I have a 97 Monte Carlo. About a week ago car would not start, had lights but no start. Turn over was a little slow, checked battery cables one seemed a little loose, car started. 2 days later would not start, not turning over, no lights nothing. Didn't do anything walked away, next day tried it and it started. Ran it for two days, third day again would not start, tried to jump start clicking noise and the running lights came on, would not start. starded right up this morning, didn't do anything. Daughter drives car and afraid shes going to get stuck somewhere any ideas?
