TOYOTA TUNDRA CRANKS BUT NO START

Today I had a 2018 Toyota Tundra 5.7 pick up truck towed into my shop. The engine cranks and turns over but will not start or run. In this video I guide you through my diagnostic and troubleshooting procedures used to determine the problem with the vehicle. In this case the fuel pump was bad, but these procedures can also help determine other problems. Hopefully you find this video useful or at least find it entertaining!

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.

[@unclemarksdiyauto]

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]

Yeah, I was second guessing myself for a moment there lol

[@scientist100]

@@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.

never drive with low fuel , fuel lubricates the fuel pump

[@unclemarksdiyauto]

@@ajeys7370 they claim it cools it too. So you always want the pump in fuel.

[@stevenphotog4594]

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.

[@mikehunt2190]

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.

[@Varietystudios897]

Thank you for the video! I have a 2017 tundra and it's doing the same thing.

[@midgetrace]

My bet is the owner run the fuel low very often . With out at least 1/4 tank of fuel the pump over heats .

[@robbocop33r12]

Yep, that's one of the first things i learned on the car tech course i'm on that surprised me. For years the myth was if you run a car low on fuel all the time you're dragging through lots of crap/sediment from the bottom of the tank through the system, but it's the fuel that cools the pump,ad lack of fuel overheats it, something i never knew before. :-)

[@weldingjunkie]

robbocop33 r fuel filter catches the junk on low tanks as well

[@robbocop33r12]

Yes i know, i always wonder why the low fuel/dirt in the tank causing the issue got so widespead

[@weldingjunkie]

robbocop33 r people always throwing myths out because they can’t figured out the correct issue probably lol

[@user-tb7rn1il3q]

Tundras are always low on fuel since they burn it so fast. The pump is a dud. Toyota has a low failure rate on their fuel pumps, but some do fail.

[@stevebrackett2676]

[@andrewvillanueva3722]

Awesome video. I just had my fuel pump replaced in my lexus ls430 2001 after 300,000 miles.

[@KC-xp9of]

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.

[@spelunkerd]

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.

[@ADVANCEDLEVELAUTO]

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!

[@Jake-lr7bv]

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!!!!!!!!!

[@anthonybrooks6907]

probably burned out the pump by letting the fuel get to low ( fuel needed to lubricate the pump)

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.

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.

[@CubasAutomotive]

Wow!! 2018!! Dang! That was a bit unexpected honestly. But it was all confirmed in the end... Excelente video! Un placer ver su proceso diagnóstico! 😊😊👍👍

[@ADVANCEDLEVELAUTO]

[@Nexgeninfi]

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.

[@raullazaro9596]

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

[@ryans413]

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.

[@timmyteabag69]

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

[@mikehunt2190]

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.
