Ok I have one ecu (chipped p06) that has spark and primes the pump but no injector pulse. One side of the injector has 12 volts the other side ohms out 0 to the ecu. It is not firing my noid light. The car is obd0 and the ecu is obd1. I am running a obd1 dizzy, a dizzy conversion harness and a obdo to obd1 conversion harness, For the injectors I am running 240 cc 3 ohms with a resistor box.

Did I do It all rite? Is there a problem with the 240 obdo injectors and a box?

I think I have bad injector drivers. If I do I have a bad obd2 ecu (I cut it up to make a obd2 to obd1 conversion harness but it was working)

So the injector drivers are part # On the obd1 ecu are
SK 103
STA460c

And the injector drivers are part # on the obd2 ecu are
SK 542
STA460c

Dose the 103/542 make a diff? Can I just swap them over?
