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.

Fuel reset button on 2002 yukon


The reset button for any instrument display tallies ( fuel consumption, average, trip miles, etc ) is located on the sterring wheel. It should be the button on the lower right with the down and back arrow printed on it. Once you display the item you want to reset, hold this button for a few seconds and the display should reset to 0.

Good Luck

2002 Yukon XL Denali Problem: When idling, goes below 500 RPMs, spits and sputters at idle. No check engine light, spark plugs are one year old. Could it be a sensor??


Most sensors will trigger the check engine light, however the TPS(throttle position sensor) or EGR Valve(exhuast gas recirculation valve) could be potential causes. Does this problem only occur at idle? Is the idle normal in park? Let me know and I can try to assit further.

Hope this helps
