1984 Ram Crank No Start
Or you can run a separate ground wire also.
I've done that on every car I've owned, this truck is new to me a few months ago.
I'm doing some of the wiring over, installed both a ground and positive hub today, as well as a bigger ground cable, separate ground wires for ECU, starter relay, a ground wire all the way to the rear taillights, the headlights, etc.
This all began because I was going to install trailer breaks/light harness, which I did most of it today.
Picked up a new ECU as well.
Going to finish up the re-wire/trailer wiring I had planned anyway, then try to start, then replace the ECU, then with any luck this will be over.
Still do not understand what steps I took diagnosed/ruled out what issue/part.
