I have 1988 F250! Does anyone have any info? Truck ran fine when I pulled in the garage. All I done was hook up the entire plow setup. I tried to put a new fuel pump in and nuthin. aaaaaaaaahhhhhhhhhhhhhh! There is no noise when you turn the key. (Coming from the tank) ya know that humm you usually hear when the pump kicks in, a buddy said it could be the front/rear fuel tank switch but I dont know much about those switches. Any info or suggestions will be helpful. Thanks

 

If its a new pump, but there is still no humm, then it is probably your fuel pump relay.

 

check fuses to see if any are blown or relays loose wires. Does it crank at all?

 

Yea it cranks it just wnt start. Acts likeits gettin no gas. ??????

 

The relay is clicking. Is is suposed to?

 

what do you mean ? clicking fast or only when you turn the key on.

 

when you turn the key on

 

do you know where i can find a fusebox diagram i can print out?

 

thats good then you say you dont hear the pump turn on. Have you checked spark?

 

youmean plugs? Yea its gettin fire

 

no pump though

 

When the truck is turnn over, give her a shot of startin fluid and see if she'll fire

 

tried that it barely spit a start after a couple squirts but it died instantly

 

no, no pump

 

will the switch from front to rear get stuck to where neither one will allow fuel? thats what a friend suggested but i dont know anything about those switches
