So my truck would randomly shut off while driving and say check gauges, with an engine light saying fuel rail pressure sensor, I replaced the sensor nothing happened, turned out it was the pigtails to the fuel pump driver module, after dumping over a thousand dollars in this truck and getting the pigtails changed 3 times, It still does it. Usually after 30 minutes after run time when the truck is warm. Then after shutting it down and restarting it 3 times after letting it cool it drives for a little bit. Im having so much trouble the mechanics don't even know whats going on. Someone please help me this is absolutely a nightmare

 

Is it a 1977? 1988? 1999? A little detail goes a long way as we have no clue what truck you have.

 

It is a 2005 f150 super crew cab fx4

 

Have you checked the fuel pump driver module on the rear frame rail ? Meaning remove it and look at the back side of it. They tend to corrode and fail. I know when I had my 05 it was all corroded

 

need to do some testwork to start narrowing down possibilities.

get it into a failure state. be ready tomremove
intake tubing, spray starting fluid directly into the TB. try to restart. does it pop/fire?

report back with findings

 

Its brand new doorman, second one after the other one broke, just bought it a couple months ago

 

I did this already, The truck starts running normally after cooling off for a little bit, it happens when driving for like 20-30 minutes

 

you did that test already? well, what we’re the results ?

 

so it runs perfect, I timed it and it exactly dies 30 minutes after it turns on when I’m driving, idle time included. I stop and start it 3 times and it runs a little longer before giving out.

 

that doesn’t describe doing the test. good luck with it.
