Hey Scotty, I love your content and visit your channel regularly. Shoutout from Pennsylvania. I just bought a very clean 2012 Toyota Tundra 4x4, SR5 crewmax with the 5.7 I force V8. 153,000 miles, auto trans. I was driving home from work yesterday when about 40 minutes into my ride my truck shut off and now it only starts for a few seconds and immediately stalls when I touch the accelerator. It starts right up, then slowly bogs down and stalls after about 20 seconds. It is throwing a A/T to temp light (gauge reads normal right in the middle), and a check engine light. I also noticed the 4hi and 4lo light flashing And the ‘traction control off’ light came on a few of the times I started it. It is in 2 wheel drive. I have not scanned it yet, but It behaves like it’s starving for fuel. This is my first Toyota and I’ve heard when something goes wrong they like to throw all kinds of dash lights. So far I’ve tried cleaning the MAF, unhooked and cleaned up my battery terminals and connectors to make sure I was getting good voltage and ground, let everything reset and had no luck. Battery is only 2 years old and an OEM Toyota part. Will be listening to see if the fuel pump kicks on next but I have a feeling it’s not the pump because it starts right up, but more likely a clogged fuel filter. Have you seen anything like this before or is there anything I’m overlooking in my diagnosis? I appreciate any feedback as I’m new to the Toyota world. Thank you!
Where you at James the fuel filter definitely a clogged fuel filter can do that but rather than gas first look for a vacuum lines it may have fallen off if there are any of them fell off do my video fixing the car that cranks but doesn't start up. And yeah it could be the fuel pump they can pump but not pump enough pressure so they start and then die I'll so check all the wiring around the battery any corrosion will lose power to Old wire
Thank you. I will check for vacuum leaks next. I can hear the fuel pump running, but I can’t tell if it’s running the right pressure because I can’t find a location to hook my fuel pressure tester up to. I will have a scan tool to use later today to see if that helps any. Will update as I rule things out.
UPDATE: upon further investigation, I can not hear the fuel pump kick on when turning the key to ‘on’. Also it has trouble codes P0102(mass air flow circuit low) and P0113(intake air temperature sensor system open/high). Replaced MAF sensor, didn’t help.
