Had the same problem. After checking all elec connections I pulled the starter. On the bench and hooked up every thing worked like its suppose to, cranked just fine. Put it back in and it starrted once, but, wouldn't start again no matter what i tried on it. Pulled it out and went to NAPA & picked up a remanf. for 96.00. Put it in and have had no subsequent problems. The old starter was just shorting out internallly when it felt like it.
