Thanks everyone for the information im going to send my ecm to get fixed but why cant I just supply fuel to this sucker add pressure and be running somehow i am kinda bummed that the computerized stuff is so fragile

I wired this precision inline replacement to the original pumps wires, its not getting power so I ran my own power from toggle switch and it runs holds good 25psi hardly have any fuel coming back on the return,wait to start is coming on and looks normal but tbe truck will not start or run after started with help from fluids im stumped changed cam positioning sensor and pump and relays and was wondering about throttle positioning sensor should I change it but i would like to know what the resistance should be at the pins so i can check it before spending 230.00 which is what I am getting quoted from autoparts

I have a 2001 Ram 2500 Cummins 4 by 4 automatic and I cannot get my fuel pump to a cycle on relays good fuel pump is new I can run a hot wire to it and it runs but the truck will not start is there a fuel pump shut off switch somewhere I still annoyed or something that I should check and where would it be located
