1. INSPECT SPARK TEST
Check that the spark occurs.
(1) Disconnect the high±tension cord from the spark plug.
(2) Remove the spark plug.
(3) Install the spark plug to the high±tension cord.
(4) Ground the spark plug.
(5) See if spark occurs while engine is being cranked.
NOTICE:
To prevent gasoline from being injected from injectors during this test, crank the engine for no more
than 5 ± 10 seconds at time.
If the spark does not occur, do the test as follows:

(a) Remove the V±bank cover.
(b) Disconnect the high±tension cords from the spark plugs.
(1) Using needle±nose pliers, disconnect the cord
clamp from the engine wire protector.
(2) Disconnect the high±tension cords from the spark
plugs.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.
(3) Disconnect the high±tension cords from the clamp.
(c) Disconnect the high±tension cords from the ignition coils.
(1) Using a screwdriver, lift up the lock claw and discon-
nect the holder from the ignition coils.
(2) Disconnect the high±tension cord at the grommet.
NOTICE:

Pulling on or bending the cords may damage the con-
ductor inside.

Do not wipe any of the oil from the grommet after the
high±tension cord is disconnected.
