Maybe the rest of the gas in the tank is unusable and has clogged the fuel filter inside the tank or even the injectors are clogged. Disconnect the fuel line from the fuel rail of the throttle body, direct it into a jar and switch on the ignition. If there is not a short shot of fuel coming, the culprit should be traced inside the gas tank (fuel pump, filter, regulator) and if there is fuel inspect the injectors including the electrical pulsing.
