No spark
Run down:
63 Chevy Pick up
Freshly built motor
1999-02 PCM / Harness
I know it's not an issue of the PCM not having power as it fires the fuel pump up, turns it off after 5 seconds like it should. However I get no spark. It also uploads/downloads a tune. Plenty of fuel pressure on my guage.
I'm going to double check the power to the coils, but any other suggestions?
is a crank relearn in order to fire a fresh build?
Vats is gone but I think it would still start if there from what I under stand, just wouldn't run for long.
TIA..
