you might have to ajust the electrical starting switch on the colum under the dash, looks lik this link. i think i used a 1/4 in drive ratchet with a 5/16 socket. you see that the switch has slots and thats where you get the fine tune for the switch. loosen, ajust,try till it works right. worst case the switch is screwed
