No Start issue - UPDATE kinda long

Most of the problems with the control units were with the grounds. A couple of old Mopar tech's from the 70's told me along time ago that the boxes need to have a seperate ground to the engine and not to rely on the fender/firewall for grounding, and make sure that the box and the block is very clean where the ground is going to be. This is a inherent problem with the Mopar or aftermarket units.
