Ignition System Help needed

I have a 1984 Coupe GT that just started having a serious problem. 

My ignition key does not turn on power to any accessories or to the starter; I have power at the battery, and to the interior of the car, as exhibited by the dome light and buzzer coming on when the door is opened.

I pulled the ignition switch and attempted to use a screw driver to manipulate the switch to no avail. 

Any help or suggestions are greatly appreciated!

TIA,

UPDATE:

Confirmed faulty ignition switch, as well as faulty starter;

removed/rebuilt starter with no troubles, tests out fine.

Following the directions in my haynes manual, (i know, i know) i removed the steering wheel, turn signal multiswitch, as well as the lock cylinder.  I have come to the following problem:  there is a lock washer holding a spring which keeps the ignition switch housing locked into its location.  As this lock washer is fully circular, and apparently uses the springs' outward pressure to stay in place, i have no idea on how to remove the lock washer/spring combination.

Any help on this would be greatly appreciated.
