Oldsmobile Bravada Problem

Visitor, 2001 Oldsmobile Bravada
intermittently the car will not start. Full power to everything but no noise or crank. I lock/unlock with the door switch and it usually starts, sometimes a few min... sometimes longer. now it will not start at all. I was told its the ignition switch.

Truck will turn over fine,and when it starts, it runs fine.
When key is on "run" position, the dash lights will only come on 1 out of 10 times. If the dash lights come on, it'll start. if not, it just turns over. Repaired once by replacing entire steering column (easier than digging past the airbag to get to the ignition).
