    I have the same problem on a 2002 Denali XL. Steering wheel is unlocked and will turn both ways. No previous problem with ignition switch.....all of a sudden neither factory key will turn. Gear selector is in park and locked.

    I have a 2003 Yukon. Same problem. I adjusted the wheel direction as was recommended, but it did not change the situation. My repair shop (Dealer is out of business now) has seen this on other GM trucks/SUV's. They plan to remove the ignition switch and have it checked by a Locksmith. I will report back.

Make sure the wheels are straight.. if you park them with them turned to one side the steering column is under a bind.... if they are turned all the way to the right you will for example have to turn it a little to the left to release pressure as you turn the key...

Yesterday i ran out of gas. I filled a gas can and put gas in but the car still wouldn't start. I have a 2003 gmc yukon denali, i was told by the dealer that the fuel pump may have burnt out. any advice?

i would say the fuel pump went out also here's a easy way to find out put your head down by the gas tank have someone turn the key on if you here a buzzing sound it's good if you hear nothing well get ready to drop that gas tank.
