No fuel pressure?
89 F150 4x4 5.0
went to start my truck monday and all she did was turn over, my buddy used a stick to do something and said i have no fuel. we looked through out the truck, and manual and couldnt find a solution. (fuses, circuit breakers, ect.) the sending unit on the front tank has been jumpy since i got the truck, but when i switch between tanks they register different fuel levels as they should. and from what it looks like there are 3 different fuel pumps? im am moving across the country in less than 5 weeks and need this truck to run. thank you greatly for you help.

Sounds like the hi pressure pump on the rail, if neither tanks are comming on line. Test pressure at rail. If your showing low pressure & your filter is ok, it would be the high pressure pump.

and to add to what he said....if no pressure at all...then check the relay...
there is a test circuit to jumper to bypass all that for test purposes...
