In most old cars such as a late 80's or 90's Buick Century, the fuel is gauged by a float within the tank rather than sensors attached to the tank. With this being the case, the fuel sloshes around in the tank while driving (especially when accelerating, braking, or turning) so the float gives an erratic reading.
It is to prevent the fuel from sloshing back and forth. Fuel sloshing can cause the fuel gauge to be erratic.It is to prevent the fuel from sloshing back and forth. Fuel sloshing can cause the fuel gauge to be erratic.
The fuel sending unit is sticking, or the wiring to the gauge is loose. These are the two most common causes of an erratic gauge.
Fuel Sending Unit is bad. It is a common problem in these vans!
It Seems like you may have a fuel sending unit problem
drop the gas tank and change the sending unit
Maybe bad sending unitBad/Damaged fuel sending unit. Bad/damaged wiring. Locate the wires of the fuel sending unit at the fuel tank and unplug them, see if that makes the fuel gauge to be stable (may be up all the way of down all the way, but must stop moving).If the gauge still acts erratic chances are your wiring is wring of finally (but not common) the guague itself on the dash it's damaged..
Chevy sells a tank additive that removes corrosion from the sending unit that uses resitance to gage how much fuel in tank. Check your local dealer for the additive, the gage usually shows an erratic reading due to corrosion, bad fuel quality at the pumps.
I had the same problem. What is happening is there is varnish from the fuel on the potentionmeter, and making a bad connection. I used fuel injection cleaner for a few tanks and the problem has never come back.
A gauge for measuring fuel in a tank.
Yes it sure can.
this is a problem with the gauge cluster. very common problem. you may also notice the neeedles moving very erratic at times. it is a common problem with s10/jimmy/blazers/sonoma
Reset a fuel gauge? There is not reset for a fuel gauge.
