Electrical problem
1997 Dodge Ram V8 Four Wheel Drive Automatic 300000 miles

I have a 97 dodge ram 5.9 L with auto trans. I have a new ECM and have run a wire to test the fuel pump cutting on and that works when I ran the jumper. I turn on the switch and all the nor. Lights come on but not the engine light. I try to start the truck and I get on spark and no fuel pump running does anyone know what the problem is.

Test the ASD relay or swap it and see what happens-This relay powers the coil, injector and fuel pump relay then to the fuel pump.

I have checked and swapped the relay out with 2 others that work and still nothing it is like the computer is not responding but I know it works because I have a 96 dodge ram and it starts it right up. The truck ran fine and I was about to have it taken down to the trans shop for some work on the trans I went out to test the trans out it wouldnt start. The old computer that was in it stopped working and I pulled the one out of the 96 and put it in there and left it at the trans shop and they tried to work on it and got it back in the same shape as I dropped it off just with the 96s computer not working either. So I will only hook up the new computer for a test on the start when I get a idea of what it might be. I am getting 12V to the red and white wire on the computer and a ground on the black and white wire so I am lost

I guess you didnt read I have checked all fuses and switched out the relays. I have always fixed my own cars and trucks so I know how to check all the simple stuff and I have done all of it even as far as changing out the O2 sensors and the map, crank, and cam sensors. Has new wiring harness but still nothing
