FUEL INJECTOR INSPECTION


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. Check the resistance.


      1. Using an ohmmeter, 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 injector assembly.

    2. Check the operation.

      Inspect the injector injection volume.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near an open flame.

        SST

        (Fuel Tube Connector)

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

        SST
        09268-31013   ( 09268-41500, 90467-13001, 95336-08070 )

        Note

        Ensure that the SST connector O-rings are not damaged and are free of foreign matter as they are used to seal the connections between the fuel tube connector and pipe.

        Install a new O-ring onto the fuel injector assembly.

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

        SST
        09268-31013   ( 09268-41110, 09268-41300, 90467-13001, 95336-08070 )

      4. Set the injector assembly in a graduated cylinder.

        CAUTION:

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

      5. Operate the fuel pump Click here.

        SST

        (Wire)
        *a Connect

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

        SST
        09842-30080
        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive terminal - Ground terminal Per 15 seconds 60 to 73 cc (3.7 to 4.5 cu.in.)
        Difference between each injector
        13 cc (0.8 cu.in.) or less

        Note

        Always do the switching on the auxiliary battery side.

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

    3. Inspect for leaks.


      1. In the condition above, disconnect the test probes of SST (wire) from the auxiliary battery and check for fuel leaks from the injector.

        Standard fuel drop
        1 drop or less every 12 minutes

        If there are excessive leaks, replace the injector assembly.
