My 96 chevy Blazer wont start but the bat...

Your pendix on your starter might be stuck, lay down under blazer and tap on the starter with the handle of a srew driver or a small hamme to see if it frees the pendix. You may have a faulty starter. You can jump the starter with a screw driver to see if it works, but if your not familar with that I don't suggest you try that.

the first thing i would do is check your cables.... many people replace starters and alternator when the root of the problem was actually a bad connection at the cable
