Actually I screwed that up. With a ballasted system, you do NOT want to interconnect the two. Crackedback is right you need to see if you are getting that voltage from IGN2. Wiring diagram? MyMopar. See if coil+ has voltage during cranking, it likely not
Coil and ECU need power during start. I suppose if one is hot the other is also but... just never know. Dual ballast was deleted so maybe a current path to ECU was lost?
