Question about 2006 GMC Yukon Xl Denali
Do you have any lights lit on the dash , SECURITY , check engine ? I wouldn't think fuel pump fuse , if it were bad it would start at all ! Sounds like anti-theft system problem !
The theft deterrent system has been incorporated into the body control module (BCM). The theft deterrent is provided in order to prevent vehicle operation if the correct key is not used in order to start the vehicle. The ignition key turns the lock cylinder. The cylinder rotation produces an analog voltage code in the Passlock?"¢ sensor. This voltage code is received by the BCM. The BCM compares the voltage code to the previously learned voltage code. If the codes match, a class 2 message is sent from the BCM to the powertrain control module (PCM)/vehicle control module (VCM). The message enables the fuel injectors.

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.
The ohter is under the dash and above the pedals, this one is much tougher to access.
Your Owner's Manual should tell you where the fuses are that you need to access.

it has to do with your air ride suspension best bet is take it to the dealer there is probably a problem with a level sensor. hope this helps you

Your sending unit for the guage is part of your fuel pump in the tank. But first try your fuel pump relay, may be working intermittenly when you hit a bump or something. Or possibly a loose wire somewhere along the way. Much less expensive (worth a look).

Could be the latch mechanism for the door is sticking. You could try using some white grease on the latch and the contact where the latch hooks to. You can purchase the grease from most auto parts stores. You will not need to use alot. Just apply a small amount to the mechanisim and then work it in using the manual handle. Then open and close the door several times to feel the "action". Then apply a little more and repeat. This should loosen the latch and get it working again. Also make sure that none of the tension springs have come loose on the latch. And check the seal around the door and make sure it is not pinched and has a proper fit.
