It sounds like you may have an electrical wiring problem. Typically, you should have 4 wires (2 with ground, one with power and one with switched power) that are working to complete the circuit. The ECM will connect one of the ground wires to complete the circuit activating the fuel pump. These types of electrical issues can be very difficult and time consuming to trace. I would suggest having a professional from YourMechanic come to your location to diagnose and inspect the truck.
