Look into swapping in an HEI dist.... It will replace and simplify the entire ignition system.mrnascar30 said:Hello all,
I have a 1990 Jeep Wrangler 4.2 6 cylinder. I have changed out the ICM (Ignition Control Module) two times and it failed again. I know this is the weak link in the ignition system, but this is ridiculous. My question is this. If I use an MSD ignition box, coil, and distributor, can I eliminate the ICM?
