If you are having this problem with < 1/2 tank of gas, then likely your pre-pump is not running or the hose to the pre-pump is torn (these are both in the tank, accesible from the sending unit opening).

If this is a problem, other simptoms would also have been difficulty to start with a not-full tank.

In this case, it is the job of the main pump (under the rear seat area) to pull all the gas out of the tank. This destroys the main pump and overheats the fuel pump relay (pack of 2 in 1).

While diagnosing the fuel delivery system ( always a problem on these older cars), you would want to replace the fpr (fuel pressure regulator ) under the hood attached to the fuel rail at the injectors. This though would not cause a no-start scenario.

Good luck.
