FUEL INJECTOR INSPECTION

PROCEDURE


  1. INSPECT FUEL INJECTOR ASSEMBLY


    1. B003ZLJC02
      *a

      Component without harness connected

      (Fuel Injector Assembly)

      Check the resistance.


      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. Check the operation.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near an open flame.


      1. B003ZB0C19
        *a SST (Hose)
        *b SST (Hose Band)
        *c SST (Fuel Tube Connector)
        *d Fuel Pipe (Vehicle Side)

        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, 09268-41700, 95336-08070 )

      2. Apply a light coat of gasoline to a new O-ring. Then install the O-ring onto the fuel injector assembly.

      3. B003ZA6C04
        *1 O-ring
        *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, 09268-41700, 95336-08070 )

      4. 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.

      5. B003YY7C04
        *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 )

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

      7. Operate the fuel pump.

      8. B003Z4KC20
        *a SST (Wire)
        *b Connect

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

        SST
        09842-30080
        Standard Injection Volume
        Battery Connection Condition Specified Condition
        Positive (+) battery terminal - Negative (-) battery terminal Per 15 seconds 84 to 101 cc (5.1 to 6.2 cu.in.)
        Difference between Each Fuel Injector Assembly
        17 cc (1.0 cu.in.) or less

        Note

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

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

    3. Check for leaks.


      1. Disconnect SST (wire) from the battery and check for fuel leaks from the fuel injector assembly.

        Standard Fuel Drop
        1 drop or less every 35 minutes

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