I am not familiar with the 2002 but I was able to find this http://www.justanswer.com/car/0j00x-last-time-drove-2002-gmc-yukon-xl-security.html Since I have a 99 I can't test it or guarantee it will work but it is worth a try.

Jose, when you try to turn it on your yukon does it turn over or not? If it does turn over and it doesnt cank it could be 2 things the starter or the cam position sensor

The security light was on because you had your door open or ajar.

How do you know there is no fuel pressure? How did you check it?

Check your Fuel Pump Relay.

#1 yes it turns over and crank the engine but it will not start
#2 the doors are all closed
#3 i check the noise that the fuel pump normally does and nothing i check the fuel pressure with a fuel pressure gauge nothing i check the relay and no power (battery is good ) i dont know what else to do

one other thing is that all the gauges work on the dash except the gas gauge it does not move at all and yes there is about half tank of gas

Put a new fuel pump relay in and if that don't fix it you have a bad fuel pump.

chances are one of the other relays next to it are the same. if so, swap it out and see if you hear the fuel pump kick on.
