might be a VATS problem. try cleaning the contacts on the resistor pellet, and on the inside of the ignition

definately sounds like vats, the two orange wires on the ignition lock cylender often break, so that the vats system gets an infinite resistance which dosnt match the key, and it cuts power to the starter, ignition, and fuel.
