INSPECTIONInspect Injector Injection
CAUTION: Keep Injector clear of sparks during the test.
1. Disconnect the fuel inlet hose from the fuel tube.
2. Connect hose to the fuel inlet tube with union. Tighten the flare nut on the fuel tube. (SST 09268-41045)
Torque: 30 Nm (22 ft lb)
3. Loosen the lock nut, and remove the pressure regulator from the right hand delivery pipe. Remove the 0-ring from the pressure regulator.
4. Install a new 0-ring to the fuel inlet of the pressure regulator.
5. Connect hose to the pressure regulator with union. Tighten the lock nut on the pressure regulator. (SST 09268-41045)
Torque: 29 Nm (22 ft lb)
6. Connect the fuel return hose to the fuel outlet of the pressure regulator with union, 2 new gaskets and union bolt. (SST 09268-41045)
Injector Hookup:
7. Install the grommet and a new 0-ring to the injector.
8. Connect hose to the injector with union, and hold the injector and union with clamp. (SST 09268-41045)
9. Put the injector into the graduated cylinder. Install a suitable vinyl hose onto the injector to prevent gasoline from splashing out.
10. Using jumper, connect terminals +B and FP of the data link connector 1.
11. Reconnect negative (-) terminal cable to the battery.
12. Turn the ignition switch ON. DO NOT start the engine.
13. Connect wire to the injector and battery for 15 secounds and measure the injection volume with a graduated cylinder. Test each injector 2 or 3 times. (SST 09842-30070)
Volume: 55 - 70 cm3 (3.4 - 4.3 Cu in) per 15 seconds
Difference between each injector: 10 cm3 (0.6 Cu in) or less
If the injection volume is not as specified, replace the injector.
Inspect Fuel Leakage
1. In the condition above, disconnect the tester probes of wire from the battery and check the fuel leakage from the injector. (SST 09842-30070)
Fuel drop: One drop or less per minute
2. Disconnect the battery negative (-) cable.
3. Remove the jumper.
4. Reconnect the fuel inlet hose to the fuel tube.
Torque: 30 Nm (22 ft lb)
HINT: Use a torque wrench with a fulcrum length of 30 cm (11.81 in)
5. Reinstall the fuel pressure regulator to the right hand delivery pipe.
- Fully loosen the lock nut on the pressure regulator.
- Apply a light coat of gasoline to a new 0-ring, and install it to the pressure regulator.
- Completely insert the pressure regulator into the delivery pipe by hand.
- Turn the pressure regulator counterclockwise until the vacuum sensing port faces in the direclion indicated in the illustration.
