FUEL INJECTOR REMOVAL


  1. DISCHARGE FUEL SYSTEM PRESSURE


    1. Check that the battery positive voltage is above 12 V.

    2. Discharge the fuel system pressure Click here.

    3. Disconnect the negative terminal cable from the battery.

    4. B007RPE

      Pinch and pull the No. 1 fuel hose (fuel tube connector) to disconnect it from the fuel pressure pulsation damper assembly.

      CAUTION:


      • Always read the precautions Click here before disconnecting the fuel tube connector (quick type).

      • The fuel tube may spray fuel as a result of pressure that remains in it. Do not allow fuel to be sprayed in the engine compartment.

    6. Wipe off any gasoline.

    7. Reconnect the negative terminal cable.

    8. Operate the fuel pump.


      1. Connect the intelligent tester to the DLC3.

      2. Turn the ignition switch to ON.

        Note

        Do not start the engine.

      3. Turn the intelligent tester on.

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

    9. Measure the fuel pressure.

      Standard fuel pressure
      281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi)

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

      If the pressure is lower than the specification, check the fuel hoses and connections, fuel pump, fuel filter assembly and fuel pressure regulator assembly.

    10. Start the engine.

    11. Measure the fuel pressure.

      Standard fuel pressure
      281 to 287 kPa (2.87 to 2.93 kgf/cm2, 40.8 to 41.7 psi)

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

    12. Stop the engine.

    13. Check that the fuel pressure remains as specified for 5 minutes after the engine has stopped.

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

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

    14. After checking the fuel pressure, disconnect the negative terminal cable and carefully remove SST and the fuel tube connector to prevent gasoline from spraying.

    15. Reconnect the No. 1 fuel hose (fuel tube connector) to the fuel pressure pulsation damper assembly.

  2. DISCONNECT BATTERY NEGATIVE CABLE

  3. DRAIN ENGINE COOLANT

    CAUTION:

    Do not remove the radiator reservoir cap sub-assembly while the engine and radiator are still hot. Pressurized, hot engine coolant and steam may be released and cause serious burns.

    Tech Tips

    Collect the engine coolant in a container and dispose of it according to local regulations.


    1. Loosen the radiator drain cock plug and drain the engine coolant.
