FUEL INJECTOR INSPECTION

PROCEDURE

  1. INSPECT FUEL INJECTOR ASSEMBLY

    1. 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 injector assembly.

    2. Check the injection volume.

      CAUTION:

      • Perform the inspection in a well-ventilated area.

      • Do not perform the inspection near any naked flames.

        Install the O-ring to the fuel injector assembly.

      3. Connect SST (adapter and hose) to the fuel injector assembly, and hold the fuel injector assembly and union with SST (hose band).

        Lock

        Pass SST (tie band) through the loop on the handle of SST (clamp) to secure SST (clamp) to SST (adapter).

        Note:

        • As SST (tie band) does not completely prevent SST (clamp) from becoming loose, do not subject the parts to any impacts while using them.

        • Before using SST (tie band), make sure that there is no deterioration, damage or cracks, If there are any abnormalities, replace SST.

        Tip:

        When removing SST (tie band), disengage the lock.

      5. Check that SST (clamp) and SST (adapter) cannot be easily separated.

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

        Note:

        Install a suitable vinyl tube to the fuel injector assembly to prevent gasoline from splashing out.

      7. Put the injector into a graduated cylinder.

      8. Operate the fuel pump.

        Connect

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

        09842-30080

        Standard injection volume

        60 to 73 cc (3.7 to 4.5 cu. in.) per 15 seconds

        Difference between each injector

        13 cc (0.8 cu. in.) or less

        Note:

        • Make sure that SST (EFI inspection wire H) is securely connected.

        • Always do the switching at the battery side.

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

    3. Inspect for fuel leaks.

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

        Standard

        1 drop or less every 12 minutes
