#30 of 48 wont start unless gas is added to carburetor by john8009 May 14, 2009 (8:14 pm)
My 1992 yukon wont start unless you add gas straight to the carbuertor. It will run fine after that but as soon as you turn it off you can't start it unless you readd gas to the carburetor.

Replying to: yetirider (Feb 27, 2009 8:24 am) Hi Yetirider, I just purchased a 2009 gmc yukon a few days ago. On the second day my wife was driving it and while attemping a slow left turn the vehicle died and she then pulled to the side of the road and it started right up. She was driving it today and it did the same thing. I drove and it did have some hesistation to it. I called the dealer and asked the service advisor if he had heard of this happening and he said know. I will take it in this week for a diagnostic. It sure doesn't look promising since I am already having problems. A vehicle that dies on you while driving is very dangerous. Will let you know what they find.

I never had that problem and I had my yukon for 9 years now. If it continues, under the lemon law you qualify to receive another vehicle at no extra charge. My expertise would have to say there is something going on in the brians of the operation so have them hook up the computer to the Yukon and see what it says. It could be lots of things i.e. fuel injection, electrical , or computer telling everyone else to shut down because of something you know? I hope this helps and I know its frustrating especially when you just spend lots of money supporting an icon like GM and this happens.

Replying to: yetirider (Feb 27, 2009 8:24 am) I have had the same experience with my 02 yukon xl (108,000 miles). Recently on two(400 mile) trips the truck stuttered and stalled while driving. After sitting for a few moments the truck started and ran fine. After the the first occurence, I replaced the wires, spark plugs, and fuel filter. A week later the same thing happened. Any ideas???

#34 of 48 mass air meter unit by fongerelli Jul 20, 2009 (7:52 am)
I have an 2000 Yukon (with the new body style) and I have 102,000 miles on it. I have never experience that yet, But I had the similar situation with my Jag, It would stall at an idle, and it started up after I tried but you had to baby the gas pedal to get it going again. You might want to check out the mass air meter (expensive 300-500) or go to a junkyard, because once I replaced that in the Jag it was normal again. Back to the Yukon, I have never had to change the Mass Air Meter in it yet but i did put a chip in it to get better gas mileage or so they say. I have a feeling that GM installed a sensor device that once you reach a certain mileage it starts to stall and etc.. Once you know how to reset that portion you should be fine. If you hooked up a computer to the Yukon system it should indicate the issue that you have, I hope? Look at all of your filters too and make sure the system is running without any obstacles in it's path.

Replying to: coach17 (Aug 01, 2009 5:28 pm) check your mass air sensor or your control valve sensor or have your throttle body cleaned. Let me know.
#38 of 48 2000 Yukon by chicks100 Aug 18, 2009 (8:48 am)
Yukon dies while driving, no sputtering, no stalling, just dies. Runs fine after restarting. Any suggestions to the problem??? Replies to this message: rcortez (Aug 18, 2009 6:54 pm)
