It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

GMC Owners' Reviews
Bought 1997 Sonoma with 4.3 V6 and 5 speed Trans with 36000 miles on her. Since then I have 0ver 373000 miles on her as of today. She's one tough truck. Since New I have replaced 1 water pump, 1 fuel pump, 1 intake gasket. Believe it or not. I,m still on the original clutch, though She starting to chirp once in a while now. So my baby letting me know its getting to be time for replacement. I'm not afraid to travel anywhere in Her. and as I work out of town we've spent a lot of long hours on the road. Hope to find out just how long she'll keep going. And I'll definitely be buying another GM truck if its got the Vortec Engine.
no where near the f-150 ford I just sold! This truck is a rust bucket brake and transmission lines all rust! Lots of surface rust! The Ford is a credit to this rust bucket!!!
1995 GMC 1500 5.0L. 280K and still running strong. Had to replace intake gaskets twice, heater hose connectors and fuel pump. Only run 20w50 Castrol with Lucas oil stabilizer. I believe that is the secrete to a strong running 305.
Nice vehicle for hauling a family and full load, lots of room. We bought our 2003 Yukon Denali brand new. Issues we have had with this car have been the following : 1. Replace the intake gaskets, very pricey fix about $1000 2. Instrument panel lights 3. Rear suspension auto levelling system went bad, installed aftermarket overload suspension to replace the auto level system 4. Leaks from power steering pump 5. Tire wear not even due to articulating wheels 6. Front steering issues due to worn ball joints and other worn items
We did not get any of the recall items sent to us from the manufacturer, there appears to be three recalls dating back to 2003 and 2004.
This vehicle cruises real nice down the highway, gas mileage not stunning we usually get 15 mpg in town and 17 mpg on highway, I have personally done all the oil changes except for one but we always used a synthetic blend oil. I don't think the Yukon Denali XL is worth the extra money spent to get it, compared to the regular Yukon XL, we had two YUKON XL and now this YUKON DENALI XL, the price difference quite a spread. I was satisfied with our vehicle but I would have been better off with the YUKON XL two wheel drive model.
I brought my 2001 Yukon XL Denali new and still drive it today. It has 183K+ and is still in what I would call excellent condition. I'm a mechanic and have done all of my own work after my warranty expired. Although, I've had many parts failures (2 x more than my 97 Chevy C1500 PU which I also still drives), I still would rate this vehicle as "good". The largest part replaced was front differential @ 70k good thing I purchased the extended warranty package. Then there is your normal parts that wear out as well as your service parts (tires, wiper blades, brake pads, rotors and park brake shoes, air & fuel filters, fuel pump, ect.) but I did have problems with water leaking in on passenger floor, an annoying squealing noise and engine serpentine belt wearing faster than normal which took a couple of years of going back and forth to dealer (vehicle under warranty) and they found nothing. So I decided after the warranty ended to T.S. myself and after changing about 3-4 tensioners I decided to buy a high quality tensioner that corrected the belt alinement & wear problem and replacing the A/C belt & tensioner took care of the squealing noise. I just found that the moon roof clogged drains where the culprit that allowed the water drain onto the pass. floor. I would recommend this vehicle.
