most likely your bendex wheel in the starter is not engaging the flywheel this could be due to a bad solenoid on the starter. chances are it's a bad starter, i would check to make sure all connections to starter are tight and you have atleast 11.5 -12.5 volts of current in the battery. low voltage can cause this problem as well

hello first thing you need to do is take your starter out the starter drive gear either has busted teeth or the flywheel does with the starter removed mark the flywheel with chalk crayon so you no were you started from look at the teeth good keep turning the motor by hand checking till you come back to the original mark you made if there are no chips or missing teeth look at the look at the starter drive teeth there most likely busted or chewed down replace the starter goodluck please rate

The flywheel is worn in that specific area. Engines tend to stop in the same one or two positions, and it is those teeth that get cachunked every time you turn the key. This is ok if the bendix does a good job of threading the gear into the flywheel teeth, but the problem is that now that the teeth are half worn away, the starter attempts to mount its gear to the teeth, but before the gear is fully seated, the contacts in the motor make, the motor starts to turn, and the not-yet-seated gear bounces off of the flywheel teeth. This is what causes the teeth-grinding sound (your teeth grinding in your mouth too!) when you turn the key. . There are two solutions: The first is to, of course, replace the ring gear. . The second is hard to explain, but a good starter rebuild center (if there is such an accessible animal around anymore) will know what I'm talking about: The starter gear must have the lagging edge of each tooth ground so that each tooth will look like a chisel. The "pushing" side of each tooth must be straight and come to the point (and not be beveled). The "non-pushing" lagging side of each starter tooth should have the bevel ground in on that side. This grinding is done easily by a small angle grinder or a Dremel Tool with a cutoff wheel. . This does one thing: It assures that the gear will "spin in" without bouncing. If ground correctly (it's not hard to do), you will get successful starts every time. This is a common fix for Toyota 4-cyl with this horrible all-too-common problem. Good luck.

It sounds like the starter is not engaging fully and you should change the starter.When you remove the starter check the flywheel\flex plate(Flexplate for automatic trany) for damage.
