My 04 GMC Yukon will not start or click over what is the problem

SOURCE: '04 GMC Yukon Denali Check Engine Light

Did u put in fuel shortly before the light came on? I own 2 service centers & the most common situation with "Check Engine" lights are because the fuel cap wasn't re-installed or not tightened. When you refuel make sure it "clicks" when putting back on. We don't charge for a "Code Reading" but a dealer will, don't go there. Go, like the others suggested. If it is the fuel cap & you re-install it correctly, the light will go off after a short drive. Good Luck. PS-Don't panic when the "Check Engine" light comes on unless it blinks, if that happens don't drive. PSS-RE: Murray's, Auto-Zone.......If it's a "Code" (the reader will give a #) the code book will tell you the problem. PSSS-Some1 please have Troy W's Mommy & Daddy take away his keyboard. Just because you can put together a "Lego" car doesn't make you a master mechanic. You only repeated what we said except you have a "Napoleon" complex against any1 plugging something in to a vehicle. It's the same as plugging in a light @ home. In conjunction with "kinder" nine out of ten time in my experience it usually is the oxygen sensor(s) which would be about right with the year model

SOURCE: my instrument cluster not working on 04 gmc yukon

At the odometer and P R D 3 2 1 backlights? If that's the question, it's not a fuse, it's a bad solder point on the board behind the display. If different, post a comment and I'll help some more.

If this happens when you are idle, and then you get hot air as you drive, most likely you have low coolant and it only cycles as you drive. Get approved dextrom gmc coolat and cap off your coolant it is most likely low.

You need to check the fuses in the Main power distribution box under the hood and locate the burned fuse. It is possible your alternator or Voltage Regulator was damaged by this so if all fuses are good and you find no broken fused links in the wires that Voltage regulator and Alternator would be your next stop to look for the problem. In a vehicle this new you can remove the alternator and have them both tested at Auto Zone for free.
