When I turn the key to start, there's one loud click and I that's the sound of the starter solenoid(because I bench tested my other starter with the solenoid and it made that same sound). So I beleive the problem does not exist with the starter and starter solenoid. I sanded down and cleaned the ground strap on top of the tranny to body ground(so that's probably not it). I tried running grounds from the neg. batt. post to the motor and tranny casing for more grounds.

What do I need to check next? Could it be an elect. plug or something to do with a clutch restart or something of that matter? Again the motor doesn't turn over just one click of the starter and u can hear the fuel pump kick in but no motor rotation.
