If no volts at coil plug I am going with PCM is Bad???
Trying to find some more ideas, I'm about to give up and tow it to a shop. 2003 dodge durango 5.9L. D was running fine, walk out one day to leave and it will not start. Engine spins but will not crank. Fuel pump is on and can smell gas in the exhaust while trying to start. There is no voltage at the coil. Replaced coil, crankshaft, coil pick-up and battery even though they tested good. No codes on a scanner and no codes on the odometer. Did continuity check of the coil connector wire back to the ecm. ASD relay is good. All sensors have 5v. Are there any other non related sensors that would cause the ecm to shut down just the ignition? I've read alot of post but every one was able to fix theirs with the things I've tried. Hoping someone else has had this problem.
Thinking that might be right. Guess there is no test for that without just swapping another one. no mechanics around here will touch dodge ignition problems. only one shop with the equipment and then its dealer.
did the onboard check and odometer reads 'p-done' no codes. do you know if any transmission sensors can cause this?? and i cant remember if the oil gauge will show pressure while cranking or if it resets the panel when the engine starts and then shows pressure. there is no oil pressure while cranking the engine but i replaced that sender and do have oil pumping out without the sender installed but i don't have a pressure test gauge to put on it. I don't think the pcm monitors oil pressure or does it?
If my memory serves me correctly the ASD relay controls the voltage to the coil and it only has voltage while the engine is cranking or running. You won't have any voltage with the key on not cranking. The PCM controls the ground to the coil.
I will double check for voltage while cranking. I did swapped relays with the rad fan and the fuel pump does start when the key is turned.

My first guess was coil.
My second guess was incorrectly installed replacement coil.
My third guess was NO BUS but P DONE eliminates that one.
Alarm anti theft issue is engaged **if** all else checks as good.
Use key to open/unlock D **in** the drivers door lock (yea, old school "unlock" the drivers door), or use the FOB remote AND use the key in drivers door, or remove all related alarm/anti-theft fuses and try again.
