Question about Chevrolet Uplander LS

1 Answer

2006 Uplander- filled up, got in gas gauge said only 3/4 full, thought oh well, operator issues. Then I started out driving, suddenly my cd player made a electrial surge type of sound and stopped working completely. Radio still worked though. Arrived at destination, indicator came on warning low fuel, low fuel.(Distance of 7 miles from location of fill) Turned off the van. Came back to van, started up and gas gauge had risen up to 1/2 tank and screen on radio/cd player totally blank and nothing working. Drove 5 miles back home, pulled into drive way. Shut off van. Noted that the fuel tank all the sudden showed full tank and decided to try to get my cd out of player and sure enough, was able to remove cd and the radio worked. Problem is going off to vacation from PA to Maine on this coming Sunday, wondering if we will make it or if something major will happen to electrical system.

Your fuel sending unit is on the fritz.
The noise you heard was the LOW FUEL indicator buzzer going throught the radio (it does not have a separate speaker in your vehicle - the chimes play through the radio). It could be anything from the sending unit itself - to a pinched/damaged wire or ground.
While it won't prevent you from making your trip - be aware that your fuel capacity will not report correctly - so keep good records, and fill up after 3/4 tank is gone.

The BCM (Body Control Module) is the common denominator here and controls the 2 items that are gifing you problems - so a problem in the sending unit could be what is making your radio act up - since it is getting the bad/partial signal (and maybe even a ground loop - or power to ground situation) from the sending unit to give an audible chime.

Have a good trip - and thanks for using FixYa!!

My 2006 Chevy Uplander seems to slip when it shifts, or has an extremely hard shift.


Check the fluid level, if possible and fill until full when at normal operating temperature.

If this doesn't solve the problem, maybe consider a flush and fill of the transmission fluid, with the understanding that if this doesn't solve the problem, a rebuild may be required at that point.

Typical price for a flush and fill will be about $100.

Good luck on this repair.

Stop at gas station after driving 250 miles in my 2000 s10 extreme and pump shuts off like tank is full after 3 gallons of gas go in...should take 11 or so gallons. Also gas gauge stays on full and will...


sounds like you have a restriction in the fuel inlet pipe,( maybe air locking) also your tank sender unit neads replacing to fix you gauge fault, or it maybe that it has something that is not alowingf it to move freely inside the tank, have a good look inside when low on fuel. through the hole where the sender is fitted.

Check engine light comes on after refueling the vhicle. gauge doesn't read full, then it will. light goes out after a day or two.


Also, be sure to not over-fill the gas tank. When filling the tank, when it sounds full (you can hear gas gush up the filler neck) and when the filler clicks off the first time...don't be tempted to keep clicking more gas into the tank because over-filling can cause a variety of problems (including setting the light) and can eventually saturate/ruin the fuel vapor canisters.

2006 envoy gas gage


your gas gauge sensor is most likley the problem on alot of new cars they measure your fuel off an average of were your float is at. like if your not moving it stays in one spot but as you move the float moves and reads the lowest amout that it is averaging and if your float keeps reading low your going to read that you have alot less gas than you really do. have you tried filling the tank all the way and see what it does? if it stays at full until you use some gas and your float starts moving your gas gauge will probley go down in that case its the fuel sensor if this dont help let me know and ill c what i can find out for you
