My first thought is the fuel pump has been replaced in this truck and the fuel level float is hanging at the 1/4 tank mark. Fill it up and see how much gas you can put in the beast when it first hits 1/4. If you can put more than 20 gallons
in the gauge is wrong. I've put over a million miles on these Yukon and Tahoe 4 door Models and the fuel pumps are weak links in the fuel delivery system. Good Luck

2003 GMC Yukon XL: Will periodically stall at highway speeds during the summer (Houston hot). Forced to coast (on freeway) to a stop, wait 10-15 minutes for the Fuel Sending Unit (fuel pump) to cool...


Yeah what's you saying is right, and GM is having a big problem with Fuel Pump on such model, I Already saw a 2 Year Cobalt with a Dead Fuel Pump.. ! Best thing is Keep your tank more than the Quarter, Buy a Dealer Fuel Pump not a Jobber one, be sure the strainer is clean in the tank and check if there's any dirt in your Fuel tank ! Check too if there's any Recall about that on your Vehicle !

Yesterday i ran out of gas. I filled a gas can and put gas in but the car still wouldn't start. I have a 2003 gmc yukon denali, i was told by the dealer that the fuel pump may have burnt out. any advice?


i would say the fuel pump went out also here's a easy way to find out put your head down by the gas tank have someone turn the key on if you here a buzzing sound it's good if you hear nothing well get ready to drop that gas tank.

Have 2002 Yukon that won't start if under 3/8 or 1\4 of gas


hi, the banging on the tank is a typical fuel pump scenario , but to last for years is not very likely , i think it needs to be diagnosed to see what's missing when it wont start .

04 GMC Yukon won't start on less than 1/4 tank of gas


have your evaporative emission control system check.sound like you have purge valve solenoid not working or vent valve control solenoid.have it scan.to see which component not working..reason your gas tank expanding. your fuel vapor building up pressure.your purge valve and vent valve open allowing gas vapor from charcoil canister. to be burn in the intake manifold to be burn in combustion chamber.

If I have less than 1/4 tank of gas my yukon won't start.


I had the same problem. I had a few different mechanics tell me that the fuel pump is starting to go out when it does that. The fuel pump is located in the fuel tank, and the gasoline keeps the pump cool and lubricated. When the fuel tank is less than a 1/4 full, the pump is not submerged anymore, and can have trouble sending gas to the engine. My emergency fix was to get underneath the car on the driver's side and bang on the gas tank about three times. It will start up, and will run great unless you turn your engine off. But eventually you're going to need a new fuel pump. Once I replaced it, the problem went away.
