Could just be flooded.

To see if it's blown, see http://www.aaroncake.net/rx-7/blown.htm

Could be the starter motor spinning but not turning the flywheel or broken teeth on the flywheel. Can you actually tell if the motor is turning?

If your engine sounds like the vid Hit Redline posted, then the solenoid isn't engaging the starter drive to the flywheel. Before you pull the starter for testing, run the ghetto compression test Aaron describes. In my sig line is a link to the online FSMs. Download and start reading, good luck.
