I once again will be trying to get both my 1990 ZR cars to start , but I think I need at least one CCM, and my question is:
What years will work on my 1990 cars, and will a regular corvette ccm work ?

You don't need to get into the messy situation of finding and installing a CCM if the engine won't crank. The CCM controls the start relay. The start relay can be removed and bypassed to eliminate the CCM's involvement with activating the starter. The VATS fuel control can be turned off in the ECM chip. Then the engine will crank and fire even if the car doesn't have a CCM.

Good to know!
One or both could solve the riddle.
Thanks Mark!

Thanks to everyone for all the help and advice!

Did you have your bad unit rebuilt or buy a used unit? Did they program everything such as VIN,MILEAGE and Vats and Engine configuration?

I purchased a used unit from Dino's and he has a programmer who is able to put all your info. This was an absolute for me since my car only has 15,000 miles. Did have to match the vats with a resistor. Wasn't cheap but I had tried everything else and nothing solved the problem so it was worth it to me. I did purchase a used CCM before I ordered from Dino and it did work so I decided to use his service and his unit and I will keep mine as a spare although it reads 117,000 miles.

Just thought I would chime in for those experiencing strange starting issues.

Some years back I discovered the clutch-lock-out switch was troublesome by design.

The clutch switch forces the driver to fully depress the clutch to engage the starter. The current travelling thru this switch feeds the starter solenoid directly, so the contacts get pitted over time. This pitting makes things progressively worse. Before long the starter will not engage due to a lack of current thru the switch.

The switch can be by-passed or replaced depending on your preference. The wire to the switch is of a heavy gage.
