Starting System
Startel Test
NOTE: The air temDerature must be between 59 8nd
10OoF (15 and 38oC) before testing.
Recommendsd Procodure:
a Use a staner svstem tester.
a Connect and operate the equipment in accordance
with the manutacturer's instructions.
a Test and troubleshoot as described.
Altohato Procedure:
a Use the following equipment:- Ammeter. 0-4OO A- Voltmeter, O- 20 V {accurate within 0.1 volt)
- Tachometer, O- 120O rpm
a Hook up voltmeter and ammeter as shown'
NEGATIVE TERMINAL
NOTE: After this test, or any subsequent repair,
reset the ECM to clear any codes (see section 1 1)

Chock Stan€r Engag6ment:
1. Disconnect the 2-P connector (ignition coil primary
lead) from the distributor.
Press the clutch pedal allthe way in (M/T), and turn
the ignition switch to "Start". The starter should
crank the engine.
NOTE: On cars equipped with manual transmission,
the engine will not crank unless the clutch pedal is
fully depressed.
lf the staner does not crank the engine go to step 3.
Check the baftery, battery positive cable, ground,
and the wire connections for looseness and cor-
rosion,
Test again. lf the starter still does not crank the en-
gine, go to step 4.
Bvpass the ignition switch citcuit as follows {make
sure the transmission is in neutral):
Unplug the connector (BLK/WHT wire and solenoid
terminsl) trom the starter. Then connect a jumper
wire from the battery positive ( + ) terminal to the
solenoid terminal. The starter should crank the
engrne.
a lf the starter still does not crank the engine,
replace it and diagnose its internal problems.
a lf the starter cranks the engine, go to step 5.

Distributor Installation
Coat a new O-ring with engine oil, then install it.
Slip the distributor into position.
NOTE: The lugs on the end of the distributor and
its mating grooves in the camshaft end are both off-
set to eliminate the possibility ot installing the dis-
tributor 18Oo out of time.
DISTRIBUTOR END CAMSHAFT END
Install the mounting bolts and tighten them tem-
porarily.
Connect the 2-P and 8-P connectors to the dis-
tributor.

5. Connect the ignition wires as shown.
Set the timing with a timing light (se€ page 23-89).
After setting the timing, tighten the mounting bolts.

Spark Plug Inspection
1. Inspect the electrodes and ceramic insulator for:
. rmproper gap. Oil-touling. Carbon deposits. Cracked centerelectrode insulatorDamagedgask6t
Burned or worn electlodes may be caused by:. Advanced ignition timing. Loose spark plug. Plug heat range too low. Insufficient cooling
Fouled plug may be caused by:. Retarded ignition timing. Oil in combustion chamber. lncorrect spark plug gap. Plug heat range too high. txcessive idling/low speed running. Clogged air cleaner element. Deteriorated ignition coil or ignition wires
Check the electrode gap.
Bl88l engine:
a Adjust the gap with a suitable gapping tool.
Electrode Gap
Standard: 1.0-1.1 mm (O.O39-0.O43 in)
1.1 mm{0.0,$ in)
Replace the plug if the center electrode is round-
ed as shown below:
ROUNDEDELECTROOE
Bl8Cl engine:
a Make sure that the '1.4 mm (0.055 in) wire-typeplug gauge does not go into the gap for the plati-
num tip plug. lf the gauge goes into the gap, do
not attempt to adjust the side electrode; replace
the plug with a new one. Use only the spark plugs
listed below.
ROUNDEO ELECTRODE
Electrode GapStandard: 1 .2-'l .3 mm{0.047 -O.051 in)Service Limit: 1.4 mm{0.055 in)
CAUTION: Do not use a blade-type plug gaugs, it
may damage the platinum tip of the center olectrodo.

3. Apply a small quantity ol anti-seize compound to the
plug threads.
Screw the plugs into the cylinder head iingef-tight,
then torque them to 18 N.m (1.8 kgf.m, 13lbf.ft).

Replacement
Disconnect the 3-P connector trom the vehicle speed
sensor {VSS).
Remove ihe two mounting bolts, then remove the
VSS.

NOTE: The VSS drive link is a very small paru
caretul not to lose it.

Engine Oil Pressure Switch Test
1. Remove the YEL/RED wile from the engine oil pres-
sure switch.
ENGI'{E OIL PRESSURE SWITCH
Check tor continuitv between the positive torminal
and the engine {gtound) with the ignhion swhch OFF.
a lf there is continuity, go to step 3.
a lf there is no continuity, replace the switch.
Check for continuity again, this time with th€ engine
runnrng.
a lf there is continuity, go to step 4,
a lf there is no continuity, the switch is OK.
Make sure engine oil level is OK, then check engin€
oil pressure (s€e section 8).
a lf engine oil pressure is OK, replace the switch'
a lf engine oil pressure is low, check the sngine oil
pump (see section 8) and, if necessary, replac€ it.
