Diagnosing why the engine won’t
start falls into two areas, depending
on what you hear when you turn the
ignition switch to the START (III)
position: You hear nothing, or almost
nothing. The engine’s starter
motor does not operate at all, or
operates very slowly.
You can hear the starter motor
operating normally, or the starter
motor sounds like it is spinning
faster than normal, but the engine
does not start up and run.
Wh en you turn the ignition switch to
the START (III) position, you do not
hear the normal noise of the engine
trying to start. You may hear a
clicking sound, a series of clicks, or
nothing at all. Check
the transmission interlock.
The transmission must be in Park
or neutral or the starter will not
operate.
Turn the ignition switch to the ON
(II) position. Turn on the
headlights, and check their
brightness. If the headlights are
very dim or do not come on at all,
the battery is discharged. See
on page . If
the headlights dim noticeably or
go out when you try to start the
engine, either the battery is
discharged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page ). You can
then try jump starting the vehicle
from a booster battery (see page
).
In this case, the starter motor’s
speed sounds normal, or even faster
than normal, when you turn the
ignition switch to the START (III)
position, but the engine does not run.
Are you using a properly coded
key? An improperly coded key will
cause the immobilizer system
indicator in the dash panel to blink
rapidly(seepage ).
Check these things: Turn
the ignition switch to the
START (III) position. If the
headlights do not dim, check the
condition of the fuses. If the fuses
areOK,thereisprobably
something wrong with the
electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician to
determine the problem. See
on page . 426

There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses
(see page ).
Ifyoufindnothingwrong,youwill
need a qualified technician to find
the problem. See
on page . Although this seems like a simple
procedure, you should take several
precautions.
You cannot start your vehicle by
pushing or pulling it.
Put the transmission in neutral or
Park, and set the parking brake. Turn of f all the electrical acces-
sories: heater, A/C, climate
control, audio system, lights, etc. Open the hood, and check the
physical condition of the battery.
In very cold weather, check the
condition of the electrolyte. If it
seems slushy or f rozen, do not try
jump starting until it thaws.

A battery can explode if you do
not follow the correct procedure,
seriously injuring anyone
nearby.
Keep all sparks, open flames,
and smoking materials away
from the battery.
If a battery sits in extreme cold, the
electrolyte inside can f reeze.
Attempting to jump start with a f rozen
battery can cause it to rupture.

´ ´ Keep the ends of the jumper cables
away from each other and any metal
on the vehicle until everything is
disconnected. Otherwise, you may
cause an electrical short.Once the vehicle is running,
disconnect the negative cable f rom
the engine hanger on your vehicle,
then from the booster battery.
Disconnect the positive cable f rom
your vehicle, then f rom the
booster battery. Start your vehicle. If the starter
motor still operates slowly, check
that the jumper cables have good
metal-to-metal contact. If the booster battery is in another
vehicle, have an assistant start
that vehicle and run it at a fast idle.
Connect the second jumper cable
to the negative ( ) terminal on
the booster battery. Connect the
other end to the engine hanger as
shown. Do not connect this jumper
cable to any other part of the
engine.
The numbers in the illustration show
you the order to connect the jumper
cables.
Connect one jumper cable to the
positive ( ) terminal on your
vehicle’s battery. Connect the
other end to the positive ( )
terminal on the booster battery. 5.

If you see steam and/or spray
coming f rom under the hood, turn
of f the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
If you do not see steam or spray,
leave the engine running, and
watch the temperature gauge. If
the high heat is due to overloading,
the engine should start to cool
down almost immediately. If it
does, wait until the temperature
gauge comes down to the midpoint,
then continue driving.
The pointer of your vehicle’s
temperature gauge should stay in
the midrange. If it climbs to the red
mark, you should determine the
reason.
If the vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to or above the red
mark. Or you may see steam or
spray coming f rom under the hood.
Saf ely pull to the side of the road.
Put the transmission in Park, and
set the parking brake. Turn of f all
accessories, and turn on the
hazard warning lights.
