SOURCE: the ignition won't turn for a 2003 gmc yukon denali

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...

Is the check enigne light on?

If not then it could be a trans issue. Check the fluid again to make sure it is level. put the truck on level ground and with it running and in park check the fluid. Add fluid if needed to bring to level. Then test drive. If it still does the same check the fluid level after driving to see if it REALLY hot. If so it could be a sign the tranmission is failing.

Onyl other thing i can think of have you replaced the tranmission filter? if it was really clogged up it may, long shot, cause what you are saying as well.

SOURCE: lost reverse on GMC Yukon Denali vortex drives

WOW sorry to hear that.

this is a common problem with the 4l60e transmission, what has happend is the gear has sheared off the back of the sun shell, you should have lost reverse and if you will watch your tachometer the next time you drive you will notice you allso lost forth gear.

you will nedd to have the transmission removed and disassembled for the new sun shell, make sure you get the hardened sun shell, this is not a rebuild but simply a repair. you can get a stock sun shell for about $65.00 or a heavy duty one for about $100.00, make sure you find a good tranny guy to provide the labor, oh the transmission paper rubber kit "reseal kit" shouldnt be more than about $80.00

good luck

SOURCE: 02 yukon denali security light stays on will not

Several GM products, including the Chevrolet Impala and Malibu, the Oldsmobile Alero, the Pontiac Grand Prix, and Saturn Ion, have issues with the Security light coming on. This is many times an indication of a failing Body Control Module (BCM). Initially, the Security light will come on then go off, progressing to a constant on light, before the car will refuse to start. Other symptoms may include erratic action of electronics, a clicking sound coming from the glove box, and the air conditioning failing to blow cold air. I recommend a shop that specializes in the electronic systems of vehicles to diagnosis and make the necessary repairs. They should keep the car until they replicate the symptoms described. A new BCM from GM should cost about $230; plan on another $200 for them to diagnose the problem, replace the unit, and program the new unit. The dealers quote between $700 and $1,100 for the same repair. My experience and the experiences I have read on the internet, indicate the new BCM should last only about a year.

SOURCE: Ran out of gas. After adding gas, GMC Yukon XL

Under the hood in the fuse box you need to check two fuses, PCM1 and PCM B. If both of those are fine the next step is to look at the right side of the engine along the fuel rail. Tiy;ll see a black cap. Remove the cap and turn the key to the on position and then press the valve inside to see if there's any fuel coming out.

It's quite possible the fuel pump burned up when you ran out of fuel. When you turn the key to the on position can you hear the pump activate and send the fuel to the injectors for initial start?
