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.

8. FUEL SYSTEM
(a) When disconnecting the high fuel pressure line, a large
amount of gasoline will spill out, so observe the following
procedures:
(1) Disconnect the fuel pump connector.
(2) Start the engine. After the engine has stopped onits own, turn off the ignition switch.
(3) Put a container under the connection.
(4) Slowly loosen the connection.
(5) Disconnect the connection.
(6) Plug the connection with 2 rubber plugs.
(7) Reconnect the fuel pump connector.
(b) When connecting the union bolt on the high pressure pipe
union, observe the following procedures:
(1) Always use a new gasket.
(2) Tighten the union bolt by hand.
(3) Tighten the union bolt to the specified torque.
Torque: 29 N·m (300 kgf·cm, 21 ft·lbf)
(c) When connecting the flare nut on the high pressure pipe union, observe the following procedures:
(1) Apply a light coat of engine oil to the flare and tight-
en the flare nut by hand.
(2) Using SST, tighten the flare nut to the specified torque.
SST 09631−22020
NOTICE:
Do not rotate the fuel pipe, when tightening the flare nut.
Torque: 30 N·m (310 kgf·cm, 22 ft·lbf)
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).

(d) Observe the following precautions when removing and
installing the injectors.
(1) Never reuse the O −ring.
(2) When placing a new O −ring on the injector, take
care not to damage it in any way.
(3) Coat a new O −ring with spindle oil or gasoline be-
fore installing −never use engine, gear or brake oil.
(e) Install the injector to the delivery pipe and intake manifold
as shown in the illustration.
(f) Check that there are no fuel leaks after doing mainte- nance anywhere on the fuel system.
(1) Remove the fuse cover on the instrument panel.
(2) Connect the TOYOTA hand− held tester to the
DLC3.
(3) Turn the ignition switch ON and TOYOTA hand −
held tester main switch ON.
NOTICE:
Do not start the engine. (4) Select the active test mode on the TOYOTA hand−held tester.
(5) Please refer to the TOYOTA hand −held tester oper-
ator ’s manual for further details.
If you have no T OYOTA hand−held tester, connect the positive
(+) and negative ( −) leads from the battery to the fuel pump con-
nector (See page SF−14 ).
(6) Pinch the fuel return hose. The pressure in the high
pressure line will rise to approx. 392 kPa (4 kgf/cm
2,
57 psi). In this state, check to see that there are no
leaks from any part of the fuel system.
NOTICE:
Always pinch the hose. Avoid bending as it may cause the
hose to crack.
(7) Turn the ignition switch to LOCK.
(8) Disconnect the TOYOTA hand −held tester from the
DLC3.
