Fuel Injector -- Inspection



1. INSPECT FUEL INJECTOR ASSEMBLY

  1. Measure the resistance between the terminals.

    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 INJECTION VOLUME AND LEAKAGE


  1. Check the injection volume.

    CAUTION:
    This test involves high-pressure fuel and electricity, therefore, safety precautions should be taken. Perform this test in a safe area and avoid any sparks and flames. Do not smoke.

    1. Discharge the fuel system pressure (HILUX_TGN26 RM000000YL401NX.html).

    2. Remove the fuel hose from the fuel pressure pulsation damper (HILUX_TGN26 RM000000UK105EX.html).

    3. Remove the fuel hose from the fuel filter (HILUX_TGN26 RM000004JUV007X.html).

    4. Disconnect the fuel pressure regulator (HILUX_TGN26 RM000000YLE01BX.html).

      NOTICE:
      Do not disconnect the No. 2 fuel hose from the fuel pressure regulator.

    10. Put the injector into a graduated cylinder.

      CAUTION:
      Install a suitable vinyl tube onto the injector to contain the gasoline spray.

    11. Operate the fuel pump.

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

      SST
      09842-30080
      Standard injection volume:
      95 to 115 cm3 (5.8 to 7.0 cu. in.) in 5 seconds
      Difference between each injector:

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

  1. Check the fuel leakage.

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

      Fuel leakage:
      1 drop or less per 12 minutes
