2. INSPECT INJECTOR OPERATION Check the each injectors for operation sound. With the engine running or cranking, use a sound scope to check that there is normal operating noise in proportion to the engine speed. If you have no sound scope, you can check it by feeling the injector operating vibration with your finger. If no sound or unusual sound is heard, check the wiring connector, injector or injection signal from the ECM.

1. INSPECT INJECTOR INJECTION CAUTION: Keep injector clear of sparks during the test. Disconnect the fuel pipe clamp from the fuel tube connector. Disconnect the fuel inlet tube (fuel tube connector) from the fuel pipe. CAUTION: Disconnect the fuel tube connector (quick type) observing the precaution (see «SFI SYSTEM»(ref-239091-S33576169842006072600000) ). As there is retained pressure in the fuel line, prevent it from splashing inside the engine compartment. Purchase a new fuel tube. Remove the fuel tube connector from its pipe. Fuel tube: Part No. 23901-22110 Connect SST (hose) and fuel tube connector to the fuel pipe. SST 09268-41047 CAUTION: Disconnect the fuel tube connector (quick type) observing the precautions (see «SFI SYSTEM»(ref-239091-S33576169842006072600000) ). Install the grommet and O-ring to the injector. Connect SST (union and hose) to the injector. SST 09268-41047 (09268-41110, 09268-41300) Put the injector into a graduated cylinder. CAUTION: Install a suitable vinyl hose onto the injector to prevent gasoline from splashing out. Connect the hand-held tester to the DLC3. Connect the hand-held tester to the DLC3. Connect the battery negative (-) terminal cable to the battery. Turn the ignition switch ON and push the hand-held tester main switch ON. NOTE: Do not start the engine. Select the ACTIVE TEST mode on the hand-held tester. HINT: Please refer to the hand-held tester operator's manual for further details. If you have no hand-held tester, connect the positive (+) and negative (-) leads from the battery to the fuel pump connector (see «FUEL PUMP»(ref-239091-S02930303862006072600000) ). Connect the battery to the injector with SST (wire) for 15 seconds, and measure the injection volume with a graduated cylinder. Test each injector 2 or 3 times. SST 09842-30080 Injection volume: 76 to 92 cm 3 (4.6 to 5.6 cu in.) per 15 seconds. Difference between each injector: 16 cm 3 (1.0 cu in.) or less If the injection volume is not as specified, replace the injector.
2. INSPECT LEAKAGE In the above condition, disconnect the tester probes of SST (wire) from the battery and check the fuel leak from the injector. SST 09842-30080 Fuel drop: 1 drop or less per 12 minutes. Turn the ignition switch OFF. Disconnect the negative (-) terminal cable from the battery. Remove SST and fuel tube connector. SST 09268-41047 Disconnect the hand-held tester from the DLC3. Reconnect the fuel tube (fuel tube connector). CAUTION: Disconnect the fuel tube connector (quick type) observing the precaution (see «SFI SYSTEM»(ref-239091-S33576169842006072600000) ). Reconnect the fuel pipe clamp to the fuel tube connector.

1. INSTALL INJECTORS AND DELIVERY PIPES Apply a light coat of spindle oil or gasoline to a new O-ring, and install it to each injector. Install the 2 spacers and 4 new grommets to the cylinder head. Apply a light coat of spindle oil or gasoline to the place where a delivery pipe touches the O-ring. Push the injector to the delivery pipes turning the injector (Scheme 104) Then install the 4 injectors. Position the injector connector downward. Attach the delivery pipe together with the 4 injectors to the cylinder head. Temporarily install the 2 bolts holding the delivery pipe to the cylinder head. Check that the injectors rotate smoothly. HINT: If injectors do not rotate smoothly, the possible cause is incorrect installation of the O-ring. Replace the O-ring. Position the injector connector downward. Tighten the 2 bolts holding the delivery pipe to the cylinder head. Torque: 20 N.m (205 kgf.cm, 15 ft.lbf) Connect the 4 injector connectors.
