if you dont have voltage at the switch then most likely its not turning the computor on ??? do you mean you have no 12v coming to the switch, check for a bad relay or main fuse

Check the underhood relay box on the left fender well. There has been a problem with corrosion in some of the relay centers. Seperate the box halves so you can see the wireing that goes to the fuses and pull some of the fuses and relays and look for green corrosion on the terminals and the relays and fuses.

sounds like a faulty ignition relay/fuse
