INSPECTION PROCEDURE
1 Check spark plug and spark of misfiring cylinder.
PREPARATION:
(a) Remove the ignition coil and high−tension cord.
(b) Remove the spark plug.
CHECK:
(a) Check the spark plug type.
(b) Check for carbon deposits on electrode.
(c) Check the electrode gap.
OK:
(1) Twin ground electrodes type.
Recommended spark plug:
ND K16TR11
NGK BKR5EKB−11
(2) No large carbon deposit present. Not wet with
gosoline or oil.
(3) Electrode gap: 1.0 − 1.1 mm (0.039 − 0.043 in.)
PREPARATION:
(a) Install the spark plug to the ignition coil or high−tension
cord.
(b) Disconnect the injector connector.
(c) Ground the spark plug.
CHECK:
Check if the spark occurs while the engine is being cranked.
NOTICE:
To prevent excess fuel being injected from the injectors
during this test, don’t crank the engine for more than 5 − 10
sec. at a time.
OK:
Spark jumps across electrode gap.
NG Replace or check ignition system (See page
IG−1).

7. FUEL SYSTEM
(a) When disconnecting the high pressure fuel line, a large
amount of gasoline will spill out, so observe these proce-
dures:
(1) Put a container under the connection.
(2) Slowly loosen the connection.
(3) Disconnect the connection.
(4) Plug the connection with a rubber plug.
(b) When connecting the flare nut or union bolt on the high
pressure pipe union, observe these procedures:
(1) (Union Bolt Type)
Always use a new gasket.
(2) (Union Bolt Type)
Tighten the union bolt by hand.
(3) (Union Bolt Type)
Tighten the union bolt to the specified torque.
Torque: 29 N·m (300 kgf·cm, 22 ft·lbf)
(4) (Flare Nut Type)
Apply a light coat of engine oil to the flare and tight-
en the flare nut by hand.
(5) (Flare Nut Type)
Using SST, tighten the flare nut to the specified
torque.
SST 09631−22020
Torque: 30 N·m (310 kgf·cm, 22 ft·lbf)
HINT:
Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).
(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 cylinder head
as shown in the illustration.
