ON−VEHICLE INSPECTION
SPARK TEST
CHECK THAT SPARK OCCURS
(a) Disconnect high−tension cord from the distributor.
(b) Hold the end approx. 12.5 mm (0.50 in.) from engine ground
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 se-
conds at a time.
If the spark does not occur, perform the test as follows:
SPARK TEST

Maximum resistance: 25 kW per cord
CHECK POWER SUPPLY TO IGNITION COIL AND Check wiring between ignition switch to ignition coil
IGNITER and igniter.
1. Turn ignition switch to ON.
2. Check that there is battery voltage at ignition coil
positive (+) terminal.
CHECK RESISTANCE OF IGNITION COIL Replace the ignition coil.
(See page IG−8)
Resistance: Cold Hot
Primary 0.36 − 0.55 W 0.45 − 0.65 W
Secondary 9.0 − 15.4 kW 11.4 − 18.1 kW
CHECK RESISTANCE OF SIGNAL GENERATOR Replace the distributor housing assembly.
(PICKUP COIL)

CHECK AIR GAP OF DISTRIBUTOR Replace the distributor housing assembly.
(See page IG−9)
Air gap: 0.2 − 0.4 mm (0.008 − 0.016 in.)
CHECK IGT SIGNAL FROM ECM Check wiring between ECM, distributor and igniter, and
(See page EG2−138, EG2−156 or EG2−174) then try another ECM.

HIGH−TENSION CORDS INSPECTION
1. DISCONNECT HIGH−TENSION CORDS FROM SPARK
PLUGS
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 con-
ductor inside.
2. DISCONNECT HIGH−TENSION CORDS FROM
DISTRIBUTOR CAP AND IGNITION COIL
(a) Using a screwdriver, lift up the lock claw and disconnect the
holder from the distributor cap (ignition coil).
(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 conduc-
tor inside.
• Do not wipe any of the oil from the grommet after the
high−tension cord is disconnected.
3. INSPECT HIGH−TENSION CORD RESISTANCE
Using an ohmmeter, measure the resistance.
Maximum resistance:
25 k W per cord
If the resistance is greater than maximum, check the termi-
nals. If necessary, replace the high−tension cord.
4. RECONNECT HIGH−TENSION CORDS TO DISTRIBUTOR
CAP AND IGNITION COIL
(a) Assemble the holder and grommet.

IGNITION SYSTEM − (22R−E)
(b) Align the spline of the distributor (ignition coil) with the spline
of the holder, and push in the cord.
NOTICE: Check that the holder is correctly installed to the
grommet and distributor cap as shown in the illustration.
(c) Check that the lock claw of the holder is engaged by lightly
pulling the holder.
5. RECONNECT HIGH−TENSION CORDS TO SPARK
PLUGS
SPARK PLUGS INSPECTION
1. REMOVE SPARK PLUGS
2. CLEAN AND INSPECT SPARK PLUGS
(a) Clean the spark plugs with a spark plug cleaner or wire brush.
(b) Inspect the spark plugs for electrode wear, thread damage
and insulator damage.
If a problem is found, replace the plugs.
Spark plug:
W16EXR−U for ND
BPR5EY for NGK

3. ADJUST ELECTRODE GAP
Carefully bend the outer electrode to obtain the correct elec-
trode gap.
Correct electrode gap:
0.8 mm (0.031 in.)
4. INSTALL SPARK PLUGS

IGNITION COIL INSPECTION
NOTICE: ”Cold” and ”Hot” in the following sentences express
the temperature of the coils themselves. ”Cold” is from−10°C
(14°F) to 50°C (122°F) and ”Hot” is from 50°C (122°F) to 100°C
(212°F).
1. DISCONNECT HIGH−TENSION CORD
2. CLEAN COIL AND CHECK FOLLOWING:
(a) Check for cracks or damage.
(b) Check the terminals for carbon tracks.
(c) Check the high−tension cord hole for carbon deposits and
corrosion.
3. MEASURE PRIMARY COIL RESISTANCE

positive (+) and negative (−) terminals.
Primary coil resistance (Cold):
0.36−0.55 W
Primary coil resistance (Hot):

4. MEASURE SECONDARY COIL RESISTANCE
Using an ohmmeter, measure the resistance between the
positive (+) terminal and high−tension terminal.
Secondary coil resistance (Cold):

DISTRIBUTOR INSPECTION
NOTICE: ”Cold” and ”Hot” in the following sentences express
the temperature of the coils themselves. ”Cold” is from−10°C
(14°F) to 50°C (122°F) and ”Hot” is from 50°C (122°F) to 100°C
