kay Im running an obd2 ecu and used and obd1 with distributor harness and the car wont turn over. Is there any difference in the wiring when using an obd2 ecu and an obd1 distributor to make it not turn over. Because I tried 2 different dizzy and finaly got tired of it and finaly opened up the two dizzies and swapped the insides and used an obd2 and it turned over so . . . is there a difference in the wiring for the ecu to make it not turn over.

 

so what anybody . . . nobody? Or ca it be the distributor conversion harness

 

What engine? D, B or H

I have no idea, I leave that to the experts. But I'm sure more info is a good thing.

 

Oh shoot my bad its a b20 in an ej
