2003 yukon stalls in traffic

My 2003 GMC Yukon XL occasionally stalls in traffic, sometimes even on the interstate. After a few attempts at cranking the engine, it will usually start up again, and run fine for several more minutes, hours, days, or even weeks. These episodes are becoming more frequent (in the past few days), and have even happened while at idle. My guess is that its fuel-system related, but where should I start? I tend to search out the cheapest gasoline prices, and fear that my frugality will prove an expensive mistake. Are their any fuel additives that might be useful at this point? Any other advice or suggestions will be most appreciated.

Are your rpms at idle low? If so, remove and clean your throttle body with throttle body cleaner i.e. Gummout carb and throttle body cleaner. This will return vehicle to original factory rpm levels.

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.

2003 GMC Yukon XL blower fan intermittently doesnt turn on


Could be the blower motor, the resistor, or the control on the dash.
You'll need to check the circuit for voltage when it fails to work.

2003 gmc yukon died now the ignition is locked


Sometimes on GM vehicles, the anti theft system can fail. This causes the car to stall and can lock the ignition to prevent theft. If you see a light on the dash that says "security". Then this is your problem. Info and solutions on this site. http://vatspasslockpasskeysecurityhelp.yolasite.com/

I have a 2003 yukon Problem with the GMC Yukon XL


What size engine ? 4.3 L vortex P0300 random misfire code is usually associated with vacuum leaks , but could also be low fuel pressure , plugged fuel filter , fuel pump problem , clogged injectors etc... doing fuel pressure an flow testing would confirm or eliminate that as a problem . Fuel injector balance testing would confirm or eliminate clogged injectors .

Suddenly stalled in traffic, gas was low but I dont think empty. Added gas would crank but not start. Alternator pulled and tested OK. Still won't statrt seems to not be firing.


spray WD40 into intake, if it acts like it wants to fire, it is a fuel problem, more then likely the fuel pump. Now if it doesn't act like it wants to fire then it is in the ignition senor, distributor. Hope this helped Tim

How do you reset the check engine light on a 2003 gmc yukon xl


the check engine light means you have a trouble code in your vehicles computer. After fixing the problem with the yukon the check engine light can be reset sometimes by disconnecting the battery and disconnecting the ECM fuse. Although some parts stores are known to check your codes for free they might also clear them with a scan tool.

I have a 2003 Yukon XL 1500 with the 5.3L engine. Twice in the last week when I was on the Interstate and had the cruise control on the vehicle unexpectedly stalled and I had to guide it to the shoulder....


there are a few causes for this to happen
I just put a fuel pump in yesterday in a 04 yokon XL with the same issue
it had a plugged fuel filter, and low fuel pressure.
Same complaint, coming from CA to TX, freeway speed cruise on and it just dies.

The vehilce needs to be looked at, and have vehilce scanned for codes.

I hope this helps.
