INSTALLATION
1. CHECK NO. 1 CYLINDER TO TDC/COMPORESSION
If necessary, remove the cylinder head cover, and check these
conditions:
Turn the crankshaft pulley clockwise and align its
groove with the timing mark ”0” of the oil pump cov-
er.
Verify that the timing marks with 1 and 2 dots are in
straight line on the cylinder head surface as shown
in the illustration.
If not, turn the crankshaft 1 revolition (360 °) and align the mark
as above.
2. INSTALL DISTRIBUTOR
(a) Install a new O−ring to the distributor.
HINT:
Always use a new O−ring when installing the distributor.
(b) Align the protrusion of the distributor housing with the
groove on the driven gear.
(c) Apply a light coat of engine oil on the O−ring.
(d) Install the distributor with the 2 bolts.
Torque: 19 N·m (195 kgf·cm, 14 ft·lbf)
3. INSTALL DISTRIBUTOR CAP
4. RECONECT HIGH−TENSION CORDS TO DISTRIBU-
TOR CAP
5. CONNECT DISTRIBUTOR CONNECTOR
6. CHECK IGNITION TIMING (See page EM−11)

RESISTANCE
Using an ohmmeter, measure the resistance between termi-
nals.
Resistance (NE and NE):
Cold: 1,630 − 2,740 Ω
Hot: 2,065 − 3,225 Ω
If the resistance is not as specified, replace the crankshaft posi-
tion sensor.

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. INSPECT SPARK TEST
Check that the spark occurs.
(1) Disconnect the high−tension cords from the spark
plug.
(2) Remove the spark plug.
(3) Install the spark plug to each high−tension cord.
(4) Ground the spark plug.
(5) Check if spark occurs while engine is being
cranked.
NOTICE:
To prevent excess fuel being injected from the injectors
during this test, do not crank the engine for more 1 − 2 se-
conds at a time.
If the spark does not occur, perform the test as follows:

2. INSPECT HIGH−TENSION CORDS
(a) Remove the air cleaner cap and MAF meter assembly.
(b) Disconnect the high−tension cords from the 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 conduc-
tor inside.
(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.
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.
(d) Inspect the high−tension cord resistance.
Using an ohmmeter, measure the resistance.
Maximum resistance:
25 kΩ per cord
If the resistance is greater than maximum, check the terminals.
If necessary, replace the high−tension cord.
