FUEL INJECTOR INSPECTION

PROCEDURE


  1. INSPECT FUEL INJECTOR ASSEMBLY


    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. Inspect the injector injection volume.

      CAUTION:

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

      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 contain any fuel spray.

        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.

        Note

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

        Standard Injection Volume
        Tester Connection Condition Specified Condition
        Positive terminal - Ground terminal Per 15 seconds 87 to 105 cc (5.3 to 6.4 cu. in.)
        Difference between each fuel injector assembly
        18 cc (1.1 cu. in.) or less

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

    3. Check for fuel drop.


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

        Standard fuel drop
        1 drop or less per 20 minutes

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