Replace starter if engine won't start and you getting a noise from the starter and the starter checks out ok but still makes a spinning noise what's happening

Is the engine turning over with the key in the start position? If the engine is not spinning over and you hear a whining noise, the starter is not engaging the flywheel. If the engine is turning over with the starter engaged, the engine has most likely jumped time that creates low or no compression which results in the whining noise.

The clicking noise is the starter relay, which sends power to the starter. sometimes the relay is mounted on the starter, sometimes on the fender. I would say the starter is bad and needs replaced. Sometimes you can get a bad starter from the factory. Just because its not that old, or even brand new, doesn't mean that its a good working starter. Replace that starter.

I think you have damaged valves but no make and model stated

If it won't crank in neutral, you'll have to get someone to scan the computer for trouble codes, and check the starter cable for power.

take a obd2 code scanner to have a check.

If the starter motor is turning the problem may be a broken flywheel tooth. If starter is not engaging the solenoid may be bad or not hooked up but that seems unlikely since starter was replaced. The problem's down there. If solenoid not clicking then problem may be further back.

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

does the motor crank or you just getting a click noise

Check your wires for good connections.

There is most likely a problem with your starter -- if it is not grabbing the engine to turn it over when you turn the key, the starter motor will spin (giving you the whirring noise) but the engine will not move. First things first ... have someone turn the key, and hit your starter with a stick or something ... sometimes this will free up whatever part is not working proper5ly, and you won't have to replace your whole starter. If hitting your starter doesn't work ... and if you are good with cars, try replacing the starter and see if that helps.
Hopefully those will help ... if not, you will probably have to take the car to a mechanic to get it fixed, as there are several other parts that could be causing the issue -- but they are hard to get to and require some experience to know what you are looking for.
