82 911SC. Was having an intermittant starting problem, but now will not start at all. Turn the key, and all guages light up, seat belt buzzer buzzes, and all accessories work. Used to be able to turn the key several times, then it would crank & start. New High Torque starter installed approx 2 yrs ago. Just replaced the electrical portion of the ignition switch, and still nothing. Tried turning the ignition switch with a screwdriver, to rule out the mechanical part of the ignition switch. Still did not crank.
