273 Electronic Ignition Issues

UPDATE: I know it's been a long, long time. Anyways, I'm back at it and after purchasing an OEM ECU (ICU), and hooking it back up, the old Dart fires right up without issue. I believe the aftermarket junk ICU was a problem, but not THE problem that caused it to shut off when I hit the pothole. I think a wire came loose on the ballast resistor. When I was tracing the wires earlier on, I notice the bottom wire on the resistor had fallen off. So I tightened that connection and installed the new ICU from halifaxhops. Zero issue now. Thank you all for your replies and assistance! Happy the old girl is running again.
