car making grinding noise and wont start after new starter and new battery, what could cause this?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If your 2003 Mitsubishi Galant is still making a grinding noise after a new starter and battery, it could be an issue with the starter not fully engaging the flywheel. Sometimes, the starter is misaligned or the teeth on the flywheel are worn down, which can cause that grinding sound. Since it worked fine for a bit, it’s possible the starter isn’t engaging correctly all the time, especially if it’s an intermittent problem. Also, double-check that all connections to the starter are secure and clean.
