PROCEDURE


  1. CHECK FUEL PUMP OPERATION AND INSPECT FOR FUEL LEAK


    1. Check fuel pump operation.


      1. Connect the GTS to the DLC3.

      2. Turn the ignition switch to ON.

        Note

        Do not start the engine.

      3. Turn the GTS on.

      4. Enter the following menus: Powertrain / Engine / Active Test / Activate the Circuit Relay.


        Powertrain > Engine > Active Test
        Tester Display
        Activate the Circuit Relay

      5. Check for pressure in the fuel tube sub-assembly from the fuel line. Check that sounds of fuel flowing from the fuel tank assembly can be heard. If no sounds can be heard, check the relay, fuel pump, ECM and wiring connectors.

    2. Inspect for fuel leaks.


      1. Check that there are no fuel leaks from the fuel system after doing any maintenance or repairs. If there is a fuel leak, repair or replace parts as necessary.

    3. Turn the ignition switch off.

    4. Disconnect the GTS from the DLC3.

  2. CHECK FUEL PRESSURE


    1. Discharge fuel system pressure.

    2. Measure the battery voltage.

      Standard Voltage
      11 to 14 V

    3. Disconnect the cable from the negative (-) battery terminal.

      Note

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

    5. B00430R

      Disconnect the fuel tube sub-assembly.

      Click here

    6. B00447HC03
      *1 Fuel Tube Sub-assembly (Vehicle Side)
      *a SST (Hose Band)
      *b SST (T-joint)
      *c SST (Gauge)
      *d SST (Hose Joint)
      *e SST (Hose)
      *f SST (Fuel Tube Connector)
      *g Fuel Pipe (Vehicle Side)

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

      SST
      09268-45101   ( 09268-41250, 09268-41260, 09268-41280, 09268-41500, 09268-41700, 95336-08070 )

    7. Wipe up any spilled fuel.

    8. Connect 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. Connect the GTS to the DLC3.

    10. Turn the ignition switch to ON.

      Note

      Do not start the engine.

    11. Turn the GTS on.

    12. Enter the following menus: Powertrain / Engine / Active Test / Activate the Circuit Relay.


      Powertrain > Engine > Active Test
      Tester Display
      Activate the Circuit Relay

    13. Measure the fuel pressure.

      Standard Fuel Pressure
      196 to 588 kPa (2.0 to 6.0 kgf/cm2, 28 to 85 psi)

      • If the fuel pressure is less than the standard, check the fuel hoses and their connections, fuel pump, fuel filter and fuel pressure regulator assembly.

      • If the result is not as specified, replace the fuel pressure regulator assembly.

    14. Disconnect the GTS from the DLC3.

    15. Start the engine.

    16. Measure the fuel pressure at idle.

      Standard Fuel Pressure
      196 to 588 kPa (2.0 to 6.0 kgf/cm2, 28 to 85 psi)

      Tech Tips

      Refer to Standard Idle Speed.

      Click here

    17. Stop the engine.

    18. Check that the fuel pressure remains as specified for 5 minutes.

      Standard Fuel Pressure
      147 kPa (1.5 kgf/cm2, 21 psi) or more

      If the result is not as specified, check the fuel pump, fuel pressure regulator assembly and/or fuel injector assemblies.

    19. After checking the fuel pressure, disconnect the cable from the negative (-) battery terminal and carefully remove SST to prevent fuel from spraying.

      Note

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

      Click here

    20. Connect the fuel tube sub-assembly.

      Click here

    21. Install the air cleaner cap with air cleaner hose.

      Click here

    22. Inspect for fuel leaks.

      Click here

  3. CHECK FUEL PRESSURE (for High Pressure)


    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Start and warm up the engine.

    5. Enter the following menus: Powertrain / Engine / Data List / Fuel Pressure (High).


      Powertrain > Engine > Data List
      Tester Display
      Fuel Pressure (High)

    6. Check the high pressure side fuel pressure.

      Standard Fuel Pressure
      4000 to 18000 kPa (40.8 to 183.5 kgf/cm2, 580 to 2610 psi)

      If the result is not as specified, check the fuel pump, fuel pump assembly, fuel pressure sensor and wire harnesses.

    7. Stop the engine.
