1991 3.0 isn't getting a spark as tested at individual plugs and at the coil.
The wire that carries the pulse signal FROM the distributor to the ignition control module seems to be working just fine -- I get a flashing LED light whenever the vehicle is cranked over.
The wire that carries the pulse signal from the ignition control module TO the coil does not seem to be working -- I don't get a pulse signal from this wire when the vehicle is cranked. Seems like an ignition control module problem.
To make sure that the wire from ignition control module to coil wasn't grounded out somewhere, I put current on one end where it plugs to ICM and a test light on the other where it plugs to coil and it lit up just fine. So that wire seems to be OK.
The individual wire terminals in the clip that goes to the ignition control module all look in great shape. I've taken them out and examined them.
So, pulse signal goes to the ignition control module, but not from the module to the coil. Seems like the ignition control module is messed up, right? But I just replaced it, and I have the same issue!
What could I be overlooking?
