FUEL INJECTOR INSPECTION

  1. INSPECT FUEL INJECTOR ASSEMBLY

    1. Check the resistance.

      A011TN7

      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.

    2. Check the operation.

      CAUTION:

      Perform the inspection in a well-ventilated area.

      Do not perform the inspection near a naked flame.

      1. Connect SST (fuel tube connector) to SST (hose) with SST (hose band), and then connect them to the fuel pipe (vehicle side).

      2. Install a new O-ring onto the fuel injector assembly.

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

      4. Tie the clamp and adapter together with a tie band as shown in the illustration.

      5. Set the injector assembly in a graduated cylinder.

        CAUTION:

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

      6. Operate the fuel pump Click here.

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

        Difference between each injector
        15 cc (0.9 cu.in.) or less

        Note

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

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

    3. Check for leaks.

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