Sounds like it's time to get the volt meter out and make sure everything that should be hot is working. I think those red wires have fusable links on them so make sure oyu have voltage at the starter then make sure it's getting to the fuse box. If not there could be something in the switch not working.
But is the voltage making it to the fuse panel when the ignition is turned on?
No voltage to the fuse panel is a different problem than the ignition switch not turning the motor over. There is a small wire in the same harness, I think it's purple, and it goes to the starter solenoid. This wire also may not work if the steering column section down by the instrument cluster isn't in the proper position. The reverse lockout could be keeping it from starting.
