEASE PROCEDURE
(1) Remove Fuel Pump relay from Power Distribution
Center (PDC). For location of relay, refer to label
on underside of PDC cover.
(2) Start and run engine until it stalls.
(3) Attempt restarting engine until it will no
longer run.
(4) Turn ignition key to OFF position.
(5) Return fuel pump relay to PDC.
(6) One or more Diagnostic Trouble Codes (DTC’s)
may have been stored in PCM memory due to fuel
pump relay removal. The DRB IIIt scan tool must be
used to erase a DTC.

awesome video! will be watching this again when my parts arrives1
Good video. Did this fix your problem?
hey my friend i have a a 2002 caravan sport v6 that burns a lot of fuel and theres black smoke coming out the back and no check engine light, we replace de o2 sensor, air cleaner, spark plugs and can get it to run smooth can you help with any advise will be highly appreciated
The wiring harness on this series of vans had problems deteriorating inside, the outer cover should be opened to examine the wires inside. This problem occurred where this fi harness plugged into the main harness which is located to close to the exhaust crossover.
Great video. Have a problem with by number one plug and need to change that injector as I troubleshoot. Video will be a great help.
If one injector is bad, most likely rest are on their way out, on such old van I would just get a cheap Chinese set of injectors from ebay and replace them all
Thank you for your video, it was very helpful. Unfortunately for me it was my pcm that is not working. Had it confidence from two different mechanics.
same problem with my 99 caravan sport. Except it was an intermittent connection at one of the connectors. Fixed it with some dielectric grease. That was 30k miles ago. All is still working fine.
I think it's better to use lithium grease for plastic and/or rubber parts, other oils can dry up the rubber and make it crack over time. just something that I've seen in other videos. just an idea though!
good tip, thanks :)
thanks so much for making this video...it's proven very handy. may God bless you for your service.
would it be a good idea to change all the o-rings? Great video by the way.
In my case van began to run very rough and could barely keep it running by working the throttle. I know the catalytic converter was plugging and ordered a new one. I drove the van a few more miles, and the check engine light came on, van began to barely run. The Bat light came on, yet the alternator was putting out. Had Autozone check the alternator, check out OK. Day before no codes set. Rechecked after check engine light came on. Found 17 codes set, mostly low inputs and low 5v supply
Great video. Thanks for the attention to detail
Yah, the wire can be bad when wiggled or moved, so no surprise there. Thanks for the vid. Getting ready to do this same thing.
Great video - wish you had shown removing the plenum bolts on the REAR, And why would you not just replace all the injectors, since you had it all apart? They are cheap enough,. I agree, odd about the wire. I guess one should wiggle the wire while performing the test
Good work but dont u think would ov been beeter if u changed all ov the injectors
what are the odds of a new delphi fuel pump not working after being r&r? Van starts when i spray carb cleaner in the throttle body but does not get gas from tank or somewhere in between.
+Yeldarb Q new parts fail all the time. It's possible the pump is bad, did you check the fuel pump relay? plugged fuel filter is also possible
*****
i checked the relay with a couple wires to the battery and it is clicking lke it should. and I have a new fuel filter. just ont want to crawl around under it again. pump clicks but does not "wurrrrrr". thanks
Thanks I'm tackling it in morning
Nice. When it misses you can smell gas in the fuel.
Continuity test the harness from the end where it plugs into PCM make sure all injector wires power up and any that injector that doesn't power up then the PCM is the problem for sure Ebay sells the PCM but they require all your Vehicles info so they can Re-flash software to new PCM can work on your vehicle new PCM from EBAy around $150-$180 injectors are easy to clean with carburetor cleaner and saves money reusing old ones they are loads of VDOs on You tube to show how to clean Injectors hope this helps. I'm working on 99 V6 Camry Valve Cover Gaskets what a NightMare .
Excellent. Thank you for the video. I have seen that I need to find the fuel pump relay and pull that before I bleed the fuel rail. Did you do that or did you just bleed it? super helpful thank you sir.
My egr valve bolts is rusty looks like it never came off .. about of afraid 😟 to even try to turn it .. but if I can get pass those then the rest is easy
Thank you much! Very good @ explaining step by step and detailed. Enjoyed your video!
AWESOME video. Good God man! Great detail. You walk us through everything.
I changed my #2 injector on my 2002 grand caravan because the code said that it was bad and that the map sensor was bad...I changed the #2 injector and it still was spitting out gas...what should do next
Thanks for posting brother! Good on ya!
Off the subject question; What brand camera did you use for this video? it looks pretty HQ video! Thanks for sharing the repair!
Wow what a great job you did in this video ! I think I can do mine now!! Thanks
عمل ممتاز
💯👍🏼💯👍🏼

What do you think caused the wire harness to fail on these vehicles? Could back firing damage wire harness say if timing is off a little.
no, the heat of the engine and the wires getting too hot is the culprit, usually the harness melts where it wraps around the head.
Fantastic video ... and I have the same problem ... with injector 6 ... going to try access the wiring harness without pulling everything... if you are still following this thread, how far back from the injector was the break, or do you even know... Did you spice onto the wire at either end, or did you replace wire and connectors at either end... ? ? ? Well done... great video..
Thanks for your help.
Great video, and this definitely helps. Thank you for the video.
Cheers!
Just in case someone with a 3.0L Voyager/Caravan comes across this video, it is v.v.v.v.v.v. important that you replace all the fuel injector-to-fuel rail retainers whenever you service the injection system! Moreover, if you choose to install the yellow Ford Explorer injectors that are available for the Chrysler 3.0L motor, be sure to also install pintles on them because they dont come with them! I accidentally totaled my Plymouth Voyager last month due to fuel related fire, so I know better :[
If Ricky and Julian drove by in a monte carlo I wouldnt bat an eye(this is super Canadian). 😂
@LoriLucas-ub4hk that's funny..... the trailer park Boys don't live far from me cheers
just a subjestion u checked contuinity but what if it was grounding elsewhere at the same time i would recommend getting something such as a powerprobe to check for grounds with the harness off just to triple check and make sure u got no other shorts to geounds else where
Great advice! thank you. cheers!
Hi Steve and everyone that subscribes to his posts.I just bought a 1996 Dodge Caravan with the 3.0 liter SOHC V6 Mitsubishi. I just paid $285.00 to have the injector replace,but the engine is missing badly when I drive it. I am not a mechanicley inclined. What should I look at first? Thanks
wait... I was always taught you disconnect the negative terminal of the battery
It really doesn't matter, as long as you disconnect one of the two there will be no power from the battery. Usually I see the recommendation to disconnect the ground, but some believe the positive is better. Regardless, if either one is disconnected, electricity will not flow from the battery.
Thanks for the video amigo , great video very clear , I might be doing that tomorrow.
cheers
You are awesome....make it so easy to do it!
Thank you for this video, we took it all off easy and now are replacing all of the injectors. Three of the small little caps were broken so my question is can they be replaced ? Just the caps? and if so, how do we find them to buy?
I don't know if the caps are available by themselves. Cheers
Good video fellas this help me alot to replace my rail ,gracias , thank you
Great job, and good camera job, thanks
muy bien ... excelente video... gracias por publicarlo.
Also tested all the fuel injectors and cleaned it with carburetor fluid and test each one of them work with no problem so I know it's not the fuel injectors themselves
