Drop off the steering coloum trim and test that the ignition switch is actualy switching, do this with a tesst light, the easist way is probe each terminal as you turn to ignition on and it should light up, one will be acc feed and one will be ignition and then you will have the cranking circuit that will light up when you switch to crank.

Can be a few things but best to start at the switch and work down the circuit as that way nothing can be over looked.
