1. INSPECT FUEL INJECTOR ASSEMBLY


  1. Check the resistance.



      A116182
    1. Measure the resistance according to the value(s) in the table below.

      Standard Resistance:
      Tester Connection
      Condition
      Standard Condition
      1 - 2
      20°C (68°F)
      11.6 to 12.4 Ω

      HINT:
      If the result is not as specified, replace the fuel injector assembly.



  1. Check the operation.

    NOTICE:
    Perform the inspection in a well-ventilated area. Do not perform the inspection near any flames.

      O-ring

      NOTICE:
      SST (connector) seals the fuel tube connector and pipe with an O-ring. Ensure that there is no damage or foreign matter on the contact surface. Install the O-ring onto the fuel injector.

    5. Set the fuel injector assembly in a graduated cylinder.

      NOTICE:
      Install a suitable vinyl tube onto the injector assembly to prevent fuel splashes.

    6. Operate the fuel pump (Click here).

    8. Connect SST (EFI inspection wire H) to the battery for 60 seconds, and then measure the injection volume with the graduated cylinder. Repeat 2 or 3 times and calculate the average.

      SST
      09842-30080  

      Injection Volume:
      Tester Connection
      Condition
      Specified Condition
      Positive terminal - Ground terminal
      1 minute
      193 to 205 cm3 (11.8 to 12.5 cu in.)

      Difference between injectors:
      12 cm3 (0.7 cu in.) or less

      CAUTION:
      Always do the switching (voltage on/off) at the battery terminal.

      HINT:
      If the injection volume is not as specified, replace the injector.



  1. Check for leaks.



      A116184
    1. In the condition above, disconnect SST (EFI inspection wire H) from the battery and check the fuel leakage from the injector.

      Fuel drop:
      1 drop or less every 12 minutes

    2. Connect the fuel tube.

      HINT:
      Refer to "Precaution" for the fuel tube connection procedure (Click here).

    3. Install the fuel pipe clamp.
