What happens when you do this, I think I blew mine, forgot to disconnect the battery, removed old starter, wire sparked between my wrench and the exhaust pipe!! :eek: I didn't have time to check the link but the new starter i tested before i left the autoparts and when i put it in it just makes a high pitched noise and doesnt turn the car over. :beatdeadhorse: :shocked:

Sounds like your battery is a bit flat

Sound like the starter motor is running but the solenoid is not engaging. That should mean the fusible link is OK. The battery cable is attached to the solenoid, not directly to the starter motor. That makes me think you may have fried the solenoid internals given you hear a whine when you turn the key. Did you get a new solenoid at the same time you got the starter??

Always pull the positive battery cable when working on the car. Extreme current draws like shorting out the positive cable can have some very bad effects on the cars electronics!

No, the starter is good. The spark came after i pulled off the old one, before i put on the new one. I had the new one tested after i put it on on a bench, and it worked fine. Now i have no idea why it wont start. :mad

Yes, the solenoid is new it came already installed on the new starter.

The large red cable going to the starter motor does not have a fusible link. If you short this cable you will get all the current the battery is capable of delivering!. It is safer to remove the negative cable on the battery when you work on your electronics. This is due to the fact that removing the positive cable, your wrench could touch ground and cause large current to flow. The solenoid is a high current switch that turns on the starter motor and also engages the starter spur gear to the flywheel gear. If your starter motor runs and the engine isn't cranking, then the starter spur gear is not engaging with the flywheel gear.

Ok, i figured it wasnt engaging the flywheel....now the question is....what is the car side of that which would prevent it from starting?? The starter tested fine on a bench so it should be ok

Pull the starter and look in the starter hole and at the flywheel. You may have missing teeth on the flywheel, so the starter spins rapidly because it has no load.

You just need to shim the starter to correct the engagement of the teeth.

You'll need to installed starter shims between the block and the starter.

Sometimes it only calls for shim(s) under one side and other times it may call for shims under both.

Starter shims are available at most auto parts stores, or you can just use flat washer(s).
