it ran until the obd-1 ecu was put in (with conversion harness), obd-1 dizzy of course wired for the obd-0 harness and i confirmed with chaarles it was right. the car just turns over. it wont start. we have spark, fuel pump primes and you can slemm it and of course there is air. i am wondering since the map sensor was relocated onto the obd-1 TB if the wires need to be swapped. i know on EF's it has to be done but i cannot find squat on an LS. i'm baffled. i can try my b16 ignitor to see if the one we have is weak but it's strong enough where i shocked myself on all four plugs by accident(hand on dizzy).
