        Component without harness connected

        (Fuel Injector Assembly)

        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) 12.0 Ω

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

    2. Inspect the fuel injector injection volume.

      CAUTION:

      Keep the fuel injector assembly away from sparks during the test.

        *1 Fuel Pipe (Vehicle Side)
        *a SST (Hose)
        *b SST (Hose Band)
        *c SST (Fuel Tube Connector)

        Connect SST (fuel tube connector) to SST (hose) with SST (hose band), and then connect them to the fuel pipe (vehicle side).

        SST
        09268-31014   ( 09268-41500, 95336-08070, 09268-41700 )

      2. Apply a light coat of gasoline or spindle oil to a new O-ring and it to the fuel injector assembly.

        *a SST (Hose)
        *b SST (Hose Band)
        *c SST (Adapter)
        *d SST (Clamp)
        *e Vinyl Tube

        Connect SST (adapter) and SST (hose) to the fuel injector assembly, and hold the fuel injector assembly and union with SST (clamp).

        SST
        09268-31014   ( 09268-41141, 09268-41410, 95336-08070, 09268-41700 )

    3. Install a vinyl tube to the fuel injector assembly.

      CAUTION:

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

        *a SST (Tie Band)
        *b SST (Adapter)
        *c SST (Clamp)

        Tie SST (clamp) and SST (adapter) together with SST (tie band) as shown in the illustration.

        SST
        09268-31014   ( 09268-41141, 09268-41410, 09268-41800 )

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

        *a SST (Wire)
        *b Connect

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

        SST
        09842-30080

        Note

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

        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive(+) battery terminal - Negative(-) battery terminal Per 15 seconds 47 to 57 cc (2.9 to 3.5 cu in.)
        Difference between injectors
        10 cm3 (0.6 cu in.) or less

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

    4. Check the fuel drop.


      1. In the condition above, disconnect SST (wire) from the battery and check for fuel drop from the fuel injector assembly.

        Standard fuel drop
        1 drop or less every 51 minutes

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

      2. Connect the fuel tube.
