Question about 2002 GMC Yukon XL
You turn the key and nothing happens?
The engine turns over normally but takes longer to start?
The later is either a fuel pressure regulator or a bad fuel pump. If your fuel injectors are on the outside of the intake plenum (you didn't specify the motor) your in luck. If you look on the drivers side of the fuel rail you will see the fuel pressure regulator. It will be a round metal part with a vacuum hose going to it. Pull off the hose and see if gas comes out of the regulator. If it does it is bad and needs to be replaced.
If you have Central Port Injection or the fuel system is inside the intake plenum. It will be a little more difficult to confirm a bad regulator but I wouldn't hesitate to replace it as a good starting point. With the upper plenum removed you will still be able to cycle the key to the run position and see if the regulator leaks out its nipple.
