Question about 2002 GMC Yukon XL

1 Answer

Our 02 Yukon xl 1500 will die going up hills.

On a camping trip we were heading down the highway at 65 pulling our camper when the engine just died. Pulled over and waited 10 seconds and it started back up. We made it to camp and while there had the fuel filter replaced and the fule system cleaned. We had no problems on the way home but we now just returned from another trip pulling our camper and it died several times going and on the way home and it seems that it occurs when going uphill only. It always starts back up after sitting for no more than 10 seconds.

You need to have the fuel pressure tested while driving and this can be done, and with the gage. I hook up the gage to the fuel valve and put the gauge facing the windshield and wire tie it to the wipers to see if the fuel pump is bad, if the fuel pressure ranges at 30 PSI I would put a load on it to see if the fuel pressure dropped under those conditions you are driving. I would also test the fuel pressure regulator to see if it gave full fuel that means pulling off the hose and making the fuel rail pressure 50 pounds per square inch. If the regulator passed the test then I WOULD SUSPECT THE FUEL PUMP HAS QUIT. A 2002 is old enough to have this happen they wear out so I hope this helps and gives you an ideal of what to fix.

What's your problem? 2000 Yukon XL Yukon died while driving down the highway like it ran out of fuel. Had 1/4 tank. No fuel pressure.


You'll need to check the circuit from the fuel pump relay back to the pump. The computer grounds the relay.
If the pump is running the filter could be clogged.

Does the trany fluid smell burnt? Might want to have the trany flushed - torque converter too - and replace the filter in the trans. FYI you may know this but it is not recomended that overdrive be enabled when pulling a trailer - especially a heavily loaded one. Does your town have lots of hills - this is an added stain on the trany.

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.

If the scan will narrow down which o2 sensor it is and replace it. If it has more than one on that year that is. Under load you will probable have a richer fuel mix. If the sensor is going going bad it may only get out of spec reading under heavy load and warmer temps. I have had similar issues with GM and it was easily fixed.

Sounds like a possible fuel pump problem...When they begin to go bad they will overheat and lock up, then work fine for a while and do the same thing again. By changing the filter you lowered the flow resistance and allowed the pump to work a bit easier but still being bad, it did the same thing again. There are other things that can do this as well, but pump is most common.
