If your cars turns over but will not start you need to check the alternator...once u have done that if it is bad you need to change it. also check the dash light...do they come on for about 5 seconds when you turn the key just enough for the sterio to come one? if they do your battery is fine and it sounds like your starter is fine too...so what i would do is check the alternator. let me know....email is...TristaButt2103@Yahoo.com
