Intermittent No start.

I love the petronix I, I just had my first fail in my car, but could have been me leaving the key on for other work (troubleshooting) Mallory mech YL. Not a big fan of the III, have seen three failures on them so far so I wont go near them. As for factory mopar ecu it is a great system the trick is to find parts made pre 1980 for them. I have been picking up NORS ECU's lately for all in one kits and have a old Tektronix tester for them like they used to have in the parts store. Standard and Neighoff seem to be the best for Mopar. Really like the Kem GM 4 pins. The new stuff has a serious high fail rate around 50% when hot. Same on pick up coils and also points condensers.
