  1. BEFORE WORKING ON FUEL SYSTEM


    1. Before inspecting and repairing the fuel system, disconnect the cable from the negative (-) battery terminal.

      Note

      After turning the engine switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.

    2. Do not smoke or work near fire when handling the fuel system.

    3. Keep fuel away from rubber or leather parts.

  2. DISCHARGE FUEL SYSTEM PRESSURE

    CAUTION:


    • Make sure the engine coolant temperature is 60°C (140°F) or less when performing this procedure.

    • Do not disconnect any part of the fuel system until you have discharged the fuel system pressure.

    • Pressure will still remain in the fuel lines even after performing the following procedure. When disconnecting a fuel line, cover it with a piece of cloth to prevent fuel from spraying or coming out.


    1. Disconnect the fuel pump connector.

      Click here

    2. Start the engine. After the engine has stopped on its own, turn the engine switch off.

      Note

      Do not increase the engine speed or drive the vehicle while waiting for the engine to stop on its own.

    3. Crank the engine again and make sure that the engine does not start.

      Tech Tips

      DTC P0171 (System Too Lean), P1603 (Engine Stall History), P1604 (Startability Malfunction) and P1605 (Rough Idling) may be stored. Clear the DTCs before proceeding to the next step.
