Question about Cars & Trucks
Sometimes new starters have to be shimmed so that the gear on the starter lines up with the gear teeth on the flywheel on the motor. The grinding noise is the reason I say that is what's wrong. If there were shims already there, try taking them out. I hope this helps you

My guess would be the anti theft security system. When this system starts to fail, it turns off the starter from the ignition. The fact that you can hard start it proves this.

The fact that a jump made the thing work really rules out starter and solenoid. If you got a clicking but no start, then a jump fixed the problem, there are really only 2 possible causes. Since the first is a dead battery and you have said the battery was fine, then it has to be the second, which is a poor connection between one of the leads and the battery. Sometimes, oxidisation builds up under the connector and this will cause the connection to fail although it looks good. Clamping jump leads to the connector probably disturbed it and made the connection good again. Remove each cable clamp, clean battery connector and the clamp on the cable thoroughly with emery cloth and reconnect, As you're doing this, also check that the connections that hold the cable into the clamp are good and tight and have no corrosion.
REMEMBER that if you disconnect your battery, you may loose the security code to your radio/CD. An easy way to avoid this is jump onto the cable connectors from another battery (Like you were jump starting it) so that the power to the radio is maintained during the procedure.
