Look for a crank sensor near the crank shaft:

Crankshaft Position Sensor Operation Engine speed is an important input to the Engine Management System (EMS). Crankshaft speed and position are the basis for many calculations made by the computer. Crankshaft position values are transmitted to the computer by pickup coils also known as Permanent Magnet (P/M) generators, Hall Effect sensors or optical sensors. The Crankshaft Position Sensor (CKP) also known as an engine speed sensor is typically located in close proximity to the crankshaft.
In addition the EMS uses the CKP sensor in conjunction with the camshaft position sensor to calculate and perform misfire diagnostics.
Related Symptoms

  • A No Start / Intermittent Start condition – Can be caused by a faulty crankshaft position sensor due to loose connections, bad grounds, high resistance in the circuit, or opens in the circuit.
  • Engine Misfire Diagnostic Trouble Codes
NOTE: Engine Mechanical conditions can also create the same or similar symptoms. (Don’t overlook basic mechanical integrity).

SOURCE: 2002 GMC YUKON XL 1500 MOTOR DIES AFTER GOING

Check the fuel cap!! If the vacuum relief is not working it can impede the fuel flow and cause the engine to shut down or not restart after a stop. Waiting usually gives things a chance to stabalize and the engine will restsrt. When this happens again try loosening the cap and see if the engine will restart.....If it restarts immediately, REPLACE the fuel cap..Do Not leave it loose because this will cause other problems. If it is not the fuel cap the problem may be the filter, the fuel pump, or aome other fuel system malfunction.

Most likely the rheostat on the float is bad. Unfortunately, this is part of the fuel pump and inside the fuel tank.

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!

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.

Cranke sensor


It's down, behind the crankshaft pulley, on the passenger side of the motor. It should have a 3 wire plug and a 8mm bolt holding it on.

Girlfriend's 2002 Yukon will crank but then occasionally RPM's will drop and it will almost die. Replaced O2 sensors but ... still occurring?


Look at the mass air sensor next to the air filter, check to make sure the clamps are tightend and it is properly sealed. Quick oil change places ar famous for not putting it all back together properly after checking the air cleaner.
