FUEL INJECTOR INSPECTION

PROCEDURE


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. Check the resistance.


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

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

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

    2. Check the operation.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near an open flame.

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

        CAUTION:

        Install a suitable vinyl tube onto the fuel injector assembly to prevent fuel from spraying.

      6. Operate the fuel pump Click here.

        *1 SST (Wire)
        *a Connect

        Connect SST (wire) to the fuel injector assembly and the battery for 15 seconds, and measure the injection volume with a graduated cylinder. Test each fuel injector assembly 2 or 3 times.

        SST
        09842-30080
        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive (+) terminal - Ground terminal Per 15 seconds 76 to 91 cc (4.6 to 5.6 cu. in.)
        Difference between each fuel injector assembly
        15 cc (0.9 cu. in.) or less

        Note

        Always switch the voltage on and off at the battery side, not the fuel injector assembly side.

        If the injection volume is not as specified, replace the fuel injector assembly.

    3. Check for leaks.


      1. Disconnect the tester probes of SST (wire) from the battery and check for fuel leaks from the fuel injector assembly.

        Standard fuel drop
        1 drop or less every 35 minutes
