Update,

I was researching the forums for ideas on the no crank issue and my wife interrupted me as the car alarm was going off in the driveway. Key FOB worked to disarm it. Had power again. Dash lights and all power items worked. Turned the key and all went dead again. I suspect the RCM is the issue.

Any thoughts on getting another one? I’m pressed for time to get this one checked as my son starts school next week.
