2003 yukon xl

Asked by Jun 12, 2017 at 08:57 PM about the 2003 GMC Yukon XL 1500 SLT 4WD

Question type: Maintenance & Repair

Hey guys.. I need HELP!! My 03 yukon idles
rough, and dies when I take it on the road. Itll
drive fine for a while and dies while in gear.
It'll start back up after a while. When im
trying to get it started again it will start and
idle, but die when i press the gas. Again after
about 10 or 15 minutes of trying itll start and
go. Ive changed MAF, fuel filter, spark plugs,
wires, and O2 sensor. Any thoughts would
be great. My son has a chance to make it to
state in baseball and i cant chance my truck
not working. Thanks for your time.

Are there any stored codes or a check engine light on? I suspect a bad fuel pump. But it is very hard to diagnose a problem over the internet. Any other info you could provide would likely be helpful.
