My 2004 Yukon XL fuel gage was not correct all the time.
Right after my warrantee expired, fuel gage was not showing correct.
I have to guess how much gas I have with mileage.
I went to dealer for a special warrantee to fix the gage panel cluster, but still same.
Any help?
Problem may be with the level sending unit, which is part of the fuel pump assembly in the fuel tank. You can check this with a good code reader that will give you live data from this unit and compare it with what the gauge is saying. If they don't match, you can try a good quality fuel system cleaner to see if that solves the problem. If they do match, then the problem is probably still in your instrument panel (IP) or engine computer.

There are 2 fuse panels in the Denali.
One is a panel on the drivers side, its on the dash but facing the door.
The ohter is under the dash and above the pedals, this one is much tougher to access.
Your Owner's Manual should tell you where the fuses are that you need to access.

You can get the codes checked and see if you have a level sensor code.The level sensors are known to go bad on these vehicles.Sometimes when you rock the vehicle it will start to work properly.What happens is the fingers on the level sensor wear out and it works erratically.You can get the level sensor separately from the fuel sending unit.Hope this helps.Good luck.

When I fill-up, gage show 3/4 full.
And after that, gage show up and down.
Today showing run out of gas, later today 1/2 full.
gage are not correct but never show more than I have.
what did they fix or replace ? and does the gauge read enpty or full ? all the time ?
Sometimes you can use resisters to check the fuel gage. You take wire connector loose from sending unit, the proper two wires, you use a resistor between those wires, one resistor for empty and another for full, turn key just till dash lites come on, note the gage. If the gage reacts properly to each resistor, the problem is the sending unit in the gas tank. Just my opinion.
