Only 9v to coil, no spark HELP
So Iíve been trying to get my 1988 535is M/T going and have had nothing but issues because of the PO repairs.. I have recently replaced the fuel pump and filter, all the relays and fuses checked all my grounds in the engine bay but all the car does is crank. I tested the ignition coils ohm values and they checked out as good. With the ignition on I get 9.2v at the coil and when I crank it doesnít produce a spark.. I know the ignition signal is sent through the ECU pin#1, is it possibly not sending the ground to spark? I am out of ideas. I also swapped another ECU in and it made no difference.
