I have a 1987 S-10 Pickup 4x4 with a 2.8 V6. The truck will not start or even fire. I get no spark at the wires when I try to arc test, I tested the coil and it is fine. I know the distributor is fine, so I am stumped. I was told there is way to test the Electronic Spark Control module, but I cannot find any information on this, but at the same time I was told that these modules very rarely fail. I would appreciate any input that you might be able to give.
