If the fuse is good, move on to the relay; since testing the relay manually is annoying, replace fuel pump relay with known good relay and attempt to crank.

If you still dont get the fuel pump on, find a way to run 12v+ to the fuel pump to ensure that the pump does in fact work.
If it does (which it should if its new), then your issue lies in the power delivery to the pump. If you put 12v+ to the fuel pump and it still doesn't kick over, you likely have an open ground.


I'm ignoring the ECU aspect at the moment only because if the ECU was dead, the truck likely wouldn't even crank.
Fuses are all good and I cant find the relay! Everything I find says it doesn't have one it has a fuel control module
