did some welding now no start condition.

Glad you got it running! I put an orange box in my duster 10+ years ago...went through 3 coils and I doubt I had more than 200 miles on it each time...so I've felt your pain. Definitely get a spare coil! I yanked the electronic out and put my 30 yr old Mallory dual point back in and haven't had an issue on the road since. I have the electronic distributor/orange box still which I might put back in if I get tired of doing points or experience failures from Chinese parts (condenser). I don't know if a poor ground from the ecu will negatively impact coils, but am mopar kept telling me to ground it better as I ate up coils. Maybe the orange box was bad? Would give me trouble when it got hot idling in traffic. If it goes back in I'm going to ground it to the battery and or engine block...not the firewall. Good luck!
