My 1988 F150 2wd, at, ac, ext cab, 5. OL EFI was occassionally not starting, cranking but no fire. Took to shop n they said could not duplicate and banged on bottom of tank and checked other things and I picked it up and paid $100 bucks for nothing. It's been running for about a week, had to bang on tank one other time but then last night got stuck at store. Turned key on and off 7 or 8 times then banged tank and all of the sudden it started after sitting about an hour. Then all today, nothing? The pump primes or I hear it buzz for a few seconds, there is pressure at that bicycle valve on the fuel injection bar when I press the valve stem down.I see the fuel relay switch on left fender next to the airbox under a rectangle cover. Could it be that switch? Do they go out ever and would that be an inexpensive minor mechanical way to start for someone like me who is not a greta mech. Or am I just looking at the replacement of a pump/sending unit? Oh, and the truck has two tanks but the sending unit on back tank has not worked for two years since I bought truck so I always run off front tank; have not touched that switch. I'm a single father working a temp job 25 miles away and have $200 to my name. If I can't fix this myself I'm. Well out of work and soon homeless as I just paid March rent and live week to week with Kids on my temp job. Thank you for your help; ). Desperate dad!
