ON−VEHICLE INSPECTION
1. CHECK THAT SPARK OCCURS
(a) Disconnect the high −tension cords (from the ignition coil)
from the distributor cap.
(b) Hold the end approx. 12.5 mm (0.50 in.) from the body ground.
(c) Check if spark occurs while engine is being cranked.
HINT:
To prevent gasoline from being injected from injectors during
this test, crank the engine for no more than 1 − 2 seconds at a
time.
If the spark does not occur, do the test as follows:

4. DISCONNECT THROTTLE CABLE
5. REMOVE NO.2 AND NO.3 CYLINDER HEAD COVERS
Remove the 4 bolts and head covers.
6. DISCONNECT HIGH −TENSION CORDS FROM SPARK
PLUGS
(a) Remove the 2 mounting bolts of the No.1 and No.2 cord clamps.
(b) Disconnect the high −tension cords at the rubber boot.
Do not pull on the cords.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.

(b) Disconnect the high−tension cord at the grommet.
Do not pull on the cord.
NOTICE:
Pulling on or bending the cords may damage the conductor
inside.Do not wipe any of the oil from the grommet after the
high −tension cord is disconnected.
8. INSPECT HIGH−TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance. Maximum resistance: 25 k Ω per cord
If the resistance is greater than maximum, check the terminals.
If necessary, replace the high −tension cord.
9. RECONNECT HIGH− TENSION CORDS TO DISTRIBU-
TOR CAP AND IGNITION COIL
(a) Assemble the holder and grommet.
HINT:
Connect the high− tension cords to the distributor cap as shown
in the illustration.
(b) Align the spline of the distributor (ignition coil) with the spline of the holder, and push in the cord.
