2000 ram 1500 Has spark but no injector pulse wont start
I have a 2000 ram 1500 with the 5.9. Truck HAS fuel Presure (50 psi) it HAS spark. But it will not start. I checked the injector plugs and they have nothing at all. If you pray ether into the engine IT WILL run. But stop once you stop spraying. I have checked everything i can check. I have even replaced the Crank Sensor and still nothing. I have also swapped out the PCM and still the same problem. I even took the pcm out and stuck it in a durango of the same year and motor and it ran just fine. I cant figure why the injectors have no pulse. What am i missing?
Also The truck has no codes showing and it has a new battery.

If it's firing on starting fluid it's not the sensors. Check that you are getting power12+ to the terminals on the injectors. The ASD relay supplies this but will shut off after a few seconds with the key in the run position but not running. Second get noid lights and hook them up. This will tell you if the injector is getting a signal to fire. If not i would say the issue is in the wiring from the injectors to the pcm.
