1. Remove the No. 44 (15 A) fuse from the under-hood
fuse/relay box,
Press the clutch pedal all the way in (M/T), and turn
the ignition switch to "St8rt". The staner 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 starter does not crank the engine, go to step 3.
Check the battery, battery positive cable, ground,
and the wire connections for looseness and cor-
rosion.
Test again. lf the stsner stilldoes not crank the en-
gine, go to step 4.
Bypass the ignition switch circuit as follows {make
sure the transmission is in neutral)
Unplug the connector (BLKMHT wire and solenoid
terminal) trom the staner. Then connect a jumper
wire from the batterv positive (+ ) terminal to the
solenoid terminal. The starter should crank the
engine.
a It the stsrter still does not crank the engine,
replace it and diagnose its internal problems,
a lf the starter cranks the engine. go to step 5.

NOTE: The air temperature must be between 59 and
100oF {15 and 38'C) betore testing.
Recommended Procedure:
a Use a starter system tester.
a Connect and operate the equipment in accordance
with the manufacturer's instructions.
a Test and troubleshoot as described.
Alternate Procodure:
a Use the following equipment;- Ammeter, O-400 A- Voltmeter. O-20 V (accurate within O,1 volt)- Tachometer, O- 1 2OO rpm
a Hook up voltmeter and ammeter as shown.
NEGATIVE TERMINAL
NOTE: Atter this test, or any subsequent repalr,
reset the ECM to clear any codes (see section 1 1).

BRUSHES

Startel Field Winding Test
Check for continuity between the brushes. lf there's
no continuity. replace the armature housing.
Check for continuily between each brush and the ar-
mature housing (ground). lf there is continuity,
replace the armature housing.
Overrunning Clutch InsPection
Slide the overrunning clutch along the shaft.
Does it move freely? It not, replace it.
Rotate the overrunning clutch both ways.
Does it lock in one direction and rotate smoothly in
reverse? It it does not lock in either direction or it
locks in both directions, repl8c€ it,
lf the starter drive gear is worn or damaged, replace
the overrunning clutch assembly; the gear is not
available separately.
Check the condition ot the flywheel or torque con-
vener ring gear it the starter drive gear teeth are
damaged.

lgnition Control Module (lCM) Input Test
NOTE:
a See section 1 1 if the malfunction indicator lamp (MlLl
has been reported on.a Perform 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 distributo. ignition (Dl) cap, the rotor,and the leak cover.
2. Disconnect the BLK/YEL, WHT/BLU, YEL/GRN, andBLU wires from the lCM.
3. Turn the ignition switch ON {ll}. Check for voltage
between the BLK/YEL wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check the BLKiYEL
wire between the ignition switch and the lCM.a It there is battery voltage, go to step 4,

4. Turn the ignition switch ON (ll). Check for voltage
between the WHT/BLU wire and body ground.
There should be battery voltage.
a lf there is no battery voltage, check:- ignition coil.- WHT/BLU wire between the ignition coil and
tcM.
a lf there is battery voltage, go to step 5.
5. Disconnect the 32P connector from the ECM, and
check for continuity on the YEUGRN wire between
the ICM and ECM.
There should be continuity.
6. Check for continuity on the YEL/GRN wire to bodygrouno.
There should be no continuity.
7.Reconnect the ECM 32P connector.
Disconnect the gauge assembly 13P connector,
TCM 26P connector, and cruise control l4P connector.
9. Check for continuity on the BLU wire between the
ICM and tachometer.
There should be continuity.
'10. Check for continuity on the BLU wire to body ground.
There should be no continuity.
1 1 . lf all the tests are normal, reconnect the connectors,
and replace the lCM.
