ok so the top bolt of my starter fell off and my starter eventually backed out of the starter housing... i turned the key, made the sound a starter would make if it wasnt connected to the flywheel... so i put it back on in hopes that it still works... start it up, cranks but doesnt start... so i go a get a new starter and put it on... crank it.. it turns but wont fire and now its making like a clunking feeling/noise... i got another starter and it did the same thing.. any opinions?
