No power to fuel pump 2004 RAM 1500 5.7
List of what I have done so far: Used a jumper from battery to pump and verified pump runs... Checked and verified relays & fuses were good... Confirmed a ground... Performed continuity test on power wire to the fuel pump from fuse block all good... Replaced crankshaft sensor... I am now at a loss???

There's nothing left except for FUSE 17 feed. Put your test light on 17. If it's dead then your IPM is shot. You can wire in an external relay circuit if that is the case. I've done them several times that way. If the relay is clicking then you obviously have PTC power and PCM control ground. If the fuel pump works when jumped, then the wiring from the IPM out is fine.
