Since the install it has about 10 min run time give or take. It has a stock electronic distributor, coil & an orange ecu box. I have checked the wiring just to double check myself. I take #1 plug wire off the plug put a screw driver in it and hold it about 3/16 away from the shock nut. It seems to have good spark. Where the ecu is bolted to the inner fender i scraped & sanded it to bare metal. Ill check that again. Its all new. Its gotta be some thing im over looking. I suck at wiring & taking pictures lol
