Ch6ck Starter Engag€mont;
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.
(cont'd)
4.
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).

Starting System
Starter Test (cont'dl
Check Cranking rpmr
Engine speed during cranking should be above 1OO rpm.
lJ speed is too low, check for:
a Loose batlery or starter terminals
a Excessively worn starter brushes
a Open circuit in commutator segments
a Dirty or damaged helical spline or drive gear
a Defective drive gear overrunning clutch
Check Starter Disengagement:
Press the clutch pedal all the way in (M/T), turn rhe igni
tion switch to "lll" and release to "11".
The starter drive gear should disengage from the flywheel
or torque converter ring gear when you release the key.
It the drive gear hangs up on the flywheel or torque con-
verter ring gear, check for:
a Solenoid plunger and switch mallunction
a Dirty drive gear assembly or damaged overrunning
clutch
5. Check for an open in the BLK/WHT wire circuit be
tween the starter and ignition switch, and con-
necrors,
6. Check the ignition switch (see page 23-71).
7. On cars with automatic transmission, check the A/Tgear position switch (neutral position switch) and
connector. On cars with manualtransmission, check
the starter cut relay, clutch interlock switch, and
connectors.
NOTE: Check the No. 42 (40 A) fuse in the under,hoodfuse/relay box for the starter cut relay.
Check Jor Wear and Damage:
The starter should crank the engine smoothly and stead,ily. lf the starter engages, but cranks the engine errati
cally, remove it. Inspect the starter, drive gear, andllywheel or torque converter ring gear lor damage.
a Check the drive gear overrunning clutch for binding
or slipping when the armature is rotated with the drivegear held. Replace the gears i{ damaged.
Check CJanking Voltage and Current Draw:
Cranking voltage should be no less than 8.O volts.
Current draw should be no more than * amperes.* 1.2 kW: 27O A
1 .4 kW: 360 A
It cranking voltage is too low, or current draw too high,check for:
a Dead or low charged batterya Open circuit in starter armature commutator segmentsa Starter armalure dragging
a Shorted armature windinga Excessive drag in engine
