SPARK TEST
CHECK THAT SPARK OCCURS
(a) Disconnect the high±tension cord from the distributor.
(b) Hold the end approx. 12.5 mm (0.50 in.) from body of vehicle.
(c) See 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 time.
If the spark does not occurs, perform the test as follows:

INSPECTION OF SPARK PLUGS
NOTICE:
wNever use a wire brush for cleaning
wNever attempt to adjust the electrode gap on used
spark plug.
wSpark plug should be replaced every 100,000 km
I60,000 miles).
6. If not using a megger:
(a) Quickly race the engine to 4,000 rpm five times.
(b) Remove the spark plug.
(See step 2 on page IG±11)
(C) Visually check the spark plug.
If the electrode is dry ... Okay
If the electrode is wet ... Proceed to step 3 INSPECTION OF HIGH±TENSION CORDS
1. CAREFULLY REMOVE HIGH±TENSION CORDS BY
THEIR RUBBER BOOTS FROM SPARK PLUGS
NOTICE: Pulling on or bending the cords may damage the
conductor inside.
1. INSPECT ELECTRODE
A. If using a megger (insulation resistance motor):
Measure the insulation resistance.
Correct insulation resistance: 10 M
or more
If the resistance is less than specified, proceed step 2. 2. INSPECT HIGH±TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance.
Maximum resistance: 25 k
per cord
If the resistance is greater than maximum, replace the high±
tension cord.

4. INSPECT ELECTRODE GAP
Maximum electrode gap: 1.3 mm, (0.051 in.)
If the gap is greater than maximum, replace the spark plug.
Correct electrode gap of new spark plug:
1.1 mm (0.043 in.)
If adjusting the gap of a new spark plug, bend only the base
of the ground electrode. Do not touch the tip.
5. CLEAN SPARK PLUGS
If the electrode has traces of wet carbon, allow it to dry and
then clean with a spark plug cleaner.
Air pressure: Below6 kg/cm
2 (85 psi, 588 kPa)
Duration: 20 seconds or less
HINT: If there are traces of oil, remove it with gasoline before
using the spark plug cleaner.3. VISUALLY INSPECT SPARK PLUGS
Check the spark plug for thread or insulation damage.
If abnormal, replace the spark plug.
Recommended spark plug: ND PQ2OR
NGK6CPR6EP11
6. INSTALL SPARK PLUGS
Using a 16 mm plug wrench, install and torque the spark
plug.
Torque: 180 kg±cm (13 ft±Lb, 18 N±m)
2. REMOVE SPARK PLUGS
Using a 16 mm plug wrench, remove the spark plug.
