maybe your collum has messed up like mine, take the panels off the bottom and loosen the ignition switch try pulling it towards you and maybe itll start, if anything just to get it on the road you can wire up a toggle switch to the starter on wire to the battery on the posative and the other wire to the s terminal(the small one on starter) youd be able to turn the power on with the key then hit the toggle to start it and youll be fine but id check out the ignition switch for sure, could be the rod in the collum has messed up sounds like the same exact problem i just had with mine good luck man.
