If I had a computer in my back pocket I would throw it in as a test, but the next best thing is to eliminate all other likely possibilities before finding another one. First measure the voltages on the pins I mentioned previously. Pin 46 must have voltage all the time, and pin 20 must have voltage when the ignition switch is in the "run" position. There has been a lot of trouble with overheated contacts in the ignition switch and with overheated terminals in the connector and the connector body melts, but that typically affects the heater fan / power windows circuit. I don't recall ever replacing a switch or repairing the plug for a no-start condition.
If you find 12 volts on both of those wires, we should check the ground wires next to be sure they all have 0 volts on them. If it comes to that, I'll dig out the service manual and figure out which pins to measure on.
