my rx will not start and the motor sounds like it is not turning. It started one day, then the next day nothing. The starter is find and the battery is charged. I'm almost wondering if the flywheel is not griping my starter.

Does it make any sound or crank over at all? Give me more details of what is happening and whats not to better help you. If your flywheel isn't gripping tighten your starter bolts. That happened to me when someone else worked on my car one time.
