2000 Mazda MPV Grinding Start Noise
Suggested Repair
Remove the starter and inspect the starter and flywheel teeth. If the starter teeth are chewed, replace the starter. The starter is more likely than the flywheel; if the flywheel is damaged, the starter may eventually fail to engage and the flywheel will need replacement.
Conversation Summary
The owner of a 2000 MPV reports occasional grinding when starting, similar to cranking an already-running engine, followed by a no-start; another attempt usually cranks normally. They ask whether this indicates a bad starter and whether continued use could cause more damage if the flywheel is at fault. The expert says it could be the starter or flywheel, recommends removing the starter and checking the teeth, and suspects the starter more than the flywheel. If the flywheel is bad, the starter may one day fail to engage and the flywheel will need to be replaced.
