Electrical problem
1985 Chevy Blazer V8 Four Wheel Drive Automatic
I have no spark at the plugs. I've tested the coil and it's good. I've changed all the electronics in the distributor. There's a new cap and rotor plus plug wires and plugs. I've got 11.97 volts at the distributor with key in run and start positions. My wiring diagram shows an ECM with about 20 wires going to it. However, my ECM only has about 9 wires. I'm at a loss for what could be wrong.
