When you turn the key on will the radio work? If not since the radio is "switched" the actuator pin in your ignition switch is probably broken. If it works then there is a good chance you "real" ignition switch, what the pin turns, is dead so the ECM is not being "told" to tell the starter to crank. See viewtopic.php?f=5&t=61233&p=678574&hilit=+brother#p678574 FYI both of those parts have aftermarket options.

geordi's post on the neutral switch reads "Pull the shield off the top of the gear shifter, there are 2 small cables in there; the passenger-side one is the sensor cable, it's not electrical, it's an aircraft wire; the sensor is actually located under the steering wheel. Unhooked, problem solved permanently. I thought of a quick way to test the actuator cable without pulling anything apart on the shifter console - With the engine off and in park, pull back slightly on the shifter to apply tension, and try cranking the engine. If it doesn't go... The cable is the culprit b/c the tolerance (and how much it moves normally) isn't much. The cable is pushed toward the front of the vehicle when the selector is in park, and just shifts backwards slightly when the selector is anywhere else. All you need to do is unclip the end of the cable, and push the end into the sheath until it stops (about 1/4") and tuck it away in there. This won't affect anything else in the operation of your CRD, the shift interlock (that foot-on-brake-to-shift) idiot switch will still be there and functioning... Unless that 2-wire connector happens to "fall out" like it did on mine. Strange how that happens sometimes. "

Thanks guys but most of the credit is due to other forum members. I just try to keep a personal file of past solutions for when the problem happens again. I will add to that a bunch of years messing with cars and a personal preference for looking for the obvious simply solution to the problem first are both a help.
