Is there a way to test a PCM?

Im trying to find out if my 94 LT1 PCM is working or not. I have no spark. I put a new Opti on it today and a new coil and still no spark. I have checked all the fuses, so im down to the PCM and ICM. Can I have the PCM checked/tested?

Did it just suddenly stop working? Have you made any other repairs recently?

I'd be willing to check it for you if you want to pay for shipping both ways, but I'd suggest we try to narrow it down, first.

The odds of a PCM just up and quitting for no reason are very very small.

The way to test it would be to put it on another car, or put another PCM on yours.
