Pull the starter and growl it. Pull it out and place a negative wire to the bolt hole and use a positive wire to hit the positive post.
Hold on to the starter when you do this as it will jump off the work bench.
If it turns freely, start to worry. If it does not turn, visit the auto parts store and get a new one.
AND MAKE SURE THERE IS A GROUND STRAP BETWEEN THE ENGINE AND THE CHASSIS.
If the starter turns freely, go to the engine and place a socket and wrench with a long breaker bar on the harmonic balancer nut. Turn the engine over.
If you can turn the engine over, take the starter to the auto parts store and have them do a current draw check.
If you can not turn over the engine, it isn't the starter.
I hope this helps.
