Question about 2001 GMC Yukon XL

2 Answers

Will not start

I have a 2001 yukon XL w/5.3 wife was driving, engine began to shutter and it died and would not start again. Have had problems for about 2 months with cranking in the morning. I usually have to try twice before it will crank up. Also the service engine light came on today for the first time before it cut off on wife. What can this be? Thanks glenn.

Check your battery, if it is bad it will not run right and the light will turn on
an auto part store will check it and be glad to replace it for you
do not let your them up sell you buy the some size battery that you have know.

Service light can be due to misfiring in one cylinder, discharged battery, or faulty O2 sensor. Start from battery (you can try jump start) to distributor cap/wiring/spurk plugs/alternator. Also check fuel lines (fuel injectrors, filter, pump). If no help check O2 sensor and coolant temperature sensor.
Please kinly let me know if you would need more info
Good Luck

Oil change tech says my idle relearn needs fixing on my 2001 Yukon XL...can my husband do this?


{: ) Anytime the powertrain control module (PCM) or the battery is disconnected, the PCM loses power, or the PCM is reprogrammed, the PCMs learned idle position is lost. The engine idle is unstable when the learned idle position is lost. For a 2001 Yukon XL, you can try these steps: Automatic Transmission
  1. Turn OFF the ignition.
  2. Restore the PCM battery feed. ( IF it was disconnected)
  3. Turn OFF the A/C controls.
  4. Set the parking brake and block the drive wheels.
  5. Start the engine.
  6. Ensure that the engine coolant temperature is more than 80°C (176°F).
  7. Shift the transmission into Drive.
  8. Allow the engine to idle for 5 minutes.
  9. Shift the transmission into Park.
  10. Allow the engine to idle for 5 minutes.
  11. Turn OFF the engine for 30 seconds.
Manual Transmission
  1. Turn OFF the ignition.
  2. Restore the PCM battery feed. (IF it was disconnected)
  3. Turn OFF the A/C controls.
  4. Set the parking brake and block the drive wheels.
  5. Place the transmission in Neutral.
  6. Start the engine.
  7. Ensure that the engine coolant temperature is more than 80°C (176°F).
  8. Allow the engine to idle for 5 minutes.
  9. Turn OFF the engine for 30 seconds.
After the procedure, you can do testing and observations. If unsuccessful, you may repeat the steps.
Also, the best time to relearn idle is after a throttle body clean (from carbon deposits)

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.

2007 yukon xl battery dead recharged battery will not start no security light no gages work when you turn the key on. try to start the engine nothing happen like the security system shut down. can you...


We had the same issue with our 2007 Yukon Denali XL. Died on us twice after sitting for short periods of time; once we watched a DVD with the engine off and battery died within 10 minutes. The dealership kept it overnight to troubleshoot why the battery died so quickly. They said the radio was "pulling" too much from the battery. (They supposably fixed it) But again a few days later the battery died again after sitting overnight. We brought it back to the dealership and they brought in a GMC "expert" to replace the entire DVD/CD/Navigation system. They also replaced our battery with a much larger battery, similar to the ones that GMC puts in there diesel trucks. They had our Denali for 5 days, but it appears to be fixed now.
Getting it fixed correctly wasn't without headaches, but it was all covered under warranty, including the battery. And they are updating the nav w/ the new edition disc as well for no charge.
