Buick LeSabre Erratic Fuel Gauge Operation

(225 reports)

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.

Fel- + fuel sensor. Can it be removed from the trunk access? -
Fuel gauge has false readings when under half of tank...dealer said it was fuel level sensor..Approx $ 500.00 to repair.. have been using trip meter, at 200 miles I fill up....Does any one know if this module can be replaced by removing inside of trunk panel???? -
Gas gauge needle reads full all the time -
guage becomes very eratic when it drops below the 3/4 mark -
fuel gauge inop shows full at all times.. -
Replaced fuel pump and the problem still there. -
Gas gauge stopped reading correctly. Diagnosed by dealer as the gas tank module. Buick wants $700 to install new one, parts and labor. What a ripoff. We keep track of mileage but my old Toyotas never had a failure like this in only 10 years! -
it doesn't register properly. I just keep track of the mileage. -
Erratic Fuel Gauge Operation due to faulty plastic on the part. Opted to NOT replace, just watch the mileage on the car and fill tank every 100 miles of in town driving. -
mechanic said it would be $500 to fix so i didn't. it became erratic at less than half a tank. -
fuel sensor doesn't register the correct level of gas left. false readings -
my gas gauge would only work when it reached the half way mark. anytime before that it read full the whole time. its not a really a big deal though because atleast i wont ever run out of gas haha. -
When the fuel level gets down to half a tank or less the fuel gauge readings become erratic, have not fixed it. -
fuel level gauge doesn't accurately reflect fuel level. Often indicates full tank, when it may be near empty. -
my fuel gauge will read 1/4 tank, the after I turn a corner it will go up to full and stay there. I know there is only a 1/4 tank. I was told to replace the fuel sensor. . -
fuel gauge goes from 1/4 to 3/4 when tank is under half. -
When near empty the fuel gage shows a half tank and gauge goes back and forth from near empty to half full. -
I now have 132,000 miles on the car and have learned to live with this problem. When I first get into the car I turn the key partially so the gauges read . This brings up an accurate reading of the gas gauge. Only after I start to drive does the gauge move to the full position and stay there.Knowing my average fuel consumption I can calculate how far I can go and still have gas. I never let the tank go below one quarter full. If the gauge stops working completley, I will have it repaired. -
car wont start, low fuel range light on, fuel in car -
