i have an 89 f250. having issues with the fuel pump system. my truck died the other day, the fuel pump wasn't kicking on. i tried replacing the relay, nothing. pulled the pump and tested it, it works just fine. i tried running a new wire from the relay hot wire to the pump and that got the truck running, but the fuel pump won't kick off ever. help

 

Moved to correct forum.

 

Check the fuel pump cut-off(accident(inertia) switch) that's under the driver's side dash area on the firewall. Reset it by pressing down the red button. If that still doesn't help, use a test light and see if you are getting power to that switch. If you have power to it but none out, its time to replace it. My failed and I just capped the wires together while on the side of the road.

 

If pushing the button down on the fuel pump cut-off(accident(inertia) switch) or jumping it does not help then:

Does the fuel pump relay click when you turn on the key and click again (drop out) one second later?
If not ground pin #6 of the Self-Test plug on the drivers fender and turn on the key and see if the selected fuel pump runs then.
