My guess is either:
* you don't have switched +12V on all the pins, and the stock ECU is robust enough to work without it but the PFC is not.
* your ECU relay is not wired correctly (needs to be wired to the ECU so it "turns itself" on with ignition power, rather than turned on directly by ignition power). Usually this is a problem programming PFC's, not starting them, but could still apply.

so now im leaning towards doing this to see if I can get spark all I need is a 12v source and a wire to this 12v plug in to see if it gets spark and see if it fixes my problem how would you guys tackle such a job
