Chances are you need a new fuel level sending unit. This is located on the fuel pump assembly inside the gas tank. Replacement requires removing the gas tank from the car and replacing the whole fuel pump/sending unit assembly as a whole. These are usually available from your local auto parts store, but they are not cheap. Usually around $300

To test fuel pressure on a 1999 Pontiac Sunfire, you'll need a fuel pressure gauge. First, locate the fuel rail on the engine and find the Schrader valve, which is similar to a tire valve. Attach the gauge to the Schrader valve, then turn the ignition key to the "On" position without starting the engine to check the pressure reading. It should typically be around 41-47 psi; if it's outside this range, there may be issues with the fuel pump or fuel filter.
