Default 2001 Buick Park Avenue, No Spark, Random Spark

Helping a friend with his car, it stalled on him and he towed it to my place.
The codes said bad CPS. We replaced that. After that we had spark from the first coil, and that was it. I ran through the CPS/ICM testing procedures on here and everything checked out, so we replaced the ICM. At first we had spark at the first coil and the 3rd, but that was it. We decided to check the wires and pulled the CPS and ICM and replaced.

This is where is gets odd, when we connected everything and hooked the battery back up, the thing tried to start on it'* own. The owner did have a remote car starter installed awhile ago.

I ran through the ICM tests, and the only odd one I see is that the the G wire (18x) wasn't reading 6 volts, if it changed at all it was 1 volt or 2.

This morning when checking for spark, we have none again.

I am not sure what else to try. I did verify all of the grounds and clean them. I ran the codes again and only have one for MAP. I occasionally get RPMs on my scan tool when turning it over.

Do a drag test on the female connectors at the ICM harness?

If you have spark, on even just one cylinder, the crank sensor is ok.....

You replaced the ICM? New?

If you are getting no spark from a coil, did you try swapping with a coil that sparked? Did you pull the coil and check the primary circuit out of the ICM with a test light?
