Are you sure the motor is not siezed..if it's ok then check out the following..There should be a "fusible link" between the battery and the starter...The link looks like a heavier wire but that is due to the insulation they use on it...ALL fusible links are 4 wire gauges smaller than the wire they are to protect...Just trace from the pos. side of your battery and you'll see it, it could of burnt out there causing all your problems...you can pick them up at autozone but make sure you replace it with a correct gauge and soldier and tape your connections.good luck
