2002 Yukon XL 2500 6.0L





Full tank of fuel and the fuel gauge just started reading empty with the low fuel light on as well.


When I turn the truck on and off the gauge moves to full then goes back to empty.


Has this been recalled or do I really have to pay my dealer 400 bucks (one months truck payment) to fix the gauge?


The truck has 65000 miles on it!

Sounds like you have a bad sending unit in tank. They are not too bad to change if tank is empty and bolts are in good shape. I have heard of some pulling bed to gain access to sending unit but I consider that a bit extreme. Edited by: snoman

Is there a way to "reset" the sensor with a tech 2?

It is a float and potentiometer device and the wiper or the resistance strip gets damaged (bad fuel with water in it will do it as well as normal wear but they "seem" to last longer if tanks are keep mostly full) and there is no reset. It is R&R item when it fails sorry. Either Shell or BP (I forget which one) had some bad gas a few months ago and it was wiping out float sensors in GM gas trucks left and right. They were paying for repairs back then but not sure if it applies to you.

Pullin the bed if you gotta hoist is much faster an you don't have to worry about how much fuel is in the tank. 4 bolts and the wire connections plus 3 screws that hold the gas cap nozzle in place

Pulling the bed on a Yukon XL?http://www.dieselplace.com/forum/smileys/Wacko.gif


I don't think that's gonna happen!


He's going to need about 8 gas cans to drain the tank (which he mentions is full).http://www.dieselplace.com/forum/smileys/Pinch.gif


Either that or just one gas can, to get it home after it runs out of gas.


The in-tank fuel pump on my '91 C1500 failed 3 miles after I left the gas station. 34 gallons of unleaded is a pain to deal with, and way more than I can lift.

You can siphon or pump the fuel out too. On a truck that new, dropping tank should not be a problem , it is a the old trucks that are rusted that can be "fun"Edited by: snoman

I have a 2001 Silverado that has had this problem since about 40K. It seems to do it mostly when the tank is completely full, but after a few gallons have been used works well so it's not really worth the hassle to drop the tank to fix it. Truck has over 85K on it now.

Ypu have a bad spot of the "wiper" contact area on the float resistance strip. Hopefully it will not get worse for you.

Well its going in tomorrow for a $400.00 bill to replace something.

The float assemblies are usually around 50 to 75 bucks themselves so the rest is basically labor for what it is worth.

Did one recently - not a hard job. Ran the vehicle almost out of gas and disconnected the fuel filter. Turned the key on and used the fuel pump to pump the rest of the fuel into a can. Dropped the tank in no time. Only thing I had to fight with was the darn fuel line quick connects that GM uses - UGHHH!http://www.dieselplace.com/forum/smileys/Disapprove.gif

Well the update is "both sending units are bad...one for each tank"


First my question is does my yukon xl have 2 fuel tanks?


Second is how does both sending units go bad at the same time?

Problay two chambers in one tank and on good "bad" batch of fuel with water in it can take then out.

AhHA...


I did read an article in my dealers lobby about bad fuel causing problems with these units....gotta go read the article again...I think it said somethihng about the fuel company footing the bill to repair the units...


Thanks alot for all the replies!

Bottom line was 1/3 the price....The dealer hooked me up!


Yes the Yukon XL does have 2 tanks.(one on each side of the axle)
