DISASSEMBLY
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 the switching
at the battery side.
If operation is not as specified, replace the fuel pump and/or
plate.
3. REMOVE FUEL PUMP FROM FUEL PUMP BRACKET
(a) Disconnect the fuel pump connector.
(b) Pull off the lower side of the fuel pump from the pump
bracket.
(c) Disconnect the fuel hose from the fuel pump, and remove
the fuel pump.
(d) Remove the rubber cushion from the fuel pump.
4. REMOVE FUEL PUMP FILTER FROM FUEL PUMP
(a) Using a small screwdriver, remove the clip.
(b) Pull out the pump filter.

ON−VEHICLE INSPECTION
1. INSPECT IAC VALVE OPERATION
(a) Initial conditions:
Engine at normal operating temperature
Idle speed set correctly
Transmission in neutral range
(b) Using SST, connect terminals TE1 and E1 of the
DLC1.
SST 09843−18020
(c) After engine rpm are kept at 1,000 − 1,500 rpm for 5 se-
conds, check that they return to idle speed.
If the rpm operation is not as specified, check the IAC valve, wir-
ing and ECU.
(d) Remove SST.

2. INSPECT IAC VALVE RESISTANCE
NOTICE:
”Cold” and ”Hot” in the following sentences express the
temperature of the coils themselves. ”Cold” is from −10°C
(14°F) to 50°C (122°F) and ”Hot” is from 50°C (122°F) to
100°C (212°F).
(a) Disconnect the IAC valve connector.
(b) Using an ohmmeter, measure the resistance between ter-
minal +B and other terminals (RSC, RSO).
Resistance:
Cold: 21.5 − 28.5Ω
Hot: 17.0 − 24.5Ω
If resistance is not as specified, replace the IAC valve.
(c) Reconnect the IAC valve connector.

PRECAUTION
1. BEFORE WORKING ON FUEL SYSTEM, DISCON-
NECT NEGATIVE (−) TERMINAL CABLE FROM BAT-
TERY
HINT:
Any diagnostic trouble code retained by the computer will be
erased when the negative (−) terminal cable is removed from
the battery.
Therefore, if necessary, read the diagnosis before removing 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 LEATH-
ER PARTS
4. MAINTENANCE PRECAUTIONS
(a) In the event of engine misfire, these precautions should
be taken.
(1) Check proper connection to battery terminals, etc.
(2) After repair work, check that the ignition coil termi-
nals and all other ignition system lines are recon-
nected securely.
(3) When cleaning the engine compartment, be espe-
cially careful to protect the electrical system from
water.
(b) Precautions when the handling heated oxygen sensors.
(1) Do not allow the oxygen sensor to drop or hit
against an object.
(2) Do not allow the sensor to come into contact with
water.
If Vehicle is Equipped with Mobile Radio System (ham, cb, etc.)
If the vehicle is equipped with a mobile communication system,
refer to the precaution in the IN section.
5. 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.

(c) Observe these 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.
(d) Install the injector to the delivery pipe and intake manifold
as shown in the illustration.
(e) Check that there are no fuel leaks after doing mainte-
nance anywhere on the fuel system.
(1) Connect the TOYOTA hand−held tester to the
DLC3.
(2) Turn the ignition switch ON and push the TOYOTA
hand−held tester main switch ON.
NOTICE:
Do not start the engine.
(3) Select the active test mode on the TOYOTA hand−
held tester.
(4) Please refer to the TOYOTA hand−held tester oper-
ator ’s manual for further details.
(5) If you have no TOYOTA hand−held tester, connect
the positive (+) and negative (−) leads from the bat-
tery to the fuel pump connector.
(See page SF−10)
(6) Pinch the fuel return hose.
The pressure in the high pressure line will rise to
approx. 400 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.

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
