FUEL INJECTOR INSPECTION

PROCEDURE


  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 fuel 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.

        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.

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

      4. Install a vinyl tube onto the fuel injector assembly.

        CAUTION:

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

        SST

        (Wire)
        *a Connect

        Connect SST (wire) to the fuel injector assembly and the auxiliary 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 do the switching on the auxiliary battery side.

        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 fuel injector assembly
        13 cc (0.8 cu. in.) or less

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

        Standard fuel drop
        1 drop or less every 25 minutes

        If there are excessive leaks, replace the fuel injector assembly.
