(a) Install the spark plug to the high − tension cord.
(b) Disconnect injector connector.
(c) Ground spark plug.
CHECK:
Check if spark occurs while engine is being cranked.
NOTICE:
To prevent excess fuel being injected from the injectors
during this test, do not crank the engine for more than 5 −
10 seconds at a time.
OK:
Spark jumps across electrode gap.
NG Replace or check ignition system (See page
IG−1).
OK
2 Check voltage of ECM terminal for injector of failed cylinder.

(4) Flare Nut Type:
Apply a light coat of engine oil to the flare nut, and
tighten the flare nut by hand.
(5) Flare Nut Type:
Using SST, tighten the flare nut to specified torque.
SST 09631−22020
NOTICE:
Do not rotate the fuel pipe, when tightening the flare nut.
Torque: 34 N·m (350 kgf·cm, 25 ft·lbf)
28 N·m (285 kgf·cm, 21 ft·lbf) for SST
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
(c) Observe the following 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.
(4) Install the injector to the delivery pipe and intake
manifold as shown in the illustration.

(g) Wipe off any splattered gasoline.
(h) Connect the TOYOTA hand−held tester to the DLC3.
(i) Reconnect the negative (−) terminal cable to the battery.
(j) Turn the ignition switch ON.
(k) Measure the fuel pressure.
Fuel pressure:
301 − 347 kPa (3.1 − 3.5 kgf/cm
2, 44 − 50 psi)
If pressure is high, replace the fuel pressure regulator.
If pressure is low, check these parts:
Fuel hoses and connections
Fuel pump
Fuel filter
Fuel pressure regulator
(l) Remove the TOYOTA hand−held tester from the DLC3.
(m) Start the engine.
(n) Measure the fuel pressure at idle.
Fuel pressure:
301 − 347 kPa (3.1 − 3.5 kgf/cm
2, 44 − 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 pressure is not as specified, check the fuel pump, pressure
regulator and/or injectors.
(q) After checking fuel pressure, disconnect the negative (−)
terminal cable from the battery and carefully remove the
SST to prevent gasoline from splashing.

INSTALLATION
1. INSTALL INJECTORS AND SPACERS
(a) Install new insulator and grommet to each injector.
(b) Apply a light coat of gasoline onto 2 new O−rings, and
install them to each injector.
(c) Place the 2 spacers in position on the cylinder head.
(d) Push in the 4 injectors to the cylinder head.
2. INSTALL DELIVERY PIPE AND FUEL INLET HOSE
(a) Place the delivery pipe together with the 2 bolts between
the intake manifold and cylinder head.
(b) While turning the injector left and right, push it to the deliv-
ery pipe.
(c) Temporarily install the 2 bolts holding the delivery pipe to
the cylinder head.
(d) 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.
(e) Position the injector connector upward.
