I have proved to myself I am not getting voltage to my lift pump (in the tank), can this only be the Engine Control Module or is there a combination of inputs the ECM needs to tell the pump to pump? All the relays and fuses seem to be good. I will probably add a relay off a (start and run) fuse in the junction box before I replace the ECM on the side of the engine. $$$$ This truck is only showing 324K miles. NP4500.
