and whatever else it req's will get done once I get it to lite of. Any chance the
crankshaft sensor is causing this ? I'll try and get a screen shot of my old
scan tool when cranking the engine and post it up.
Thanks again.

As I explained earlier if you are getting a cranking RPM reading from the scanner then your crank sensor is working and being powered through the ICM, and so your ICM is getting power also. This is why I said if you don't have spark on two or more coils then the ICM is indicating bad regardless.
Have you checked for spark on 2 and 4 or 4 and 6 yet? Most of the auto parts stores around me test ICMs, you probably have different stores where you are. The ICM doesn't even need to be tested off the car really. If you have crank signal which you're saying you have and if you don't have spark form any coils, then the ICM has tested bad by the process of elimination.
