If the starter is spinning without cranking the engine, there are two possible causes, but both are related to the starter. The drive gear's over-running clutch could be broken or worn. They can be intermitent or they can fail completely.
It is also possible for the drive's shaft to become rusted so the gear won't slide freely to engage the flywheel.
If you have the little silver Nippendenso starter, they also develop worn solenoid contacts that results in a no-crank condition. Replacing the starter is a common repair, but a rebuilt unit should cost less than 250 bucks unless you're paying a mechanic to replace it.
