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.

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.

NOTE: Atter this test, or any subsequent repalr,
reset the ECM to clear any codes (see section 1 1).

Engine Coolant Temperature (ECT) Gauge
Gauge Test
NOTE: Refer to page 23-123 for the wiring description of
the engine coolant temperature (ECT) gauge circuit dia-
gram.
1. Check the No. 25 (7.5 A) fuse in the under-dash
fuse/relay box before testing.
2. Make sure the ignition switch is OFF, then discon-
nect the YEL/GRN wire trom the ECT gauge send-
ing unit and ground it with a jumper wire.
YEL/GRN WIRESENDING UNIT
Turn the ignition switch ON (ll).
Check that the pointer of the ECT gauge starts mov-
ing toward the "H" mark.
CAUTION: Turn the ignition switch OFF before the
pointer reaches "H" on the gauge dial. Failure to do
so may damage the gauge.
a lf the pointer of the gauge does not move at all,
check lor an open in the YEL or YEL/GRN wire.
lf the wires are OK, replace the ECT gauge.
a lf the ECT gauge works, test the ECT sending
unrt.
ECT Sending Unit Test
Disconnect the YEL/GRN wire from the ECT send-
ing unit.
With the engine cold, use an ohmmeter to measure
resistance between the positive terminal and the en-
gine (ground).
Check the temperature ol the coolant.
Run the engine and measure the change in resistance
with the engine at operating temperature (the radi-
ator fan comes on).
5. It the obtained readings are substantially different
from the sDecifications above, replace the ECT send-
Ing unrt.
