1.When reassembling the dislributor, install the distri-
butor rotor so on the shaft that it faces in the direc-
tion shown (toward the No. 1 cylindetl,
2.Align the index mark on the distributor housing with
the index mark on the end of the shaft.

Control Module (lCMl Input Test
NOTE:
a See section I 1 if the malfunction indicator lamD (MlL)
blinks.
a Pertorm an input test for the ignition control module
(lCM) after finishing the fundamental tests for the ig-
nition system and the fuel and emissions systems.
a The tachometer should operate normally.
1. Remove the distributor cap, the distributor rotor, and
the leak cover.
2. Disconnect the BLK/YEL, WHT/BLU, YEL/GRN, and
BLU wires from the lCM.
3. Turn the ignition switch ON. Check for voltage be-
tween the BLK/YEL wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check the BLK^/EL
wire between the ignition switch and the lCM.
a lf there is battery voltage, go to step 4.

4.Turn the ignition switch ON. Check for voltage be-
tween the WHT/BLU wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check:- lgnition coil- WHT/BLU wire between the ignition coil and
the ICM
a lf there is battery voltage. go to step 5.
Check the YEL/GRN wire between the ECM and the
tcM.
Check the BLU wi.e between the tachometer and the
rcM.
It all tests are normal, replace the lCM.

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
