I'm spent... need some ignition advise.

I had the same problem with a 87 dodge ram. I took the electronic ignition harness from a kit I had and wired it in and eliminated the factory hook up. It corrected the problem. It even started better hot. It was a blower motor and it drove me nuts for awhile until I did this. Later when the funds permitted I installed a MSD 6-AL. There was something in that truck that interfered with the orange 4 wire control box. Steve
