Question about 1997 Buick LeSabre

1 Answer

Fuel gauge always registers "full"

I just purchased a 97 buick lesabre for my son's 18th birthday. The car appears to be in excellent condition (mechanic owned) with 170K miles. When we brought the car home, we were pleasantly surprised to see that the gas tank was "full". For some reason we decided to go to the gas station and see just how "full" it was, we put in a $25 gas card and the tank took the entire thing, (about 7.5 gal). It's hard to tell how much more it would have taken, since my son didn't want to add any more money to it.

I'm glad we took it to the station or he may have gotten on the highway to go home that night and ran out of gas, thinking the tank was full! Does anyone know if this is a difficult/costly problem to fix? I hate for him to have to depend on the odometer/avg. mpg to determine if he has enough gas to get him from one place to the next. Thanks! Dayna

This could be as simple as a broken wire in the sending unit harness or it could inolve having to remove the tank to get to the pump to replace the float. best way is to check to make sure that there is power going to the sending unit in the tank. if there is and i suspect that there is because the fuel pump works so either your float is stuck or the guage itself is bad these are your options to check out... please rate this........thanks

What may be wrong with fuel gauge not registering properly

Could be the sending unit in the gas tank or the gauge on the dash.
Until you get it fixed, you can use your odometer to remember to fuel up. Just stay under 200 miles per full tank of gas.

The fuel needle is broke, I bought the 97 Lesabre two days ago on a full tank of many miles can I get out of a full tank

The fuel gauge needle isn't the problem the fuel gauge sending unit inside the gas tank is the cause of this problem, it is not sending a signal to the gauge
As far as how many miles you can go that would be around 300 mixed city and highway most likely.
