Have you checked the fuses? If you have a meter you can check for power at the fuel tank connection and if you have none work your way back from there to see where you lose it.

What engine do you have? What year truck? What model? That will determine what style fuel pump or pumps you have and how they are hooked up, unless you have added something aftermarket. Then we can help you figure out what possibly can be wrong.

Wrong year forum. You have electric in tank high pressure pumps or pump. That's a lot different from most of these trucks, which have mechanical pumps or low pressure electric pumps in the tanks.

Ck fuel press at rail .Have you cked for codes ? you need to ck fuel press first . Then go from there . If no pressure ck for power and ground to pump. If pressure at rail look for other cause for no start .

Ck fuses , Inerta switch , Relay . try switching fuel pump relay with another relay . A wiring diag would be good to help you trace it down . could be in the harness even . You said no power , how did you test ? Good ground to pump ? Just asking .
