Where is crank sensor
If you go to Google and type in "2002 GMC Yukon XL Crankshaft Position Sensor"...click enter...then look for the tab that says "images". The first image I found shows the location of the CPS. If you're not able to view the image, the sensor is located on the lower right rear of the engine block.
Good luck!

Could it the water pump
Coolant leaks can be difficult to trace because the leak can migrate away from the source. To start with, dry off all areas that are wet. Then ,with a flash light, inspect the hose and water pump to see where the leak originates. This is done with the engine running so be mindful of all moving parts as you look through the engine compartment. It may be the hose that is leaking.

just fixed this problem, change your fuel pump module, fuel sending unit shorts out on fuel level swing arm blue wire... unfortinately you must replace it as unit because of the design, fuel pump and tank guage fuel level sending unit are a one peice item, fuel tank has to come out to change unit, about a $ 700.00 repair too... fuel pump module runs about 350 to 700 $ depending on aftermarket or factory, try to find one with a lifetime warranty even if it is $ 50.00 more worth it..labor is about $ 250 to $ 400 depending on shop labor rate... definate problem though I ahve no doubt, common problem on GM... please rate my help, thanks...
2002 GMC Yukon XL 5.3 Cold start
What happens if you bring power directly to the starter solenoid? Will it crank then? You need to try to isolate the problem. If it will crank with direct power, the starter is NOT the issue. Let us know what you find.
Minimum rotor thickness
ON most disc rotors the minimum thickness is cast into the body of the rotor and will read min thickness and a dimension. The dimension is also available in the workshop manuals and from the service department of your vehicle. Do not be surprised if you find that your dimensions are almost at do not machine limits as original rotors are not much thicker than the low limit.
