1988 Ford F150 V8 Four Wheel Drive Manual
My fuel pumps will not actuate, the fuel shut off switch is fine, both relays replaced, ignition switch replaced, all three fuel pumps replaced, computer has been replaced, and I have checked every fuse, wire, and conection I can find. I don't know if injectors are working, however, pumps work if relay is jumped with "hot" wire. Will start and run if primed but fuel system doesn't work. I tried the shotgun effect and came up with a total miss. It did this a year ago and the next day it worked fine with no repair, this time it died. Any ideas? How does this system work?
have the same problem?
