Re: Grinding noise when trying to start car.
Hello first thing you need to do is take your starter out the starter drive gear either has busted teeth or the flywheel does with the starter removed mark the flywheel with chalk crayon so you no were you started from look at the teeth good keep turning the motor by hand checking till you come back to the original mark you made if there are no chips or missing teeth look at the look at the starter drive teeth there most likely busted or chewed down replace the starter goodluck please rate

if its a grinding/knocking type sound then it could be the cv joint gone bad.the side that makes the noise when you are loading during turning(turning left you are loading the right cv joint and vise versa)that is the side the bad joint is on.it will happen whether or not your foot is on the brake.if the noise happens as strickly a grinding noise like when brakes are metal to metal when applying the brakes then it could be brakes need replacing.also have seen were if the inner fender is loose or oversize tire is on it can rub sounding like grinding.
No idea what the problem is either. I have a 04' LT that started doing it as well. Doesnt matter hot or cold, does it randomly. Usually when I come to a fast stop then resume speed its sounds like grinding in the dash and while hitting the gas I get NO acceleration, let off for a second then its good. Its happening more often now than before. Does anyone have any ideas?
that sounds correct what happens is the starter still tries to engage the flywheel and grinds the teeth off both. Replace switch then worry about starter flywheel if it starts fine don't worry about it you may have saved it if you didn't let it run that way long
