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 fuel injector assembly injection.

      CAUTION:

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

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

        CAUTION:

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

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

      7. Operate the fuel pump.

        SST (Wire)

        *b

        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.

        Note:

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

        Standard Injection Volume

        Battery 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 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 battery and check for fuel drop from the fuel injector assembly.

        Standard Fuel Drop

        1 drop or less per 12 minutes

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