INSTALLATION
1. INSTALL FRONT ACTUATOR
(a) Check that the outermost rack tooth of the shift fork is
virtually above the center line of the actuator installation
hole.
(b) Using a dry cell battery, alig n the matchmark on the pinion
with the center line of the actuator.
NOTICE:
If the pinion of the actuator is not in the specified
place, the actuator is difficult to be installed.
Do not supply the battery positive voltage between
terminals.
If the matchmark comes to the extension limit of the
rotation, do not electrify moreover.
(c) Install a new O−ring to the actuator.
(d) Apply a light coat of gear oil on the O −ring.
(e) Apply MP grease to the gear part of the actuator.
(f) Install the actuator to the differential with the 2 nuts and bolt, so that the outermost rack tooth of the shift fork will
fit matchmark of the pinion of the actuator.
HINT:
Do not damage the O −ring of the actuator.
Torque: 26 N·m (270 kgf·cm, 20 ft·lbf)

PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM, DISCON-
NECT NEGATIVE (−) TERMINAL CABLE FROM THE
BATTERY.
HINT:
Any diagnostic trouble code retained by the computer will be
erased when the negative ( −) terminal cable is disconnected.
Therefore, if necessary, read the diagnosis before disconnect-
ing the negative ( −) terminal cable from the battery.
2. DO NOT SMOKE OR WORK NEAR AN OPEN FLAME WHEN WORKING ON FUEL SYSTEM.
3. KEEP GASOLINE AWAY FROM RUBBER OR
LEA TH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) In event of engine misfire, these precautions should be taken.
(1) Check proper connection of battery terminals, etc.
(2) Handle high −tension cords carefully.
(3) After repair work, check that the ignition coil termi- nals and all other ignition system lines are recon-
nected securely.
(4) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Precautions when handling the oxygen sensor. (1) Do not allow the oxygen sensor to drop or hit
against an object.
(2) Do not allow the sensor to come in contact with wa- ter.
5. IF VEHICLE IS EQUIPPED WITH MOBILE RA-
DIO
SYSTEM (HAM, CB, ETC.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
6. AIR INDUCTION SYSTEM
(a) Separation of the engine oil dipstick, oil filler cap, PCV hose, etc. may cause the engine to run out of tune.
(b) Disconnection, looseness or cracks in the parts of the air
induction system between the throttle body and cylinder
head will allow air suction and cause the engine to run out
of tune.
7. ELECTRONIC CONTROL SYSTEM
(a) Before removing SFI wiring connectors, terminals, etc., first disconnect the power by either turning the ignition
switch OFF or disconnecting the negative ( −) terminal
cable from the battery.

HINT:
Always check the diagnostic trouble code before disconnecting
the negative ( −) terminal cable from the battery.
(b) When installing the battery, be especially careful not to in-
correctly connect the positive (+) and negative ( −) cables.
(c) Do not permit parts to receive a severe impact during re- moval or installation. Handle all SFI parts carefully, espe-
cially the ECM.
(d) Do not be careless during troubleshooting as there are numerous transistor circuits and even slight terminal con-
tact can further troubles.
(e) Do not open the ECM cover.
(f) When inspecting during rainy weather, take care to pre-
vent entry of water. Also, when washing the engine
compartment, prevent water from getting on the SFI parts
and wiring connectors.
(g) Parts should be replaced as an assembly.
(h) Care is required when pulling out and inserting wiring con-
nectors.
(1) Release the lock and pull out the connector, pulling
on the connectors.
(2) Fully insert the connector and check that it is locked.
(i) When inspecting a connector with a volt/ohmmeter (1) Carefully take out the water −proofing rubber if it is
a water−proof type connector.
(2) Insert the test probe into the connector from the wir-
ing side when checking the continuity, amperage or
voltage.
(3) Do not apply unnecessary force to the terminal.
(4) After checking, install the water−proofing rubber on
the connector securely.
(j) Use SST for inspection or test of the injector or its wiring connector.

INSPECTION
1. REMOVE SECOND SEATS
2. REMOVE SCUFF PLATE
3. REMOVE SIDE GARNISH
4. REMOVE STEP PLATE
5. DISCONNECT FLOOR MATS
6. REMOVE FLOOR SERVICE HOLE COVER
Remove the 3 screws and service hole cover.
7. DISCONNECT FUEL PUMP AND SENDER GAUGE CONNECTOR
8. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between the ter-
minals 5 and 6. Resistance: 0.2 − 3.0 Ω at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump.
9. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 6 of
the connector, and the negative ( −) lead to terminal 5. Check
that the fuel pump operates.
NOTICE:
These tests must be performed quickly (within 10 se-
conds) to prevent the coil from burning out.
Keep the fuel pump as far away from the battery as
possible.
Always perform switching at the battery side.
If operation is not as specified, replace the fuel pump.
