Fuel Injector (For Port Injection)

INSPECTION

1. INSPECT FUEL INJECTOR ASSEMBLY

SST 09268-31012 (09268-41500, 90467-13001, 95336-08070, 09268-41300, 09268-41600), 09842-30090







a. Measure the resistance of the injector.

If the resistance is not as specified, replace the injector.

b. 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.




c. Remove the fuel pipe clamp.




d. Disconnect the fuel tube.




e. Connect SST to the fuel pipe (the vehicle side).
f. Install the O-ring to the fuel injector.




g. Install SST and tube to the fuel injector.

SST 09268-31012 (09268-41500, 90467-13001, 95336-08070, 09268-41300, 09268-41600)




h. Put the injector into a graduated cylinder.

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

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

j. 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: 76 to 91 cu.cm (4.6 to 5.6 cu.in) per 15 seconds

Difference between each injector: 15 cu.cm (1.0 cu.in) or less

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




k. 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 25 minutes
