2007 2500 Suburban 4wd Fuel System Issues...

[JLeosnow]

Has anyone else experienced issues with the vehicle prematurely shutting down/acting like it is out of fuel when the gauge on the dash clearly shows a 1/4 tank of fuel left? It has happened twice on our trip out west and luckily we carry fuel in our trailer. The weird thing is is that when I pour the 6 gallons in from the container it brings the gauge up to a 1/2 tank and the truck starts right up again... Very uneasy feeling not being able to use much more than a 1/2 of our tank when only getting 5.9 miles to the gallon towing into the strong Dakota winds in the middle of the night!

 

Any help/others experiences would be much appreciated!

I have the opposite problem. When mine says empty I can only squeeze in about 34 gallons.

you sure your gauges are working properly? something doesnt sound right

My DIC shows gallons used and it is usually very close to what I put in when I finally fill up.

 

The gauge will have been on "E" and the low fuel light on for a whole day of driving and I'll still only squeeze in 34 or 35 gallons, which will be very close to what the DIC says I have used.

 

I reset it at every fill-up and it will say I've used +/- 1/2 gallon of what I actually put in so I know that's close.

Probably a problem with the fuel level sensor.
