) which looks like my exact distributor. I show no spark at the plugs, and no spark at the coil, but then when I test the ignitor (ICM) I get an unexpected result.
Rather than seeing a ground with the key at ON, that will either flicker at crank (ie, good ignitor, bad coil) or go completely out (bad ignitor), I have no ground whatsoever. I do have a good ground on the distributor body, and I have done the 'Ignition Control Module (ICM) Input Test' from page 4-19 of the service manual. This involves unplugging the ICM and making sure all the wires have proper continuity and voltage, even testing the wire from the ICM to the ECM/PCM connector.
These point to the ICM being bad, but my impression is that the test assumes a working computer. So here's my question. In that video, Eric identifies failure in the ICM by seeing the test light go out completely.
My test light doesn't even come on in the first place. Is that also indicative of a bad ICM, or does that mean I have a problem even earlier than that? If I do have a problem earlier than that, my hunch is that it's the computer (ECM/PCM or ECU). I pulled that out and opened up the case, and I don't see any obvious damage or burnt spots.

I have not yet done the complete diagnostics for the computer, because I think that my lack of ground at the coil might be definitive. Any opinions? Please or to join the conversation.
