02 24v no start

Cold be in wireing like mentioned before, may want to go through all grounds and connectors, make sure nothing there. All the ground wires in harness use some sort of glue/press/crimp connection, it's a good idea to unwrap wireing loom and redo all grounds. Could be just a lise connection some place, wireing gremlins are the worst.

I think if both the ECM & PCM came off a the same working truck and dont work on yours that it would have to be a wiring issue, grounds, or god knows what. There is a lot to match to know for sure.

What is that red wire that has a messy connection to the alternator output terminal?  If there are more wiring connections on your truck that are done in that manner, I would be thoroughly looking over the electrical system.

@Mopar1973Man, in the last few days I have noticed that there are no longer any names associated with "Likes" for my posts and others that I see.  For example, I have two "Likes" in my previous post, but I don't know who they are.

 

Anyone else experiencing this problem?

Mine still shows who.

And Fix that connection as soon as possible.  Something is probably loose there.

Just wait till the alternator fuse blows and whatever that is that red wire powering will most likely burst into flames when the charge voltage goes over 20 volts.  This is something I wish AirDog would take out of there install manual. Anything hooked to the alternator line will instantly burn up when the fuse blows this includes electronic devices or electric motors. 

Why? Because the PCM will no longer see the charge voltage and will crank up the field to max power so the alternator no longer connected it will fry anything hooked to it. 

NEVER hook anything to the alternator line between the fuse and the alternator you asking for vehicle fire for sure.

If the ECM is bad, try one from another truck. I had to do this to get my truck home. I used one from a 2001, and only thing the didn't work was the oil pressure gauge (different signal/wiring).
