Hi, I'm still battling this issue and thought I would ask the Moparts gang for any thoughts. Here is the deal.
When my Challenger is cold it always starts.
When it gets warm and I shut it off and it sits for a while it won't start.
The car turns over but it is not getting any spark when the engine is turning over.
If I just leave the key forward (not under load) and jump it with a screwdriver on the start relay it starts.
So the "no spark" issue is only under load (key all the way forward, engine turning).
I had upgraded to Electronic ignition. I have a new ECM, ballast resistor, starter relay, plug wires, cap, and engine compartment wiring harness. I even replaced the bulkhead with all new connectors. The positive side of the coil shows it is getting power.
I'm thinking of replacing the distributor next.
Thanks for any suggestions.
