Fuel pumps shutting off, losing fuel pressure on highway
Well, I just started a new thread. This is what i have replaced so far.
Fuel pressure regulator
cleaned IAC valve
Replaced tank selector switch
Cleaned intake manifold, replaced gaskets
These are my problems.
My truck has two fuel pumps, the symptoms happen on both tanks. My truck will run fine all day, run for hours. it seems like it only happens when my truck is warm. I will be driving on the highway and ill feel my truck jerk, the CEL will emit, but i still have power steering and braking, i floor it, and the light goes off, and jumps back into gear, this happened twice on the highway yesterday.
The truck will be running at a stoplight, and be fine, no bogging, and out of nowhere just shut off. The truck will not start up again. I have learned to not try and crank the engine at all, and let it sit with the key in the "on position" and if its quiet enough, after about 10 or 15 minutes the fuel pumps turn on, and it starts fine.
And here is my other problem, i can drive it all day, or up the street for 10 minutes, and when i shut off my truck and come back out to start it the engine cranks but no fire, and i let it sit again with the key "on" and the relays click over and it can start.
Yesterday the highway problems happened after my truck shut off at a stop 20 minutes prior. I washed my truck through an automatic wash and the engine light came on, and has been on for a day, sounded like water in the exhaust, but when my truck shut off the CEL was on, and after waiting for the 15 minutes for the relays to come on, the truck started and the engine light was off and has not come back on, I don't know if its a coincidence, or my computer resets after the truck fails, as stated before, this isnt my first thread on the same problem, but here is the list of what i have replaced and tried, Thanks Ford Forums, you guys are awsome.
