position, I do not here the fuel pump turn on when I go to turn on the truck. the
adapter they gave me for the fuel pump is faulty. The plug in from the truck

A fault in a wire or fuse? Were you in an accident, or a sudden hard stop. Could be the inertia switch has shut the pump off. Your owners manual shows you the procedure for turning the fuel pump back on. Manuals also available on-line.

No I havn't been in an accident. It was working just fine for a few months then randomly it stopped working


All wiring is through the plug, so I don't see a ground issue. I believe the fuse for the pump is next to the relay; ECMb, a 20 amp fuse. double check this fuse.
