Most of the time it will be a bad starter motor, but once the starter motor is out use a flashlight to check the teeth of the flex plate. Here is a guide to help you step by step with instructions for your car in the images below.

You will need to remove the air box and throttle body. Check out the images (below). Please upload an image or a short video in your response, so I can see what's going on.
