Truck will not start after replacing old fuel pump.

Went 4 wheeling the other day...parked the truck and turned it off. Several minutes later, it would not restart. Could not hear the fuel pump engagement sound, therefore i figured it was the fuel pump. Purchased a new one, and reinstalled the new pump.

You can hear the electrical engagement for 1-2 seconds, but it would just shut off and the truck will not start. I have a feeling it is an electrical problem.

checked fuses, battery, ingnition, installation of new fuel pump, and wiring. all are fine, but the truck will not start.

Is there a restart or reset button somewhere that I am not aware of?
