Thank you for the replies: I truly appreciate the feedback. I have a few questions that I hope you can help me with. Where is the crank sensor? Is there a way to determine which is at fault (RCM vs Crank)? I've taken a quick peek at the jumble of wires in that box to the right of the battery. How do I know which is the RCM?

Also, in regard to Tulsa, I'm suspicious that it could be the sensor that tells the car that it is in park because the first time she wouldn't start, I put the key to "ON" and moved the shifter to neutral and then she started right up. Now, however, I cannot move the shifter from park at all, no matter what I do. On the other hand, I specifically checked the indicator on the dash before shutting down and it said park. O' car electronics!

Thanks again. This is a very helpful discussion forum.
