ON-VEHICLE INSPECTION
1. INSPECT INJECTOR OPERATION
Check operation sound from each injector.
(1) With the engine running or cranking, use a sound
scope to check that there is a normal operating
noise in proportion to engine speed.
(2) If you have no sound scope, you can check the
injector transmission operation with your finger.
If no sound or unusual sound is heard, check the wiring connec-
tor, injector or injection signal from the ECM.
2. INSPECT INJECTOR RESISTANCE
(a) Disconnect the injector connector.
(b) Using an ohmmeter, measure the resistance between the
terminals.
Resistance:
13.4 - 14.2 W at 20°C (68°F)
If the resistance is not as specified, replace the injector.
(c) Reconnect the injector connector.

positive (+) and negative (-) leads from the battery to the
fuel pump connector (See page MF-5).
(q) Connect SST (wire) to the injector and battery for 15 se-
conds, and measure the injection volume with a gra-
duated cylinder. Test each injector 2 or 3 times.
SST 09842-30070
Volume:
39 - 49 cm
3 (2.4 - 3.0 cu in.) per 15 sec.
Difference between each injector:
5 cm
3 (0.3 cu in.) or less
If the injection volume is not as specified, replace the injector.
2. INSPECT LEAKAGE
(a) In the condition above, disconnect the tester probes of
SST (wire) from the battery and check the fuel leakage
from the injector.
SST 09842-30070
Fuel drop:
1 drop or less per 3 minutes
(b) Disconnect the negative (-) terminal cable from the bat-
tery.
(c) Remove the SST.

INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPE
(a) Install a new grommet to the injector.
(b) Apply a light coat of gasoline to an O-ring, and install it
to the injector.
(c) While turning the injector left and right, install it to the de-
livery pipe. Install the 4 injectors.
(d) Place the 2 spacers and 4 insulators in position on the cyl-
inder head.
(e) Place the injectors together with the delivery pipe on the
cylinder head.
(f) Check that the injectors rotate smoothly.
HINT:
If the injectors do not rotate smoothly, the probable cause is in-
correct installation of O-rings. Replace the O-rings.
(g) Position the injector connector upward.
(h) Install the 2 bolts.
Torque: 19 N´m (190 kgf´cm, 14 ft´lbf)
2. CONNECT ENGINE WIRE
(a) Connect the 4 injector connectors.
(b) Connect the engine wire to the surge tank stay.
3. CONNECT FUEL INLET HOSE TO DELIVERY PIPE
(a) Install 2 new gaskets and the inlet hose with the union
bolt.
Torque: 30 N´m (300 kgf´cm, 23 ft´lbf)
(b) Connect the engine wire clamp to the No.2 engine hang-
er.
4. CONNECT FUEL RETURN HOSE TO FUEL RETURN

INSPECTION
INSPECT FUEL TANK AND LINE
(a) Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.
(b) Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leakage
or tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and the tube connections are as shown in the il-
lustration.
(f) Make sure the hose clamps do not interfere with the tank,
tubes, hoses and other parts.
If a problem is found, repair or replace the parts as necessary.
