INSPECTION
1. INSPECT FUEL PUMP RESISTANCE
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance: 0.2 − 3.0 Ω at 20°C (68°F)
If the resistance is not as specified, replace the fuel pump and/
or set plate.
2. INSPECT FUEL PUMP OPERATION
Connect the positive (+) lead from the battery to terminal 1 of
the connector, and the negative (−) lead to terminal 2. Check
that the fuel pump operates.
NOTICE:
These tests must be done quickly (within 10 seconds) to
prevent the coil from burning out.Keep the fuel pump as far
away from the battery as possible.Always do switching at
the battery side.
If operation is not as specified, replace the fuel pump and/or
plate.

INSTALLATION
1. INSTALL FUEL PRESSURE REGULATOR
(a) Apply a light coat of gasoline to a new O−ring, and install
it to the pressure regulator.
(b) Attach the pressure regulator to the LH delivery pipe.
(c) Check that the pressure regulator rotates smoothly.
NOTICE:
If it does not rotate smoothly, the O−ring may be pinched,
so remove the pressure regulator and repeat steps (a) to (c)
above.
(d) Install the pressure regulator with the 2 bolts.
Torque: 8 N·m (80 kgf·cm, 71 in.·lbf)
(e) Install the engine wire with the bolt.
2. CONNECT FUEL RETURN HOSE TO FUEL

NOTICE:
Be sure to insert the hose up to the stopper and clip it.

INSPECTION
1. INSPECT INJECTOR RESISTANCE
Using an ohmmeter, measure the resistance between the ter-
minals.
Resistance:
Approx. 13.8 Ω at 20°C (68°F)
If the resistance is not as specified, replace the
injector.
2. INSPECT INJECTOR INJECTION
CAUTION:
Keep injector clear of sparks during the test.
(a) Disconnect the fuel inlet pipe from the fuel tube.
(b) Connect SST (attachment and hose) to the fuel tube.
SST 09268−41046 (09268−52011)
(c) Connect the fuel return hose, SST (union) and SST
(hose) to the fuel pressure regulator.
SST 09268−41046 (09268−41091)
(d) Install the O−ring to the injector.
(e) Connect SST (union and hose) to the injector, and hold
the injector and union with SST (clamp).
SST 09268−41046
(f) Put the injector into the graduated cylinder.
HINT:
Install a suitable vinyl tube onto the injector to prevent gasoline
from splashing out.
(g) Connect the TOYOTA hand−held tester to the DLC3.
(See on−vehicle inspection in fuel pump)
(h) Connect SST (wire) to the injector and battery for 15 se-
conds, 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 sec.
Difference between each injector:
6 cm
3 (0.4 cu in.) or less
If the injection volume is not as specified, replace the injector.
3. INSPECT LEAKAGE
(a) In the condition above, disconnect the test 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 minute
(b) Turn the ignition switch to LOCK.
(c) Disconnect the negative (−) terminal cable from the bat-
tery.

INSTALLATION
1. TEMPORARILY INSTALL INJECTORS AND
DELIVERY PIPES
(a) Install 2 new grommets to each injector.
(b) Apply a light coat of spindle oil or gasoline to 2 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 6 injectors.
(d) Position the injector connector outward.
(e) Place the 4 spacers in position on the intake manifold.
(f) Place the delivery pipes with the 6 injectors in position on
the intake manifold.
(g) Temporarily install the 4 bolts holding the delivery pipes
to the intake manifold.
(h) 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.
(i) Position the injector connector outward.
2. CONNECT INJECTOR CONNECTORS
3. INSTALL FUEL PIPE AND TIGHTENING
DELIVERY PIPE HOLDING BOLTS
(a) Install the fuel pipe with 4 new gaskets and the 2 union
bolts.
Torque: 34.3 N·m (350 kgf·cm, 25 ft·lbf)
(b) Tighten the 4 bolts holding the delivery pipes to the intake
manifold.
Torque: 13 N·m (130 kgf·cm, 10 ft·lbf)

INSPECTION
INSPECT FUEL TANK AND LINE
(a) Check the fuel lines for cracks or leakage, and all connec-
tions for deformation.
(b) Check the fuel tank vapor vent system hoses and connec-
tions for looseness, sharp bends or damage.
(c) Check the fuel tank for deformation, cracks, fuel leakage
or tank band looseness.
(d) Check the filler neck for damage or fuel leakage.
(e) Hose and pipe connections are as shown in the illustra-
tion.
