No start! everything else works. Help Me

[2010LTZ4x4]

Maybe I'll get better luck in this section.

 

Its a 1999 Chevy Tahoe and it went in for service cause it wouldn't start unless you played with the gear selector then start the truck in neutral.

Got it back from the shop and they replaced the ignition switch, worked great for one day now it won't start unless you hit the steering wheel than it fires up. I phoned the shop and the first thing the mechanic asked is if I had tried hitting the steering wheel.

Does the ignition switch have adjustment to it?

Thats why it needs to be hit first before it starts?
