The key has nothing to do with the starter turning over. The key can be off and the starter should still turn over the engine. If you completely remove the small blue wire from the starter switch on top of the starter and isolate it; even with the key in "off" the starter will turn over the engine when the foot starter is pushed. Are you sure that you have both voltage and ground to the starter? Many guys run the negative battery cable directly to the lower starter mounting bolt. All that's needed is a +12v at the starter switch post and battery negative to the starter. Try a jumper cable directly from the neg battery post to the lower starter mounting bolt (wire brush it first) and see what happens. Tranny in neutral!
