No Spark Question

Friend mine came over to see if he could figure it out. He went throughout everything. He even questioned the ground. He found nothing wrong anywhere, that's why he decside what the hell and we plugged in a spare orange box ground with a jumper wire. The car fire right up, crazy. I work at Oreillys and got the best I could get for an ECU. I going to start planning a swap to the HEI. This is the first time in the five years I have had the Mopar ignition give me fits. No more ECUs for me.
