Question about 2006 GMC Yukon Denali
I would first suspect the mechanical ignition switch, mounted on top of the steering column by your feet. First remove the splash panel under the steering column.Mark the position with a marker or scribe - it's very important that you re - install that switch in the EXACT position it came from ! Remove the retaining nuts ( or bolts ) securing the steering column to the dash. Carefully lower the steering column - on the top side you'll see a rectangular plastic component with a wire harness on the left ( driver ) side and a metal rod out the back side coming toward the steering wheel. Dismount that ( it's the mech. ign. switch ) and unplug that harness. Inspect the plug for corrosion, burnt blades or rust. clean up any dirt and put dielectric grease on all blades / connections . SMELL the switch - if it smells kinda burned, replace it. If it's not stinky it may still be going bad. When you re - install, check operation of the switch before you remount the column. That metal bar activates the starter, and if the switch is too low your starter won't engage. Also be VERY careful with that airbag - a shock or hard bump to the steering column with the key on could deploy the airbag, potentially causing a serious injury.
Maybe take it to a shop and let THEM have the fun,heh?
Hope this helps!
