I have a 1990 Lumina w/V6. Engine turns over but won't fire. Could it be the Ignition Module?

With engine cranking, do you have spark at the spark plugs? With no spark, suspect the crank sensor first. Also check for voltage and ground at the ignition module.
If you have spark and injector pulse, I don't think it is the ignition module.
