- 3Turn the ignition switch ON.
- 4Listen for operational sound of the fuel pump at the filler inlet.
05U0FX-145 - 5Install the fuel filler cap.
- 6If no sound was heard, measure the voltage between the fuel pump connector wire to ground.Voltage: 12V
05U0FX-146 - 7If not correct, check the circuit opening relay and its circuits. (Refer to page F-109.)
