MY ENGINE WILL NOT TURN OVER

2003 Saturn L300 • 120,000 miles

It makes a whining sound. Itested the starter and it is good.

Remove the starter motor and inspect the teeth on the ring gear and the starter drive gear. If they are okay, either the starter drive's over-running clutch is bad or the flex plate is broken around the center where it bolts to the crankshaft.

You can also try turning the engine a little by hand, then try starting it. If that works, suspect worn ring gear teeth.

The starter and fly wheel are good. Could it possibly be a bad alternator?

The generator has nothing to do with starting the engine unless the battery is discharged.
