SOURCE: yukon wont start

Ok. sounds like you have already replaced the most likely suspects, but let me ask you a few questions to see if I can help you. When you try to start the vehicle is it firing? Do you have fuel pressure getting to the injectors? O.K. this next question will sound a little strange, but it will tell me if the computer control system is working. When you try to crank the vehicle, does the RPM guage move at all while engine is spinning? Let me know the answers and I will try to help you.

Check to see if the power steering pump is still turning. If you have a broken drive belt (serpentine belt or "fan" belt), and the pump doesn't turn, you have no power assist. If the pump is still turning, check the fluid level in the reservoir.

FROM: LustyKid

Denalis are famous for clogged fuel filters. Change the fuel filter first and see what happens, Get the code for the check engine light. It could be you have a clogged EGR ports. Remove EGR valve and clean out the ports, replace with new gasket and see what happens. Advise of results.

SOURCE: service engine light staying on

Hello tdamm...No...the service engine soon (SES) light on your yukon is not telling you to change the oil.
This is a warning light that is illuminated when there is a problem affecting the Emission system and the engines computer management (ECM) has detected it from a fault. It could be something as simple as a loose or defective gas cap. If the SES light is blinking, it's more serious....
The yukon needs to be connected to diagnostic equipment (scanner) for fault diagnosis.
You can go to autozone they will hook up an OBD II scanner to your vehicle and explain the codes to you.
Good luck...i hope this helps and will fixya up.

SOURCE: yukon xl 2003 when i turn air on sometimes it wil

It sound like your air idle control valve may have gone bad or the wire harness has unclipped. The common problem is the air idle control valve has carbon build up. Try spraying Throttle body cleaner, (NOT CARBURETOR CLEANER)in through the throttle body. USE the whole can, just follow the instruction on the can. Once that has been done, turn the engine off, turn the ignition key to the run position for 30 seconds and then turn if off for 10 seconds then start it and let idle for 1 min and go for a test drive. If it's still stalling check all the wire connection to the air idle control valve and try cleaning it again. If that doesn't work then your going to have to replace the air Idle control valve. Try cleaning it first the cost of the control valve is around $100.00 give or take and most dealers will try cleaning it first before they replace it, since they know you'll be back for it to be cleaned again in the future telling you they manage to save you some money buy cleaning the one you have. Good luck and hope this helps.

Do you mean the truck doesn't start or doesn't move? If no start does it crank or no crank if so check the starter maybe the wires are not conected if it doesn't move check the 4x4 if equipped make sure the transfer case isn't in neutral look at the switch on dash and select 2wd

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.

My 2004 yukon xl wont start


You need spark at the right time, fuel pressure at the injectors, and normal compression.
Have the spark plugs been changed in the past couple of years ?
Have you checked the fuel pressure to see if it is enough ?
Have you sprayed carb cleaner into the throttle body to try to make the engine try to start ?
Does it sound like it has normal compression when cranking ?

My GMC yukon XL 2001 engine runs after 4 times of cranking.


Try turning key to on only, not start, 2 or 3 times first then try to start. If it starts good first try, then I'd change my fuel filter & then have fuel pressure tested if fuel filter didn't help. You may be looking at a new pump, but lets do filter & test fuel pressure first.
