FUEL INJECTOR (for Port Injection) INSPECTION


  1. INSPECT FUEL INJECTOR ASSEMBLY


    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 resistance is not as specified, replace the fuel injector assembly.

    2. Inspect the injection volume.

      CAUTION:

      This test involves high-pressure fuel and electricity. Take all precautions regarding safe handling of both the fuel and the electricity. Perform this test in a safe area, and avoid any sparks or flames. Do not smoke.

      *1 Fuel Pipe
      *2 SST (Fuel Tube Connector)
      *3 SST (Hose)
      *4 SST (Hose Band)

      Connect SST to the fuel pipe (the vehicle side).

      SST
      09268-31014   ( 09268-41500, 09268-41700, 95336-08070 )
    5. A01FSAFE01

      Install the O-ring to the fuel injector.

    6. Install SST and a tube to the fuel injector.

      SST
      09268-31014   ( 09268-41600, 09268-41300, 09268-41700, 95336-08070 )

      *1 O-ring
      *2 SST (Adapter)
      *3 SST (Hose Band)
      *4 SST (Clamp)
      *5 Vinyl Tube
    7. A01FV4PE01

      *1 Lock
      *2 SST (Tie Band)

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

      SST
      09268-31014   ( 09268-41800 )

      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.

      Tech Tips

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

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

    9. Install a vinyl tube to the injector.

      Note

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

      *1 SST (Wire)

      Put the injector into a graduated cylinder.

      SST
      09842-30090

      CAUTION:

      Install a strong rubber tube onto the injector to prevent gasoline from splashing.

    11. Operate the fuel pump (turn the power switch on (IG)).

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

      Standard injection volume
      53 to 63 cc (3.2 to 3.8 cu.in.) per 15 seconds
      Difference between each injector
      10 cc (0.6 cu.in.) or less

      Note


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

      • Always turn the voltage on and off on the battery side, not the fuel pump side.

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

    13. Check for leakage.


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

        Standard fuel drop
        1 drop or less in 27 minutes

        If there is excessive leakage, replace the injector.
