No Spark Question

OK, but now you are going to get some people here (not me) riled up because they swear the Mopar ECU is extremely reliable and the only thing people should be using, no GM inter-breeding. Others have taken some of the new ECU's apart and found fake TO3 transistor cans with a wimpy little transistor tacked to the top case. Might work OK, but looks suspect. Anyway, glad you found the root cause. That helps many here.
