Starter Solenoid stuck open and it now acts up:

[meliketoball]

My starter solenoid was stuck open while I was driving.

I drove with the solenoid stuck open for about 30 mins until I got home.

The car backfired and I felt a power loss.

I popped in a new starter and now when I turn the key, the starter turns slowly and grinds against the flywheel.

I replaced the new starter with a new one, checked all connections, and changed the starter relay and it still spins slowly and grinds against the flywheel. It still starts and turns over, but is unreliable. Today, I tried jumping the car, but to no avail.

I am currently charging the battery, any suggestions?

Did you inspect the flywheel teeth when you replaced the starter. Your flywheel ring gear may be trashed... Which if that is true, it probably trashed your new starter also.

Flywheel teeth are fine.

I put in a new battery and it cranks faster, but the starter grinds against the flywheel when the solenoid is engaged.

I am suspecting that the starter plate is bent.
