Here's the final verdict:

The Relay Control Module WAS indeed the problem. Two weeks now, without a single no-start problem on the '05 Crossfire. This confirms in my mind that sure enough, it was the culprit.

The local dealer has not called me back about releasing the old part. If they do, I'll troubleshoot it and post pictures. If not, I'm signing out with my sincere gratitude and THANKS to everyone on this board who goes to the trouble to post in-depth solutions and offers their help. It's been enormously helpful on this end, and I'm very grateful! (So's the wife!)


Thanks!

Brian
