PROCEDURE


  1. CHECK FUEL PUMP OPERATION AND FOR FUEL LEAK


    1. Connect the GTS to the DLC3.

    2. Turn the engine switch on (IG).

      Note

      Do not start the engine.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.


      Powertrain > Engine and ECT > Active Test
      Tester Display
      Control the Fuel Pump / Speed

    5. Check the fuel pump operation.


      1. Check for pressure in the fuel inlet tube from the fuel line. Check that the sound of fuel flowing in the fuel tank can be heard.

        If there is no sound, check the integration relay, fuel pump, ECM and wiring connector.

    6. Inspect for fuel leaks Click here.

  2. CHECK FUEL PRESSURE


    1. Check the battery voltage Click here.

    2. Discharge the fuel system pressure Click here.

    3. 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 battery terminal. Therefore, make sure to read the disconnecting the cable from the battery terminal notice before proceeding with work Click here.

      • When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.

    4. Disconnect the hose from the clamp.

    5. B001PW7

      Disconnect the No. 1 fuel pipe sub-assembly Click here.

    6. A0009VMC01
      *1 SST (Hose)
      *2 SST (Hose Band)
      *3 SST (T-Joint)
      *4 SST (Gauge)
      *5 No. 1 Fuel Tube Sub-assembly
      *6 SST (Fuel Tube Connector)

      Install SST (pressure gauge) as shown in the illustration.

      SST
      09268-31014   ( 09268-41500, 09268-41700, 95336-08070 )
      09268-45014   ( 09268-41200, 09268-41220, 09268-41250 )

    7. Wipe off any gasoline.

    8. Reconnect the cable to the negative (-) battery terminal.

      Note

      When disconnecting the cable, some systems need to be initialized after the cable is reconnected Click here.

    9. Operate the fuel pump.


      1. Connect the GTS to the DLC3.

      2. Turn the engine switch on (IG).

        Note

        Do not start the engine.

      3. Turn the GTS on.

      4. Enter the following menus: Powertrain / Engine and ECT / Active Test / Control the Fuel Pump / Speed.

    10. Measure the fuel pressure.

      Standard fuel pressure
      321 to 327 kPa (3.27 to 3.33 kgf/cm2, 46.5 to 47.4 psi)

      If the pressure is higher than the specification, replace the fuel pressure regulator.

      If the pressure is below the specification, check the fuel hoses and connections, fuel pump, fuel filter and fuel pressure regulator.

    11. Start the engine.

    12. Measure the fuel pressure.

      Standard fuel pressure
      321 to 327 kPa (3.27 to 3.33 kgf/cm2, 46.5 to 47.4 psi)

      If the pressure is not as specified, check the fuel pump, pressure regulator and/or injectors.

    13. Stop the engine.

    14. Check that the fuel pressure remains as specified for 5 minutes after the engine has stops.

      Standard fuel pressure
      147 kPa (1.5 kgf/cm2, 21 psi) or higher

      If the pressure is not as specified, check the fuel pump, pressure regulator and/or injectors.

    15. Disconnect the cable from the negative (-) battery terminal and carefully remove SST and the fuel tube connector to prevent gasoline from spraying.

    16. Connect the No. 1 fuel pipe sub-assembly Click here.

    17. Connect the hose to the clamp.

    18. Inspect for fuel leaks Click here.
