There is a vacuum leak in the shut off circuit. Remove all molding around your ignition switch. As you look at the bare unit, you'll find two vacuum hoses. Check to see if one has come loose, or is clogged. Repair or replace as needed. Another way to stop the engine is to press the "Stop Engine" tab on your throttle "venturi" linkage (over the valve cover).

This can be caused by a few different things.The first item to check would be the alternator. There may be a feedback to the ignition switch from the voltage regulator field exciter wire. The other scenario that we commonly see is feedback from an aftermarket ignition system that utilizes an internal relay, or both a battery and ignition source to power the system. These are fairly common problems that people experience when using many aftermarket-wiring systems. Generally, an OEM harness will not have the problem of alternator "run-on", as there is usually a resistance wire in the dash harness to keep this from happening.
Solution: To figure out where the problem exists, start the car and with the key in the ON position and the car running, turn off the key. With the ignition turned off and the car continuing to run, simply remove the plug from the alternator (DO NOT TRY AND REMOVE THE BATTERY POWER WIRE FROM THE POWER STUD!) and the car should shut off if the alternator is creating the problem. If it does not stop running, your feedback problem is coming from something other that the alternator. If you are using an aftermarket ignition unit, check to see if there is a fix available that includes a diode to put in line on the ignition feed to keep their system from back feeding into the ignition switch. If you do not have an aftermarket ignition system in your car and it continues to run after pulling the alternator plug, you'll want to call tech support from your harness manufacturer for help. If your car does shut off when you remove your alternator plug, you may have to put a diode in line on the field exciter wire to keep the alternator from back feeding to the ignition switch. Again check with the harness manufacturer for help.
It could be a couple of things. Try finding out which relay is clicking by touching the top of each relay. You'll be able to feel the click. The lid to the fuse box should have a diagram of what each relay controls. If the fuse box doesn't have the information, your car's manual will have it. In the back, look for "Fuse."
Check and make sure the ignition switch is not worn out and allowing you to remove the key when the switch is turned backwards in teh accessory position. once the key is removed and the radio is staying on, turn the ignition without the key in it, both directions and see if it shuts off, if it does, menas work cylinder or key.
Pull the 60amp fuse in the fuse box near the battery. You'll find it. That will shut off the motor. Remove the neg ground on the battery to shut off the rest of the car and save the battery,
It sounds like the ignition lock actuator. It goes from the ignition key switch to the Yellowish ignition switch box, under the dash on the column. It pushes the ignition switch to start and pulls it back to stop and lock. If you remove the 2 hex screws on the yellowish ignition switch and let it hang down, you will see a rod sticking out of the top. It's a slider. Push the slider toward the engine and it starts. Toward the drivers seat, and it shuts off the car. Check this out. http://en.allexperts.com/q/Steering-Column-Repair-2047/2009/7/95-Thunderbird-1.htm
