FUEL SYSTEM (3MZ-FE)
PRECAUTION
1. PRECAUTION
(a) Before working on the fuel system, disconnect the engine wire No. 3 (battery negative terminal) from
battery.
(b) Do not smoke or work near open flame when working on the fuel system.
(c) Keep gasoline away from the rubber or leather parts.
2. DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:

Do not disconnect any parts of the fuel system pres-
sure until you have discharging the fuel system pres-
sure.

Even after discharge the fuel pressure, place a shop
rag over fittings as you separate them in order to re-
duce risk of fuel spray on yourself or in the engine
compartment.
(a) Disconnect the engine wire No. 3 (battery negative termi-
nal).
(b) Remove the circuit opening relay from the engine room
relay block.
(c) Connect the engine wire No. 3 (battery negative terminal).
Torque: 5.4 NVm (55 kgfVcm, 48 in.Vlbf)
(d) Start the engine. After the engine has stopped on its own,
turn the ignition switch OFF.
HINT:
There is a case that DTC P0171 (system to lean) is output.
(e) Check that the engine does not start.
(f) Remove the fuel tank cap, then let the air out of the fuel
tank.
(g) Disconnect battery negative terminal.
(h) Reinstall the circuit opening relay.
3. FUEL SYSTEM
(a) When disconnecting the high fuel pressure line, a large
amount of gasoline will spill out. So observe these proce-
dures.
(1) Work in order to prevent gasoline from spilling out.
(2) Disconnect the fuel pump tube (see page 11-20).
(3) Drain the fuel remaining inside the fuel pump tube.

(4) In order to prevent the disconnected fuel pump tube
from being damaged and foreign objects from being
introduced, cover the disconnected fuel pump tube
with a vinyl or plastic bag.
(5) Place a tray under the vehicle or point of disconnec-
tion to catch any fuel that may spill.
(6) Put a container under the connection.
(b) Take the following precautions when removing and instal-
ling the fuel injectors.
NOTICE:
Never reuse the O-ring.
(1) When installing a new O-ring on the fuel injector, be
careful not to damage it.
(2) Coat a new O-ring with spindle oil or gasoline be-
fore installing. Never use engine oil, gear oil or
brake oil.
(c) Install the fuel injector to the fuel delivery pipe and intake
manifold as shown in the illustration. Before installing the
fuel injector, be sure to apply spindle oil or gasoline to the
place where the fuel delivery pipe or intake manifold
touches the O-ring of the fuel injector.
(d) Take the following precautions when disconnecting the
quick connector.
(1) Remove the fuel pipe clamp.
(2) Check the pipe and around the quick connector for
dirt or mud before disconnecting them. Remove the
dirt if necessary.

(09268-41250, 09268-41200, 09268-41220)
(h) Wipe up any gasoline.
(i) Reconnect the engine wire No. 3 (battery negative termi-
nal).
(j) Connect the hand-hand tester to the DLC3.
(k) Measure the fuel pressure.
Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
If the pressure is high, replace the fuel pressure regulator.
If the pressure is low, check the fuel hose connections, fuel
pump, fuel filter and fuel pressure regulator.
(l) Disconnect the hand-held tester from the DLC3.
(m) Start the engine.
(n) Measure the fuel pressure at idle.
Fuel pressure:
304 to 343 kPa (3.1 to 3.5 kgf/cm
2, 44 to 50 psi)
(o) Stop the engine.
(p) Check that the fuel pressure remains as specified for 5
minutes after the engine has stopped.
Fuel pressure: 147 kPa (1.5 kgf/cm
2, 21 psi) or more
If the pressure is not as specified, check the fuel pump, pres-
sure regulator and/or fuel injectors.
(q) After checking the fuel pressure, disconnect the battery
negative terminal and carefully remove SST and the fuel
tube connector to prevent gasoline splash.
(r) Reconnect the No. 1 fuel pipe (the fuel tube connector).
CAUTION:
After taking the precautions, connect the quick connector.
