INSPECTION
1. INSPECT INJECTOR INJECTION
CAUTION:
Keep injector clean of sparks during the test.
(a) Disconnect the fuel inlet hose (fuel tube connector) from
the fuel filter.
CAUTION:

Perform disconnecting operations of the fuel tube
connector (quick type) after reading the precautions
(See page SF-1).

Prevent the retained pressure in the fuel pipe line
from splashing inside the engine compartment.
(b) Use a new fuel main hose and take out the fuel tube con-
nector from its hose.
Part No. 23271-50150
(c) Connect SST (hose) and fuel tube connector to the fuel
filter outlet.
SST 09268-41047
CAUTION:
Perform connecting operations of the fuel tube connector
(quick type) after reading the precautions (See page
SF-1).
HINT:
Use the vehicle's fuel filter.
(d) Remove the pressure regulator from the delivery pipe.
(e) Install the O-ring to the fuel inlet of the pressure regulator.
(f) Connect SST (hose) to the fuel inlet of the pressure regu-
lator with SST (union) and the 2 bolts.
SST 09268-41047 (09268-41091)
Torque: 7.5 N´m (80 kgf´cm, 66 in.´lbf)
(g) Connect the fuel return hose to the fuel outlet of the pres-
sure regulator.

(h) Install the O-ring to the injector.
(i) Connect SST (adaptor and hose) to the injector, and hold
the injector and union with SST (clamp).
SST 09268-41047 (09268-41110, 09268-41300)
(j) Put the injector into the graduated cylinder.
CAUTION:
Install a suitable vinyl hose onto the injector to prevent
gasoline from splashing out.
(k) Connect the TOYOTA hand-held tester or OBD II scan
tool to the DLC3.
(l) Connect the battery negative (-) cable to the battery.
(m) Turn the ignition switch ON, and press the TOYOTA
hand-held tester or OBD II scan tool main switch ON.
NOTICE:
Do not start the engine.
(n) Select ACTIVE TEST mode on the TOYOTA hand-held
tester or OBD II scan tool.
(o) Please refer to the TOYOTA hand-held tester or OBD II
scan tool operator's manual for further details.
(p) If you have no TOYOTA hand-held tester or OBD II scan
tool, connect the positive (+) and negative (-) leads from
the battery to the fuel pump connector
(See page SF-7).
(q) Connect SST (wire) to the injector and the battery for 15
seconds, and measure the injection volume with a gra-
duated cylinder. Test each injector 2 or 3 times.
SST 09842-30070
Volume: 56 - 69 cm
3 (3.4 - 4.2 cu in.) per 15 seconds
Difference between each injector:
13 cm
3 (0.8 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 12 minutes

(b) Turn the ignition switch OFF.
(c) Disconnect the negative (-) terminal cable from the bat-
tery.
(d) Remove SST and fuel tube connector.
SST 09268-41047, 09842-30070
(e) Disconnect the TOYOTA hand-held tester or OBD II scan
tool from the DLC3.
(f) Reconnect the fuel inlet pipe (fuel tube connector) to the
fuel filter.

INSTALLATION
1. INSTALL INJECTORS AND DELIVERY PIPES
NOTICE:

Be careful not to drop the injectors when installing
the delivery pipes.

Since the O-ring may be stuck to the injector, do not
put a side load on it at the removal.
(a) Install a new grommet to each injector.
(b) Apply a light coat of gasoline to new O-rings and install
them to each injector.
(c) While turning the injector clockwise and counterclock-
wise, push it to the delivery pipes. Install the 8 injectors.
(d) Position injector connector outward.
(e) Place the 4 spacers and 8 new insulators on the intake
manifold.
(f) Place the 2 delivery pipes and the injectors assemblies on
the lower intake manifold.
(g) Temporarily install the 4 nuts.
(h) Install the front fuel pipe with the bolt, the 4 new gaskets
and the 2 union bolts.
Torque:
39 N´m (400 kgf´cm, 29 ft´lbf) for union bolts
7.5 N´m (80 kgf´cm, 66 in.´lbf) for bolt
(i) Install the bolt holding the clamp on the fuel return pipe to
the LH delivery pipe.
Torque: 7.5 N´m (80 kgf´cm, 66 in.´lbf)
(j) Check that the injectors rotate smoothly.
HINT:
If injectors do not rotate smoothly, the probable cause is incor-
rect installation of O-rings. Replace the O-rings in that case.
(k) Position the injector connector outward.
(l) Tighten the 4 nuts holding the delivery pipes to the lower
intake manifold.
Torque: 21 N´m (214 kgf´cm, 15 ft´lbf)
(m) Connect the 8 injectors connectors.
