INJECTORS INSPECTION





1. Inspect injector injection.

CAUTION: Keep injector clear of sparks during the test.





- Install the insulator to each injector.
- Install the 3 injector holders with the 6 bolts.

Torque: 7.8 N.m (80 kgf.cm, 69 in..lbf)

Fuel Inlet Hose Union Bolt:

- Remove the union bolt and 2 gaskets, and disconnect the fuel inlet hose from the fuel filter outlet.





- Connect SST (hose) to the fuel filter outlet with SST (union), the 2 gaskets and union bolt. SST 09268-41046 (90405-09015)

Torque: 29 N.m (300 kgf.cm. 22 ft.lbf)





- Disconnect the fuel return hose from the fuel return pipe.





- Connect the fuel return hose to the fuel outlet of the pressure regulator on the delivery pipe with SST (union), the 2 gaskets and union bolt. SST 09268-41046 (09268-41071)





- Connect SST (hose) to the fuel inlet of the delivery pipe with SST (union), the 2 gaskets and union bolt. SST 09268-41046 (90405-09015)
- Put the injector into the graduated cylinder.





- Using SST, connect terminals +B and FP of the DLC1.
SST 09843-18020
- Reconnect the negative (-) terminal cable to the battery.
- Turn the ignition switch ON.

NOTICE: Do not start the engine.





- Connect SST (wire) to the injector and battery for 15 seconds, and measure the injection volume with a graduated cylinder. Test each injector 2 or 3 times. SST 09842-30060

Injection volume: 111 - 141 cu.cm
(6.8 - 8.6 cu in.) per 15 sec.

Difference between each injector:
10 cu.cm (0.6 cu in.) or less

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





2. Inspect leakage.
- In the condition above, disconnect the tester probes of SST (wire) from the battery and check the fuel leakage from the injector.
SST 09842-30060

Fuel drop: One drop or less per minute

- Disconnect the negative (-) terminal cable from the battery.
- Remove the SST. SST 09268-41046 and 09843-18020
- Reconnect the fuel inlet hose to the fuel filter with 2 new gaskets and the union bolt.

Torque: 29 N.m (300 kgf.cm, 22 ft.lbf)

- Reconnect the fuel return hose to the fuel return pipe.
- Remove the 6 bolts, 3 injector holders and 6 insulators.
