Hello, my name is***** fuel pump relay 2 pins should have power while trying to start and 1 should have ground. If all are good that would mean the white/light blue wire that goes from relay to fuel pump is broken somewhere. The white/light blue wire turns into a black/white wire at the fuel pump. If white/blue wire at relay has good voltage while trying to start but not black/white wire at pump then you need to run a new wire between the two. Here is a wire diagram to help with testing. Let me know how it goes or if you run into more questions, thanks.
I've only seen wiring problems once on this vehicle, it is almost always the relay or the pump. There is no fusible link that would effect only fuel pump relay. You will want to check power/grounds at the relay to see if any are missing and go from there. You can continue to reply to this answer at any time without additional fees if you run into more questions so make sure to let me know. thanks.
