Hi,
I have a couple of questions. First, do you have a live data scan tool? If you do, see if there is an RPM signal when cranking the engine. If you don't have one, check to see if the tachometer moves a little when cranking the engine.
Next, at the ignition control module, locate the pink wire. With the key in the run position, check that wire for power. If there is power, check the black wire for continuity to ground.

Try this and let me know the results.
Take care,
joe
