EFI HOLLEY HP Conversion with COIL Packs/ Dual Sync Dis, BUt not spark
EFI HOLLEY HP Conversion with COIL Packs and Dual Sync Dist on a 502 MPI. I have no spark. Dual sync is set, fuel pump runs. LS1 coils 558-117 harness. But not spark. I heard some ls coils work different...

Verify you have 12 volts and Ground to the Individual coils , while you are cranking use the instructions to find out the pin number.
When You synched the Dist , I assume you had power to the LEDS?
Make sure your ECM is set up correctly for the Dual Sync , Verify that Relay on the harness for the Coil Packs has power and is actuating when you power on the Key.
Ive seen the relay hooked up with power when the switch is on , but not during cranking , like it was hooked to the ACC side of the switch.
