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 injector assembly.



  1. 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.

      NOTICE:
      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.

    4. Set the injector assembly in a graduated cylinder.

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

    5. Operate the fuel pump (Click here).

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

      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 injector:
      13 cc (0.8 cu.in.) or less

      NOTICE:
      Always do the switching on the auxiliary battery side.

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

  1. 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 injector.

      Standard fuel drop:
      1 drop or less every 12 minutes

      If there are excessive leaks, replace the injector assembly.
