Because it is broken
The sender unit( wire harness is bad) take off the old and put on new. good luck pulling the fuel tank.
Inside the fuel tank.
Fuel pump failure is one possibility.
Does not have one.
The fuel pressure of a 1999 Oldsmobile 3.8 liter V6 is 35 psi. A fuel pressure gauge is needed to measure the fuel pressure.
no you have to remove fuel tank
Most likely either a bad float in the fuel tank or defective gauge
most fuel gauge problems are due to a bad fuel sender unit which is mounted inside the fuel tank. have wires and gauge tested for signal before dropping fuel tank
It's attached to the fuel pump sending unit, inside the fuel tank.
are you sure you reconnected the wire to the gauge when you did the fuel pump? also the gauge requires a good ground to the tank. its possible you don't have a good connection. just some thoughts.
where is the fuel pump relay located on 1995 oldsmobile cutlass supreme 3.1L
If your fuel gauge is out of wack, go to the local parts store and orfer some fuel gauge wack. Pour it directly into the gauge until it is full of wack..........
you should not be driving
