Okay, I'm no noob to this stuff, I been working on these trucks and all ford late model stuff for years, but this has got me baffled.
I bought a wrecked L, not a big deal, I have fixed tons of wrecks.
When you start the truck it idles up for a split second then dies.
Sometimes it catches itself and idles up again or idles rough for a few seconds then dies.
If you put your foot on the throttle when you start it, it will start up and rev then will die immediately.
I thought that there may be a connection issue with a fuel pump but that looks good, checked the IAC also good, changed both fuel pump relays, and looked over every bit of wiring that I can.
There are no codes in the truck except for the seat belts and the passenger air bag because I haven't replaced them yet.
So, I'm down to thinking that the fuel filter may be clogged or :shrug:
Let me know what you think, I'm about stumped!
