PRECAUTION
1.PRECAUTION
(a)Before working on fuel system, disconnect negative (±) battery cable.
(b)Do not smoke or work near fire when handling the fuel system.
(c)Keep gasoline away from rubber or leather parts. 2.DISCHARGE FUEL SYSTEM PRESSURE
CAUTION:
Do not disconnect any part of the fuel system until
you have discharged the fuel system pressure.
Even after discharging the fuel pressure, place a
shop rag over fittings as you separate them to reduce
risk of fuel spray on yourself or in the engine compart-
ment.
(a)Disconnect the fuel pump connector.
(b)Start the engine. After the engine has stopped, turn the ignition switch OFF.
(c)Disconnect the negative (±) battery cable.
(d)Connect the fuel pump connector.
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)Discharge the pressure in the fuel system. (See step 2)
(2) Disconnect the fuel pump tube. (See page 11±93)
(3) Drain the fuel that remained inside the fuel pump
tube.
(4) Cover the disconnected fuel pump tubes with a vinyl or a plastic bag to prevent damage and dirt.
(5) Place a tray under the vehicle or point of disconnec- tion to catch any fuel that may spill.

INSPECTION
1.INSPECT FUEL INJECTOR ASSY
(a)Inspect injector resistance (1)Using an ohmmeter, measure the resistance be-tween the terminals.
Resistance: 13.4 to 14.2 at 20 C (68 F)
If the resistance is not as specified, replace the injector.
(b)Inspect injector inspection
CAUTION:
This test involves high±pressure fuel and electricity. Take
every precaution regarding safe handling of both the fuel
and the electricity. Preform this test in a safe area, and
avoid any sparks or flame. Do not smoke.
(1)Obtain new No. 1 fuel pipe (part No. 23901±0H040)and remove the fuel tube connector from the pipe.
(2)Install the fuel tube connector to SST (hose), then connect the tube connector and the fuel pipe.
SST09268±41047 (95336±08070)
CAUTION:
Connect the fuel tube connector (quick type) after observ-
ing the precautions to prevent fuel from spraying.
(3)Install the O±ring to the injector.
(4)Connect SST (union and hose) to the injector, andhold the injector and the union with SST (clamp)
SST09268±41047 (09268±41110, 09268±41300, 95336±08070)
(5)Put the injector into a graduated cylinder.
CAUTION:
Install a suitable vinyl tube onto the injector to contain gas-
oline spray. (6)Operate the fuel pump.(See Page 11±19)

4. DISCONNECT FUEL TANK RETURN TUBE (1AZ±FSE ENGINE TYPE)
(a) Remove the tube joint clip, and pull out the fuel return tube.
NOTICE:
Check if there is any dirt or mud around the connector
before this operation and remove the dirt as neces-
sary.
Be careful of mud because the fuel tube joint has an
O±ring which seals the pipe and connector that can
be contaminated.
Do not use any tool in this operation.
Do not bend or twist the nylon tube. Protect the con-
nector by covering it with a vinyl or plastic bag.
When the pipe and connector are stuck, push and pull
the connector to release and pull the connector out
carefully.

he engine stops.
HINT:
If fuel leakage could be found on specific parts, replace them with new \
parts.
(b) While cranking or when starting the engine, check that there is no leaks from\
any part of the fuel sys-
tem.
HINT:
If fuel leakage could be found on specific parts, replace them with new pa\
rts.
(c) Disconnect the fuel hose from the common rail.
(d) While cranking the engine, check fuel leaks from the return pipe.
HINT:
If there is fuel leakage, replace the common rail.
(e) Connect the hand±held tester to the DLC3.
(f) Start the engine and push the hand±held tester main switch ON.
(g) Select the FUEL LEAK test of ACTIVE TEST mode on the hand±held tester\
.
(h) If you do not have the hand±held tester, depress the accelerator pedal quickly and fully to increase the engine speed at maximum and keep it for 2 seconds. Repeat this opera\
tion several times.
(i) Check that there are no leaks from any part of the fuel system.
NOTICE:
If the leakage from the return pipe is less than 10 cc (0.6 cu in.) in\
a minute, it is acceptable.
HINT:
If fuel leakage could be found on specific parts, replace them with new \
parts.
(j) Reconnect the fuel hose to the common rail.
