My 2003 Buick LeSabre started doing this one day. Only happens after there is less than half-a-tank of gas left. I’m just going to live with it for now.

Your fuel sensor has gone bad. Replace it by accessing the fule pump
through the truck.
@1stsmosh no you remove it via the trunk, the pump assembly is SPRING
LOADED and gets TALLER AND SHORTER you must COMPRESS IT by hand (MAKE IT
SHORTER) and it comes right out. If you drop the tank you are really doing
it only cause YOU want to not cause its the way to make this repair
Mines does the exact same thing. Only when there gas pass half a tank I
wants to act right. Anything below that will leave me guessing.
@skyfirefighter1 fuel sender attached to fuel pump bad from running tank
half full all the time, corrodes sender, keep yer tank full wont happen
my 2 cents… 2001 OLDS AURORA. ONLINE BLOG FOR GM HAD PART NUMBER..$28
DEALER PART…ONLY NEED TO REPLACE THE CONTACTS THAT WERE MENTIONED ABOVE.
IF IT IS ACCESSIBLE THRU TRUNK……GM TYPICAL..IT’S NOT TOO BAD…NO NEED
TO DROP TANK…
Got a 2002 lesabre, same issue, it’s annoying but I’ve learned to just fill
up about every 300miles.
Well then you have a Buick with extended trunk space…when it was tried
here, there was not enough room vertically to take out the assembly.
@SMAN873 yes a new fuel pump for a buick (HUNDREDS OF DOLLARS) comes with a
new sender (MANY LESS DOLLARS), but if the pump is working (car starts u
can drive it) i would just replace the sender on the pump
How do you fix it mine does that bug just now its not marking at all now it
goes fro. E to quarter when im driving when im parked it goes to E bellow
please help.
@ericrichard7 I just watched my miles, I think I used to let it go to 350
and then fill up.
@1stsmosh I don’t think it’s something I would have tried tackling myself.
I lived with it for about a year. The Buick was totaled in an accident a
few months ago so it’s no longer a problem for me!
@1stsmosh ok conspiracy theory, the real fact is when gas is cheap people
keep their cars fuller, when its expensive, they ride on fumes all the
time, this exposes the sender to air more often than not (SITS OVERNIGHT)
and that corrodes the sender. This is happening more and more the past 5
years, as it just happens fuel has been expensive and the economy tight,
hope i didnt explode your mind with facts, there is no grassy knoll here
We had a 2000 Buick lesabre that kept going. We had to scrap it today
because the whole front end was messed up the intake was cracked and a
whole lot of other stuff but ours did that too and we fixed it by replacing
the fuel pump
its like a boner
2004 here, mine dropped below “E” and won’t come back up.
I have a 2000 and i had the same thing happen only it would either say
empty or full lol i just used the trip meter
@sc00b3rt Same exact thing! I’ve learned to ignore it and watch my miles.
same problem with my buick 2002 century, besides that my PRND / odometer
reading light is busted, and i have to solder the 4 resistors.
The problem is a brass metal resistor which wears out after 8 to 11 years.
So we have the technology to put humans into space but can’t have a method
for a fuel gage to last 25 years on a Buick. GMC did this on purpose to get
the vehicles back in for repair to support the dealerships.
Many of this same problem….and even those who say they had it
repaired….no one has pointed toward the cause. I tried replacing the Fuel
Pump with a used one and it did not fix it….maybe that one was bad too.
i have a 1998 buick LeSabre that fuel gauge is messed up
btw its the sedan if it matters
Got the same issues with our 2004 SUV Buick rendezvous,just living with the
it for now…keeping a jerry can on hand for when i have to march to the
petro station.
My car would wobble when you drove it and all the rims were bent to the
point of where nobody knew how they held air!
there shud be a recall on 2000-12 Buick Lesabre’s gas gauge problems!
@1stsmosh On the 2000 to 2005 lesabre there is an access panel in the trunk
to get to the sending unit. Must have been a common problem for that to be
added
I have the same car and the same problem, where is the sending unit pump
assembly located?
1996 buick regal gs. Same problem. goes up when accelerating, down when
braking/turning. only moves 1/4 tank though and eventually settles. whats
the problem? its very annoying.
2000 LeSabre, same thing happening to mine. Goes all over the place. If its
under 1/2 a tank its possessed. Just living with it, watching my miles as a
gauge.
Yes that has been tried, but there is not enough vertical space to lift the
assembly up out of the hole. You still have to take down parts of the
exhaust system, remove all the fuel for safety, cap off the lines, and drop
down the tank.
