I sure appreciate your knowledge & methodical approach to diagnosing & solving the various problems that come your way, you’re a true master-technician.
Thank you for this video. I have a 2007 Toyota Tundra 4.7 with 267k miles. My truck gave no symptoms for a failing fuel pump. I pulled the truck out of the driveway to work on my other vehicles. Then pulled it back into the driveway and let it keep running so I could add more freon to the ac. As soon has the hose was connected to the ac port, the truck shut off. Then it began to have a crank no start. Pulled out the fuses and relays, then placed them back in and truck started again. Then later drove it 10 miles and everything was fine. Then drove it the next day for another 10 miles and all was good. So then come Monday, drove the truck to get gas. Right when I drove up a small incline the truck shut off and it wouldn't start again. Had to tow it home. Replaced the fuses and rely and it didn't improve anything. So bought a new fuel pump from Rockauto. So after watching this video, I now feel confident about replacing the fuel pump. But I'm curious if it's important to wash out the gas tank before placing the new fuel pump in the tank? You didn't mention in your video about cleaning the gas tank.
So I just came across this video today. I’m sure you can guess why. It was around 9 am . I had this happen to my 2014 Toyota Tundra 1794 . She has 150,000, miles on the streets. It was not cheap 😢. I told the shop yeah .let’s get it running. Thanks for this video
BEEN A TOYOTA TECH FOR 21 YEARS. ABSOLUTLY RARE CASE. HE WOULDNT NEED A FUEL PUMP IF HE WOULD WATCH THE FUEL LEVEL. 2018 WITH 50K ON IT. THIS IS A WARRANTY PART FOR 7 YEAR 70000 MILES. FREE AT DEALER IF HE WOULD HAVE TOWED IT THERE. DIAGNOSIS WAS GOOD. GLAD CUSTOMER HAD TO PAY FOR HIS OWN MISTAKE.
Are you still a tech? I’ve been seeing the newer tacos having back fuel pumps and throwing codes for it. I even had a taco with a back fuel pump in the tank, replaced it and the new one was worse than the new old one. Took me 3 pumps to fix the issue.
Is their not a fuel pump shut off switch. I was thinking maybe when the pump went dry it'd shut itself off. They did on older cars I know. Both for when you ran out of gas or in an accident where the care may have overturned it'd shut off for safety.
Andrew Sims I don’t believe there is one. I’ve replaced my fair share of tundra gas tanks or cracked sending units and the wires going to the unit are for the pump to run and the fuel level. Also I’ve never been flat out told there’s a logic having low fuel in the tank and the wires for the fuel level go straight to the combination meter(speedometer)
Steve Smith It’s totally happens. It’s known but I don’t think it’s the most common thing in the world. I see about 50% of tundras coming in for service dry, 35% having a timing cover leak, the remaining 15% is the cam cradles/towers. Also another thing I’ve been noticing if a 5.7 liter tundra comes in with misfires I wouldn’t rule out the possibility a valve spring has broken. Again not super common but I’ve seen it enough I made a point to remember. I usually see our cars misfire due to poor fuel quality like too much ethanol content.
@@Trex6767 Just curious... Funny little story, I drove a Tacoma for a few years, then down graded to an f-150... Went to the parts store and just walked up to the counter and said "I need a thermostat"... The guy looked at me and said "what you driving?"... I said "oh, I forgot how to do this, I have been driving a Toyota for the last few years"... LOL
Owner probably ran his truck constantly with low fuel and just overheated that pump. Especially in hot 100 + weather. Keep some fuel in that tank. That goes for any Vehicle Manufacturer that uses an electric in tank pump
Raul Lazaro Fill up with a quarter left that’s what I do in my car I look at the quarter mark as empty that way my pump stays mostly covered in gas and it lasts longer. There’s not much to the pump it’ll last forever if you don’t run your tank low. Keep it above a quarter.
Ryan Scherbluk in cold climates and snowy areas never run your vehicle below 1/3 of a tank that way if you hit the ditch you can still idle for a while, for example a Subaru Outback can idle for 30 ish hours on a full tank of fuel before running out, that 30 plus hours buys you time
Great walk through of your diagnostic technique. Need more mechanics like you. gauge on empty indicates that this truck has probably spend a lot of time on super low level. Still kind of crazy that at only 58k it needed a fuel pump. I guess they just don't make them like they use to.
Great diagnostic process walk through. I believe there was a recall recently on this year fuel pump on multiple models including tundra. Customer may be able to get reimbursed for labor and materials from Toyota.
Excellent video! Fuel pumps have been a problem for all toyo/lexus vehicles since the introduction of their "flex fuel" models, even if you never use flex fuel. Something about the ECM measuring the alcohol content incorrectly and responding poorly with the pump ECU and fuel pump that results in struggled cold starts and hard shifts while warming up, and ultimately a dying fuel pump. They don't have a replacement part than the Delphi FE0707 currently, so I purchased an aftermarket aeromotive pump with higher flow capabilities that folks use when supercharging (haven't seen any with issues after upgrading). I'll be wiring it into the existing pump assembly this weekend and praying that makes this truck purr again. Don't buy flex fuel models!!!!!!!!!
I have this same problem. Had the pump replaced and alcohol reset and 3 years later the ethanol was reading was back at 74%. Had to reset with techstream and right back to starting and running smooth as ever
Hard to imagine pump gone so soon. Things do break! Nice logical step by step diagnosis. Moment of truth start up always scary when doesn't fire up right away! Great video!
@@ADVANCEDLEVELAUTO There is still wiring integrity to check that you didn't show. I know a lot of technicians would not do that final step because it is not usual for wire to break but assume there were rodents in there and could have nicked the wire or even a small internal corrosion. I have seen the craziest things with wires that have intermittent connections and ends up that they just have a string that is still making it work intermittently. I have seen this in modules and sliding door from minivans.
I have a 2015 Tundra SR5 double cab with the 5.7 litre Trd off road package with about 55 thousand miles and so far no issues other than having a rear seatbelt repositioned because it would get sucked into the seat when lowering or raising seat. I am curious does this truck not still have the bumper to bumper warranty. Good video of explaining your process of elimination.
I live in Dallas. And I had enough this year of the heat. The humidity today was brutal... 1 more week...And running vehicles low on gas to many times will burn them pumps out quick..
@@nightfangs2910 I can tell you this. The Ford E-250 cost $350.00 at the dealer. Then $200.00 for me to replace them. As the owner of catering shop has replace his 4 times. As his employees run out of gas all the time. And it only takes 2-3 times and they will say good bye! Least it's empty when I have to drop the tank. Takes me 30 mins to change it now.
Man, dont say that. I just moved to Dallas 4 weeks ago and so far the weather's been amazing. But, I know it's coming. However, I came from the swamp in Louisiana and there's NO WAY you guys have that kind of humidity. Not even close.
Nice video. 👍🏼 I’m trying to troubleshoot my 4th gen 4Runner that when I try to start doesn’t, but when I turn the key to start, continues to crank even if you let go of the key. Then I need to turn the key to the off position to get the starter to stop. Any thoughts? Ignition switch, ignition, starter ???
It is under the powertrain warranty. 60months/60,000 miles. But it look as though, as many have suggested, the owner deliberately ran it on low fuel, in turn killing the pump. So, really it shouldn't because the owner, if true, were carless and at fault. Not a faulty fuel pump. Therefore, the owner shell out for the repair.
Curtis Fleabag ehhh i have owned several toyotas and bot had these issues, however toyota isnt AS PERFECT as ppl think i had a 2011 camry and water pump was replaced twice in 4yrs (once before i bought it according to service records, and once 2yrs later,,)
@Curtis Fleabag tell that to the 01 tacoma my grandfather just sold with 500k plus miles. Never had any problems aside from someone hitting his radiator and waterpump with a haybale fork.
Trenton Archer · Tacomas are dependable little beasts 😊. I am making payments on my 08 tacoma access cab 4 cyl. truck. It's only got 61,600 miles on it. Am so glad i found it. It was the only one left in the dealership. Probably owned by an older person. The only thing i can think of adding. Is reinforcing the back with stronger leaf springs and installing Bilstein gas shocks. That's it 💪😅
All these people saying it was run low on fuel too much, just remember, when the tundra low fuel light comes on it still has over 6.5 gallons left! Plenty to cool itself. It’s just a bad pump-no need to try and explain why.
If that is the case, a faulty pump, it would be covered under the powertrain warranty. The owner could have gotten it towed to toyota for the repair. Unless the owner kept running it lower, til completely out. Who knows?
Eric, really enjoyable to watch and excellent thought process and some time what i do to check pressure i hook a loop in state of pump fuse and read the amps on the amp meter so every one amp equal 10 psi so 5 amp = 50 psi cheeeeeers and thank you for sharing.
when you were checking the fuel pressure at the red piece, how do you remove that piece from the line? Does it just pull out or is there a clip you need to lift?
what do you use to seal the wires after probing them? Ive had my power probe for close to 15 years now, I need to upgrade to one like yours with a readout, Thanks for the video
This video is detailed and explanatory, I like it. Thanks. Is there a way to know from the odometer if the fuel pump is defective when the key is turned on just to avoid the detailed and long process test and diagnosis. I have a 2006 Toyota Highlander that is doing the exact same thing that this Tundra is doing. Hope I can get a clue from you to get it fixed.
Similar problem with my 2004 Toyota Tacoma 4X4 4 cylinder, automatic. I'm the original owner. 70,000 miles. Well maintained all by me and garage kept. Looks and runs like new. Full tank. For the third time, it won't start. Really strange since it's the only time I have ever heard it crank since as soon as you hit the key, it starts. The first time, it made just a little microsecond like it was starting and then just cranking like crazy. Three or four tries. No deal. Figure I must have flooded it. Came back later and it started. This was couple years ago. Now it has done it twice more. Once warm and I had turned it off not 10 minutes picking up a few items. It started on the 4th try. A few days later, cold, did it again and it would not start after a few tries. Cranking like crazy. (Good Max Everstart battery) Checked for codes with blue reader. One on rear heated oxygen sensor stored (Only mechanical repair I have ever made and that was due to the heater burnt out on that oxygen sensor.) No other codes. Cleared it. The truck started after the reader ran and did not repeat the code. I swapped the power outlet relay with the same EFI relay in the engine compartment after I checked both relays. I added a grounded spark plug on top of the valve cover so I can pull the number one coil pack off the engine spark plug to check for spark next time. Note on the vehicle that there is no fuel pump timer to charge up fuel pressure like some cars. What is even worst is you can't even hear fuel pump with a full tank. The EFI relay drives the Circuit opening relay in crank mode. Once running, the ECM sees that from the crank position sensor and then grounds the coil on the circuit opening relay in the on position then and only then. I checked the circuit open relay under the dash that is power by the ECM. Even jumped it there and that is when I realized you cannot hear the pump as a check. I did attach a wire to the relay tank wire side. Now I can attach my meter to that and ground. I can key on and see no voltage. Crank and it becomes 12.7 or so. Starts and let off starter at key on and see the 14.2 or so running motor charge. What is my problem? It's so hard to catch. By my self. The 70,000 is 95% city. Has all the red lights in the city actually put 200,000 miles on fuel pump and it's brush is almost worn out and occasionally pump is not running? Is it the ignition switch? Both these are a pain to just guess at. Has original filter tucked up under intake runners on it. I have a replacement. I don't think it's that since it runs like new all the rest of the time. Thoughts. Biggest problem is I just don't trust it at my age.
This channel is gonna grow, you deliver excellent diagnostics, quality videos, thoughtful dialogue, and you don't waste viewers' time. I will work through past videos. My first thought was why not use a high amp bulb to check wiring with pump disconnected. Now that I think about it, if the pump was good your technique PROVES no line resistance, because otherwise there would have been a voltage drop on either the ground or voltage side. After all, assuming the pump is good, you were doing a drop test across the energized pump, electrons were flowing during the test. However if the pump was bad AND wiring was bad, then you might not see a drop. Two coincident problems are unlikely and you saved a step. It would have been interesting to see current but there isn't much room for satisfying curiosity in a working shop.
Thank you! Yes, I did what I could with the time I had and the fact that I could not gain access to the pump without dropping the tank. The module was doing it's job providing power and ground for the pump on command, so I felt comfortable calling a bad pump. Thanks for watching! btw I just subbed to your channel! I'm looking forward to checking it out!
Key on and no fuel pump priming sound, then it's a bad fuel pump. Takes 2 seconds to diagnose. However a very good step by step assessment and very clear instructions.
Its always good to check relays and make sure it has power before dropping the tank. You’d look like an idiot replacing a 300 dollar fuel pump when it turned out to be a bad relay. One thing i learned doing this is never assume you know exactly what the problem is because you think you're a badass.
This is a very good video highlighting the t-shooting process. Always check and eliminate potential causes. Too many idiots i worked with would be too quick to assume its this or that without actually doing what you did.
nice diag but you really need a better piercing probe. a guy could drive a mack thu the holes that made. personally i hate piercing but i do understand the need at times.
Liked the video. I have a 2009 Toyota Tacoma which has a slow crank and a click but no start. Sometimes it starts on the first turn and other times it takes about four to five turns of the key. Battery terminals are clean, new battery, swapped out starter relay with horn relay and still has the same symptoms. What am I missing?
My first time on your channel. I thank you for all your info on this Toyota. I have a 1996 Toyota 4 runner that may have this issue. It isn't turning over when I turn the key. Might be the fuel pump but I know it was replaced. Thank you for all the info. Thumbs up on your video. After doing some checking i will give feedback on my vehicle.
I had three new fuel pumps put on, the most recent one a OEM, had pressure check done, electric test done, fuel system clean out done, reflash as well. My truck still cranks and will start after waiting 20 minutes, then I will restart it several times and it will start, then I will shut it off and it will crank and not start then I wait another 20 minutes or so and it will start again. I put a new ignition switch in, checked all the fuses none blown, I thought maybe the Crank Position Sensor, what are your thoughts?
I have the same problem, kinda. Replaced the Fuel Pump. filter and fuel pump sleeve. Still wont start, but when i turn the key on, no check engine light. No fire, nothing. I am thinking that I have a bad sensor somewhere, and i am waiting on my tundra book wiring diagram to come in so i can run it down. Also, i have a 2001 Tundra 4.7. 391k miles, first problem i had with this truck. I MISS MY BABY!!!
Excellent video, mine cranks like that, but starts..I recently took the battery out to test it, maybe I took the battery out incorrectly, is there a right or wrong way?
I’ve used a external 12v fuel pump and gas in a bucket to start a no start. You ever try it? Kinda of a fuel pump bypass. What’s the warranty on Toyota 36 mo? Bummer
good video yu should do more of these one question 1996 mitsubishi Pajero crank not starting change crank sensor not getting any sparks . how can yu assist
I loved your video. The only thing I didn't like is piercing the wires and not probing the connector. That will help rot out the wire over time if it ever see's salt from the road or beach. Hope you protected the holes you made in the insulation? You did great on the diagnostics!!
Always go after the relay after the fuse, this tech knows his stuff. My 2021 tacoma also had a bad relay from week 2 of owning it, brand new relay had thick carbon buildup. Not a problem after I replaced it with the gray a/c relay and now it has 9000 miles on it. I think the blue relays are made cheap compared to the gray or purple. Don’t use the purple one tho it uses 140mA, gray/blue are 75mA.
something is fishy here..im a Tundra owner since 2004 , bought my second 3rd gen in 2013 , watching like a hawk vids related to issues and I can confirm that this is a first to see this type of issue the last 15 years or so that im aware of ..very odd I would say ..something doesn't add up since this trucks are built to last 1000000miles
I don't want to burst your bubble... But 100,000 miles? Not as realible as u think they are... Especially the issues with these 5.7 all over the place not the first time I've seen these pumps burn out so quick... We've done 3 already this year. That tundra with the 4.7 was pretty good.. Except the timing belt is
Quick question.. my son has a 2008 Tundra with a 4.7 v8, same issue, we've replaced the fuel pump and still wont start. It will start when cold, but drive it for a little while shut it off, then it acts exactly like the truck in this video.. would you look at the fuel pump control module next? I had a parts counter guy, I know not a mechanic, say it sounded like a mouse maybe chewed a wire and it has a short. Just looking for a little guidance. Thanks
Yea that's what I was getting at between GM's and Dodges variadable valves which was a failed venture by the two late 70s into the 80s still is Ford's eco poops and plastic oil pans the" big 3 "do not hold a flame to Toyota for sure.
@@johnpowell5181 atleast chevys are cheap to fix though and I guess gm also, I've never owned one. My step dads ford f150 has had issues with its turbo more times than it's worth driving the truck sadly.
06 tundra 195k miles had intermittent crank no start problems. Usually started on second or third try. Then 8 or 9 attempts without start. New battery same.. removed and reinstalled all fuel and efi relays, then did a drum solo on all relays. Has been starting flawlessly for a few days now. Gonna replace all associated relays. Hope this helps.
Why crank starter, when the pump starts at ON position. Unless it's mechanical pump. I've run my landcruiser and Camry passed the E line and never have had fuel pump problems.
Great video bro appreciate. I have a ? . I have a 2015 tundra it’s acting up only in the mornings or after sitting for a few hours . It cranks fine but revs up slowly like the fuel takes time to go thru . What you think is going on ?
Dude.... the fuel tank was dry when it came in. The owner burned the pump up running the tank low. I have 2 tundras, a 2000 and a 2010. The 2000 has 140k with the original pump and the 2010 has a 46gal tank with a flex fuel pump from McGeorge toyota. Always stick with toyota parts.... aisin and denso. And keep the fuel tank full-ish. It keeps the pump cool and lubricated.
I have a 2008 Toyota tundra and parked at idles great put it in drive and it idles high and when you come to a stop and you let off the break ready to accelerate on his own how to fix or what could be the problem no engine light on no codes Thank you in advance for your input
Apparently I ran out of fuel on my 2008 Tundra. Running down the road and suddenly died while showing a little less than a quarter of a tank left or 50 miles. Pulled over and tried to start but failed twice. Got fuel in it and it started up right off the bat. Should I be concerned of fuel pump failing down the road or just fill up tank at half tank mark? Any suggested onboard tests or fuel tests diagnostics that can be done?
Please tell me you used liquid electric tape where you pierced those wires. If you didnt that thing will be back with fuel pump trouble because those wires corroded in 2 where you pierced them.
I run my tundra to gas light often have 108k on it and it's still perfect. The fuel sender holds fuel in a basin for cooling the pump that's always there even if you run the tank completely empty. I'd say just a faulty pump it happens sometimes with mass produced products some last forever some just go bad 🤷♂️
My 2016 Tundra cranks without starting several times first thing in the morning. Usually starts the third time. do you think that the fuel pump could be going bad? Once it starts it runs and starts all day. Thanks
why did not show rpm signal on the scanner DATA PID during cranking, first thing I would think is if the pcm does not see rpm would not activate the pump mere than key on for 2 seconds.
yonda ila yes you are right, this is a Japanese shit... fuel pump breakdown because fuel is low in the tank, well that’s the weirdest and funniest reason I ever heard 😂😂😂 If you want a real truck, get an american one, go to the source and where story started...
hi eric ,i think you've made a video like this one on a toyota tondra befor ,actualy sice that time a question make my mind busy, could it be possible to turn this system(PWM fuel pump controled) with just ON/OFF system. i mean a least when the fuel pump pwm unit is faulty and no access with brand new. REGARDS.
Christopher magee · Every once in a while fill the tank with 93 octane. Don't just keep on buying the same 87 octane gas. Also every 2 months dump a bottle of fuel system cleaner. This will help maintain the system and the fuel pump run smoother and last longer. If you just keep on putting in the cheap 87 octane. Sure it's cheap. But you will probably pay for it when you least expected 🤔. Yes you also have to try and keep the tank a little above a quarter of tank filled. The gas their selling these days. Tends to be more volatile. I guess too much ethanol or alcohol beeing mixed in with the gas maybe allowed by the owners of the gas station. You don't see any inspectors looking into that part of the problem😔
My gas pump was changed for 2010 Tundra SR5. The fuel gauge is now not reading properly. It showed half a tank, but truck turned off and had to put fuel. Whenever a gas pump is changed, do you need to reset the gas guage?

Great video. I learned a good amount. This guy clearly knows his way around a vehicle.
probably burned out the pump by letting the fuel get to low ( fuel needed to lubricate the pump)
My thoughts exactly. Thanks for watching!

@@bigdaddymak1439 I was going to say the same thing as well
@@elevatorman427 yeah running it out probably didn't kill it but cranking it over and over empty before sending it to the shop did

@@nightfangs2910 I can tell you this. The Ford E-250 cost $350.00 at the dealer. Then $200.00 for me to replace them. As the owner of catering shop has replace his 4 times. As his employees run out of gas all the time. And it only takes 2-3 times and they will say good bye! Least it's empty when I have to drop the tank. Takes me 30 mins to change it now.
Man, dont say that. I just moved to Dallas 4 weeks ago and so far the weather's been amazing. But, I know it's coming. However, I came from the swamp in Louisiana and there's NO WAY you guys have that kind of humidity. Not even close.

I'm a weekend mechanics, but from the first crank. Already knew has a bad Fuel pump. But still excellent diagnose to make sure it fuel pump.
Mota 0116 no you didn’t
clark garber ?
Bruh I said the same thing to myself. I understand having to take baby steps to be sure but I would have went straight to the pump.
Nice video. 👍🏼
I’m trying to troubleshoot my 4th gen 4Runner that when I try to start doesn’t, but when I turn the key to start, continues to crank even if you let go of the key. Then I need to turn the key to the off position to get the starter to stop. Any thoughts?
Ignition switch, ignition, starter ???
Isn't it still under manufacture warranty?
It is under the powertrain warranty. 60months/60,000 miles. But it look as though, as many have suggested, the owner deliberately ran it on low fuel, in turn killing the pump. So, really it shouldn't because the owner, if true, were carless and at fault. Not a faulty fuel pump. Therefore, the owner shell out for the repair.
Curtis Fleabag ehhh i have owned several toyotas and bot had these issues, however toyota isnt AS PERFECT as ppl think i had a 2011 camry and water pump was replaced twice in 4yrs (once before i bought it according to service records, and once 2yrs later,,)
That’s exactly what I was thinking 🤔
@Curtis Fleabag tell that to the 01 tacoma my grandfather just sold with 500k plus miles. Never had any problems aside from someone hitting his radiator and waterpump with a haybale fork.
Trenton Archer · Tacomas are dependable little beasts 😊. I am making payments on my 08 tacoma access cab 4 cyl. truck. It's only got 61,600 miles on it. Am so glad i found it. It was the only one left in the dealership. Probably owned by an older person. The only thing i can think of adding. Is reinforcing the back with stronger leaf springs and installing Bilstein gas shocks. That's it 💪😅
Excellent troubleshooting process ! Wouldn’t mind taking my cars in there for a check up🤙🏽
Hey Erick. What software or website do you use to pull the diagrams? Thanks
Excellent job of troubleshooting this sir.
All these people saying it was run low on fuel too much, just remember, when the tundra low fuel light comes on it still has over 6.5 gallons left! Plenty to cool itself. It’s just a bad pump-no need to try and explain why.
If that is the case, a faulty pump, it would be covered under the powertrain warranty. The owner could have gotten it towed to toyota for the repair. Unless the owner kept running it lower, til completely out. Who knows?
Do fuel pumps fall under powertrain? Either way, I would have tried the dealership due to its young age.
@@wsmcook sure does. You can download the warranties manual directly from toyota website.
So he had about 8 miles to empty
@@johnw391 must be a part made in USA. I have been working on Japanese cars since I was a kid and all of the pumps I had is still made in Japan.
Eric, really enjoyable to watch and excellent thought process and some time what i do to check pressure i hook a loop in state of pump fuse and read the amps on the amp meter so every one amp equal 10 psi so 5 amp = 50 psi cheeeeeers and thank you for sharing.
Excellent video. Very helpful troubleshooting my issue with my 2013 Sequioa.
I enjoy to watch the video,that's a proper diagnose,, salute sir ,🎉
You handled that pretty well. Great diag. Thanks for sharing 👍
Thank you!
Nice to know video! Why did you choose the fuel line connector in the back and not the one closes to the front?
when you were checking the fuel pressure at the red piece, how do you remove that piece from the line? Does it just pull out or is there a clip you need to lift?
what do you use to seal the wires after probing them? Ive had my power probe for close to 15 years now, I need to upgrade to one like yours with a readout, Thanks for the video

Buen videos disculpe una pregunta Chevy silberado 4.8 oh 5.3 cual recomienda
You're the best!! This trouble shooting process worked like magic. THANK YOU!!!!
This video is detailed and explanatory, I like it. Thanks. Is there a way to know from the odometer if the fuel pump is defective when the key is turned on just to avoid the detailed and long process test and diagnosis. I have a 2006 Toyota Highlander that is doing the exact same thing that this Tundra is doing. Hope I can get a clue from you to get it fixed.
Similar problem with my 2004 Toyota Tacoma 4X4 4 cylinder, automatic. I'm the original owner. 70,000 miles. Well maintained all by me and garage kept. Looks and runs like new. Full tank. For the third time, it won't start. Really strange since it's the only time I have ever heard it crank since as soon as you hit the key, it starts.
The first time, it made just a little microsecond like it was starting and then just cranking like crazy. Three or four tries. No deal. Figure I must have flooded it. Came back later and it started.
This was couple years ago. Now it has done it twice more. Once warm and I had turned it off not 10 minutes picking up a few items. It started on the 4th try. A few days later, cold, did it again and it would not start after a few tries. Cranking like crazy. (Good Max Everstart battery)
Checked for codes with blue reader. One on rear heated oxygen sensor stored (Only mechanical repair I have ever made and that was due to the heater burnt out on that oxygen sensor.) No other codes. Cleared it. The truck started after the reader ran and did not repeat the code.
I swapped the power outlet relay with the same EFI relay in the engine compartment after I checked both relays. I added a grounded spark plug on top of the valve cover so I can pull the number one coil pack off the engine spark plug to check for spark next time.
Note on the vehicle that there is no fuel pump timer to charge up fuel pressure like some cars. What is even worst is you can't even hear fuel pump with a full tank. The EFI relay drives the Circuit opening relay in crank mode. Once running, the ECM sees that from the crank position sensor and then grounds the coil on the circuit opening relay in the on position then and only then.
I checked the circuit open relay under the dash that is power by the ECM. Even jumped it there and that is when I realized you cannot hear the pump as a check. I did attach a wire to the relay tank wire side. Now I can attach my meter to that and ground. I can key on and see no voltage. Crank and it becomes 12.7 or so. Starts and let off starter at key on and see the 14.2 or so running motor charge.
What is my problem? It's so hard to catch. By my self. The 70,000 is 95% city. Has all the red lights in the city actually put 200,000 miles on fuel pump and it's brush is almost worn out and occasionally pump is not running? Is it the ignition switch? Both these are a pain to just guess at. Has original filter tucked up under intake runners on it. I have a replacement. I don't think it's that since it runs like new all the rest of the time.
Thoughts. Biggest problem is I just don't trust it at my age.
Great video, how does that fuel disconnect come off? I tried to take mine off and don’t want to break it. Thank you
This channel is gonna grow, you deliver excellent diagnostics, quality videos, thoughtful dialogue, and you don't waste viewers' time. I will work through past videos. My first thought was why not use a high amp bulb to check wiring with pump disconnected. Now that I think about it, if the pump was good your technique PROVES no line resistance, because otherwise there would have been a voltage drop on either the ground or voltage side. After all, assuming the pump is good, you were doing a drop test across the energized pump, electrons were flowing during the test. However if the pump was bad AND wiring was bad, then you might not see a drop. Two coincident problems are unlikely and you saved a step. It would have been interesting to see current but there isn't much room for satisfying curiosity in a working shop.
Thank you! Yes, I did what I could with the time I had and the fact that I could not gain access to the pump without dropping the tank. The module was doing it's job providing power and ground for the pump on command, so I felt comfortable calling a bad pump. Thanks for watching! btw I just subbed to your channel! I'm looking forward to checking it out!
You guys really deserve to be advanced level. Thank you.
Post mortem bench test/analysis of old fuel pump would be interesting. What exactly failed within the pump assembly?
Concise and very comprehensive video, good job.
GOOD TEST PROCEDURE , NEXT TIME YOU MIGHT WANT TO HAVE A JUG AT THE FUEL RAIL LINE TO CATCH ANY FUEL AND THANKS FOR THE VIDEO !
Yeah, but I was pretty sure that no fuel would come out after I disconnected the line and there was no residual pressure. Thanks for watching!
Key on and no fuel pump priming sound, then it's a bad fuel pump.
Takes 2 seconds to diagnose. However a very good step by step assessment and very clear instructions.
Its always good to check relays and make sure it has power before dropping the tank.
You’d look like an idiot replacing a 300 dollar fuel pump when it turned out to be a bad relay.
One thing i learned doing this is never assume you know exactly what the problem is because you think you're a badass.
Toyota fuel pump turn on , On crank not on acc
The fuel also acts as a coolant for the pump, so don't let the fuel level get too low.
This is a very good video highlighting the t-shooting process.
Always check and eliminate potential causes. Too many idiots i worked with would be too quick to assume its this or that without actually doing what you did.
nice diag but you really need a better piercing probe. a guy could drive a mack thu the holes that made. personally i hate piercing but i do understand the need at times.
I do use liquid electrical tape on them after. Thanks for watching!
Good investigation! Toyota’s have gasoline cooled fuel pumps and they could overheat if driven while gauge is reading “E”
Liked the video. I have a 2009 Toyota Tacoma which has a slow crank and a click but no start. Sometimes it starts on the first turn and other times it takes about four to five turns of the key. Battery terminals are clean, new battery, swapped out starter relay with horn relay and still has the same symptoms. What am I missing?
Cool video. You really know your stuff. Very impressive. That was text book trouble shooting.
My first time on your channel. I thank you for all your info on this Toyota. I have a 1996 Toyota 4 runner that may have this issue. It isn't turning over when I turn the key. Might be the fuel pump but I know it was replaced. Thank you for all the info. Thumbs up on your video. After doing some checking i will give feedback on my vehicle.
U find you problem I have similar problem on my 2004 Tacoma can u check my video
I had three new fuel pumps put on, the most recent one a OEM, had pressure check done, electric test done, fuel system clean out done, reflash as well. My truck still cranks and will start after waiting 20 minutes, then I will restart it several times and it will start, then I will shut it off and it will crank and not start then I wait another 20 minutes or so and it will start again. I put a new ignition switch in, checked all the fuses none blown, I thought maybe the Crank Position Sensor, what are your thoughts?
I have the same problem, kinda. Replaced the Fuel Pump. filter and fuel pump sleeve. Still wont start, but when i turn the key on, no check engine light. No fire, nothing. I am thinking that I have a bad sensor somewhere, and i am waiting on my tundra book wiring diagram to come in so i can run it down.
Also, i have a 2001 Tundra 4.7. 391k miles, first problem i had with this truck. I MISS MY BABY!!!
Excellent video, mine cranks like that, but starts..I recently took the battery out to test it, maybe I took the battery out incorrectly, is there a right or wrong way?
I’ve used a external 12v fuel pump and gas in a bucket to start a no start. You ever try it? Kinda of a fuel pump bypass. What’s the warranty on Toyota 36 mo? Bummer
great video on what steps to take and not just assume a bad pump from the start.
Wouldn’t this be covered under warranty? Why on earth didn’t they take it to a Toyota dealership?
Charles N Charge 3/36 I believe so no
Charles N Charge I was about to post the same question. Never mind, the car is out of warranty.
6 years 60K mile power train warranty. It covers anything fuel or oil touches. Including the fuel pump.
because the dealership will rip you off
good video yu should do more of these one question 1996 mitsubishi Pajero crank not starting change crank sensor not getting any sparks . how can yu assist
Thank you for the video! I have a 2017 tundra and it's doing the same thing.
Good job bro,my question is have you ever come across Toyotas with faulty smart key system not working? mostly land cruiser 200 series.
I loved your video. The only thing I didn't like is piercing the wires and not probing the connector. That will help rot out the wire over time if it ever see's salt from the road or beach. Hope you protected the holes you made in the insulation? You did great on the diagnostics!!
I sealed it back up with liquid electrical tape. Thanks for watching!
Back probe with t pins and wrap up so they won't short. Win win.
Always go after the relay after the fuse, this tech knows his stuff. My 2021 tacoma also had a bad relay from week 2 of owning it, brand new relay had thick carbon buildup. Not a problem after I replaced it with the gray a/c relay and now it has 9000 miles on it. I think the blue relays are made cheap compared to the gray or purple. Don’t use the purple one tho it uses 140mA, gray/blue are 75mA.
🤔.. how would you know if it had a bad fuel pump module?
something is fishy here..im a Tundra owner since 2004 , bought my second 3rd gen in 2013 , watching like a hawk vids related to issues and I can confirm that this is a first to see this type of issue the last 15 years or so that im aware of ..very odd I would say ..something doesn't add up since this trucks are built to last 1000000miles
It was run out of gas and the idiot owner kept trying to crank it and burnt out the pump .pumps need the gas for cooling.
I have never changed a Toyota fuel pump in my whole career of 39 years.
@@montefiveforty1 obviously you got lucky and never encountered a idiot Toyota driver
I don't want to burst your bubble... But 100,000 miles? Not as realible as u think they are...

Quick question.. my son has a 2008 Tundra with a 4.7 v8, same issue, we've replaced the fuel pump and still wont start. It will start when cold, but drive it for a little while shut it off, then it acts exactly like the truck in this video.. would you look at the fuel pump control module next? I had a parts counter guy, I know not a mechanic, say it sounded like a mouse maybe chewed a wire and it has a short. Just looking for a little guidance. Thanks
Maybe a little starter fluid short cut
juwee khan exactly
Do you guys don't think that might blow up the intake that happens to my friend 😂
Wow! That’s a big works!! But succeeds 👍👍👍
That’s a bummer. But I love the tundra. It’s a lovely truck with that 5.7 v8. When straight piped, this thing sounds amazong
Better to be fuel pump then something major to many engines and transmission failures at these miles these days
Not for toyotos though especially their trucks, the engines are very reliable. Your fords would have the problem and cheap chryslers
Yea that's what I was getting at between GM's and Dodges variadable valves which was a failed venture by the two late 70s into the 80s still is Ford's eco poops and plastic oil pans the" big 3 "do not hold a flame to Toyota for sure.
@@johnpowell5181 atleast chevys are cheap to fix though and I guess gm also, I've never owned one. My step dads ford f150 has had issues with its turbo more times than it's worth driving the truck sadly.
06 tundra 195k miles had intermittent crank no start problems. Usually started on second or third try. Then 8 or 9 attempts without start. New battery same.. removed and reinstalled all fuel and efi relays, then did a drum solo on all relays. Has been starting flawlessly for a few days now. Gonna replace all associated relays. Hope this helps.
Why crank starter, when the pump starts at ON position. Unless it's mechanical pump.
I've run my landcruiser and Camry passed the E line and never have had fuel pump problems.
What about the piercing of the wiring. Does that get repaired too?
Yes! Thanks for watching!
@@ADVANCEDLEVELAUTO have you ever heard of Buick Engines
Great video bro appreciate. I have a ? . I have a 2015 tundra it’s acting up only in the mornings or after sitting for a few hours . It cranks fine but revs up slowly like the fuel takes time to go thru . What you think is going on ?
Dude.... the fuel tank was dry when it came in. The owner burned the pump up running the tank low.
I have 2 tundras, a 2000 and a 2010. The 2000 has 140k with the original pump and the 2010 has a 46gal tank with a flex fuel pump from McGeorge toyota. Always stick with toyota parts.... aisin and denso. And keep the fuel tank full-ish. It keeps the pump cool and lubricated.
Tank you very clear and technically well presented thank you
I appreciate your work
I have a 2008 Toyota tundra and parked at idles great put it in drive and it idles high and when you come to a stop and you let off the break ready to accelerate on his own how to fix or what could be the problem no engine light on no codes
Thank you in advance for your input
Thank you for the video. Very informative. Having the same problem.
Apparently I ran out of fuel on my 2008 Tundra. Running down the road and suddenly died while showing a little less than a quarter of a tank left or 50 miles. Pulled over and tried to start but failed twice. Got fuel in it and it started up right off the bat. Should I be concerned of fuel pump failing down the road or just fill up tank at half tank mark? Any suggested onboard tests or fuel tests diagnostics that can be done?
Please tell me you used liquid electric tape where you pierced those wires. If you didnt that thing will be back with fuel pump trouble because those wires corroded in 2 where you pierced them.
I run my tundra to gas light often have 108k on it and it's still perfect. The fuel sender holds fuel in a basin for cooling the pump that's always there even if you run the tank completely empty. I'd say just a faulty pump it happens sometimes with mass produced products some last forever some just go bad 🤷♂️
Watching from NEW ZEALAND bro
What do you use to seal the pierce in the wires
My 2016 Tundra cranks without starting several times first thing in the morning. Usually starts the third time. do you think that the fuel pump could be going bad? Once it starts it runs and starts all day. Thanks
I know this is older, but as a tech I was wondering if you checked directly at the pump before dropping the tank?
Wow that sucks for the owner. No warranty. Awesome job finding out the problem.
Thanks!
Great vid man! You're diagnosing skills are skills are supreme. Just subscribed hope to see more vids soon
why did not show rpm signal on the scanner DATA PID during cranking, first thing I would think is if the pcm does not see rpm would not activate the pump mere than key on for 2 seconds.
Should the fuel filter be checked also, the break buster be checked with a fuel spray.
The owner killed the fuel pump. He clearly ran the car on low fuel, and probably often. 🤦🏾♀️
Japanese junk
yonda ila yes you are right, this is a Japanese shit... fuel pump breakdown because fuel is low in the tank, well that’s the weirdest and funniest reason I ever heard 😂😂😂
If you want a real truck, get an american one, go to the source and where story started...
yes all 58K miles. every time before fill up
U should never let the car on very low fuel, most time it’s just the owner being the idiot
@@Yondaily If it was a Ford, Chevy or Dodge, you would need a whole new engine and transmission, so calm down.

bro Toyota pump runs for 20 years straight, I dont know what you did to your Tundra
Ahmed Abdalla this isn’t his truck, he said a guy who owns an electric company near his shop owns it.
there are a couple of bad batch of pumps that found their way into a bunch of Toyota models. Toyota did a recall to fix these pumps.
My lexus is pretty much doing these same issues I see everyone else having with Toyota/ lexus
Christopher magee · Every once in a while fill the tank with 93 octane. Don't just keep on buying the same 87 octane gas. Also every 2 months dump a bottle of fuel system cleaner. This will help maintain the system and the fuel pump run smoother and last longer. If you just keep on putting in the cheap 87 octane. Sure it's cheap. But you will probably pay for it when you least expected 🤔. Yes you also have to try and keep the tank a little above a quarter of tank filled. The gas their selling these days. Tends to be more volatile. I guess too much ethanol or alcohol beeing mixed in with the gas maybe allowed by the owners of the gas station. You don't see any inspectors looking into that part of the problem😔
Did you have to reset fuel/alcohol percentage?
NEVER DRIVE YOUR VEHICLES ON EMPTY!!! The fuel pump needs gas to keep the fuel pump cool. My rule of thumb is fuel up to fuel up at 1/4 line.
My gas pump was changed for 2010 Tundra SR5. The fuel gauge is now not reading properly. It showed half a tank, but truck turned off and had to put fuel. Whenever a gas pump is changed, do you need to reset the gas guage?
What if the tachometer did move? What would be your next move?
3:33 the tiny scan tool beep noise is so adorable AHAAHAHAHAHHAAHA
Oh snap. Didnt realize you guys are in Houston. My shop is in Spring / Tomball / Woodlands area.
2010 Tundra same problem, but does have a strong gas smell. Should that change diagnosis?
