Fuel Injector Inspection

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

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. Remove the fuel pipe clamp.

4. Install the O-ring to the fuel injector.
   

5. Install SST and the tube to the fuel injector.

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

   *1	Lock
   *2	SST (Tie Band)

   NOTICE:

   1. As SST (tie band) does not completely prevent SST (clamp) from becoming loose, do not subject the parts to any impacts while using them.
      
   2. Before using SST (tie band), make sure that there is no deterioration, damage or cracks. If there are any abnormalities, replace SST.
      

   HINT:

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

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

8. Install a vinyl tube to the injector.
   





9. Put the injector into a graduated cylinder.

   *1	SST (Wire)

   CAUTION:

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

10. Operate the fuel pump (turn the engine switch on (IG)).
    

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

    SST

    09842-30090
    

    Standard injection volume:

    87 to 105 cm³ (5.3 to 6.4 cu in.) per 15 seconds
    

    Difference between each injector:

    18 cm³ (1.1 cu in.) or less
    

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

Check for fuel drop.

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

   Standard fuel drop:

   1 drop or less in 12 minutes
   

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