Dead battery? poor battery connections? Remove the battery connections and make sure they are clean and tight. If you do that and it still doesn't turn over, then charge the battery and try. If it still wont turn over I would have the battery tested. If the battery tests good then begin to look at your starter. If your starter tests good, then it is time to look at the ignition switch.
