ECU Failures

[YoungGun74]

Just looking for a little help here. I have a factory electronic ignition system on my 74 Dart Sport. It has an OEM 4 prong ballast resistor and an MSD Blaster 2 coil. I had an Orange Box go bad but figured it was just crappy quality and it was about 3 years old. I replaced it with a new Jegs brand ECU and after 3 weeks that one has now stopped working. Not sure what could be causing these issues and looking for some guidance on what to check.

Thanks

make sure its getting a good clean ground. bought a Volare back in the day on the cheap because it didn't run. cleaned up the ground for the ecu and drove it home.

This is one of the many reasons I stopped running the mopar boxes. Honestly, do away with the ballast and get an HEI distributor OR and MSD (or similar)

Took your advice and got a Ready to Run system from Blueprint

YoungGun74 inbox is full. Just wanted to follow up and see how the blueprint ready to run worked out for you? Was thinking of picking one up myself along with the coil they offer. Thanks.
