Hey guys I have a 2002 Chevy Cavalier that is my daily driver, went out to start it the other day and it wouldn't turn over, so i took my jeep instead, today I had my dad take it to the shop because we couldn't figure out what was wrong with it. I just got a call from the shop and they said after it got off the tow truck it started right up and has ever since, anyone have any ideas as to why this might have happened.

I checked the fuses for the starter etc.
I checked the connections to the starter
as well as i hit the side of the starter with a small rubber hammer,

thanks again for your help,
