If Your Engine Won't Start
Diagnosing why your engine won't start falls into two areas, depending
on what you hear when you turn the
key to START (III): You hear nothing, or almost
nothing. The engine's starter
motor does not operate at all, oroperates very slowly. You can hear the starter motor
operating normally, but the engine
does not start up and run. Nothing Happens or the Starter
Motor Operates Very Slowly
When you turn the ignition switch to START (III), you do not hear the
normal noise of the engine trying to start. You may hear a clicking sound
or series of clicks, or nothing at all.Check these things:
Check the transmission interlock.
The transmission must be in Park or Neutral or the starter will not

operate.
Turn the ignition switch to ON (II).
Turn on the headlights and check their brightness. If the headlights are very dim or don't light at all,
the battery is discharged. See
Jump Starting on page 200. Turn the ignition switch to START
(III). If the headlights do not dim,
check the condition of the fuses. If
the fuses are OK, there is proba-
bly something wrong with the electrical circuit for the ignition
switch or starter motor. You will
need a qualified technician todetermine the problem. (See
Towing on page 213.)
If the headlights dim noticeably or
go out when you try to start theengine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec- tions (see page 162 ). You can
then try jump starting the car from a booster battery (see page 200 ).

If Your Engine Won't Start, Jump Starting

The Starter Operates Normally In this case, the starter motorsounds normal when you turn the
ignition switch to START (III), but
the engine does not run. Are you using the proper starting
procedure? Refer to Starting the
Engine on page 119 . Do you have fuel? Turn the
ignition switch to ON (II) for a
minute and watch the fuel gauge.
The low fuel level warning light may not be working, so you were
not reminded to fill the tank. There may be an electrical
problem, such as no power to the
fuel pump. Check all the fuses (see page 208).
If you find nothing wrong, you will
need a qualified technician to find
the problem. See Towing on page
213.
Jump Starting
If your car's battery has run down,
you may be able to start the engine by using a booster battery. Although
this seems like a simple procedure,
there are several precautions you should take. Follow the directions
closely.
You cannot start a Honda by pushing or pulling it. To jump start your car:
1. Open the hood and check the physical condition of the battery(see page 162 ). In very cold
weather, check the condition of the electrolyte. If it seems slushyor like ice, do not try jump starting
until it thaws.

If a battery sits in extreme cold, the
electrolyte inside can freeze.

Attempting to jump start with a frozen battery can cause it to rupture or
explode.

2. Turn off all the electrical acces- sories: heater, A/C, stereo system
lights, etc. Put the transmission in Neutral or
Park and set the parking brake.

NOTICE

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.ProCarManuals.coms t Main Menu Table of Contents

Jump Starting

3. Connect one jumper cable to the positive ( + ) terminal on the
booster battery. Connect the other
end to the positive ( + ) terminal
on your Honda's battery. 4. Connect the second jumper cable
to the negative ( — ) terminal on
the booster battery. Connect theother end to the grounding strap
as shown. Do not connect this
jumper cable to any other part of the engine.
5. If the booster battery is in another car, have an assistant start that car
and run it at a fast idle.
BOOSTER
BATTERY

6. Start your car. If the starter motor still operates slowly, check the
jumper cable connections to make sure they have good metal-to-
metal contact.
7. Once your car is running, discon- nect the negative cable from your
car, then from the booster battery.
Disconnect the positive cable from
your car, then the booster battery.

If Your Engine Overheats

The pointer of your car's tempera-
ture gauge should stay in the mid-

range under most conditions. It may

go higher if you are driving up a long
steep hill on a very hot day. If it

climbs to the red mark, you should
determine the reason.

Driving with the temperature gauge
pointer at the red mark can cause serious damage to your engine.
Your car can overheat for several

reasons, such as lack of coolant or a

mechanical problem. The only

indication may be the temperature

gauge climbing to or above the red

mark. Or you may see steam or
spray coming from under the hood.

In either case, you should take

immediate action.
1. Safely pull to the side of the road.
Put the transmission in neutral or
park and set the parking brake.
Turn off the heating and cooling system and all other accessories.
Turn on the hazard warning indicators.
2. If you see steam and/or spray coming from under the hood, turnoff the engine.
3. 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 (climbing a long, steep hill on a
hot day with the A/C running, for example), the engine should start
to cool down almost immediately. If it does, wait until the tempera-
ture gauge comes down to the mid
point then continue driving.

NOTICE

Steam and spray from an

overheated engine can

seriously scald you.

Do not open the hood if steam

is coming out.ProCarManuals.coms t Main Menu Table of Contents

If Your Engine Overheats

4. If the temperature gauge stays at the red mark, turn off the engine.
5. Wait until you see no more signs of steam or spray, then open the

hood.

6. Look for any obvious coolant leaks, such as a split radiator hose.
Everything is still extremely hot, so use caution. If you find a leak, it
must be repaired before you continue driving (see Towing on
page 213 ).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page150 ). If the level is below the
MIN mark, add coolant to half-way
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have toadd coolant to the radiator. Let the
engine cool down until the pointer reaches the middle of the tempera-
ture gauge, or lower, before check-
ing the radiator.
9. Using gloves or a large heavy cloth, turn the radiator capcounterclockwise, without pushing
down, to the first stop. This
releases any remaining pressure in
the cooling system. After the pressure releases, push down on
the cap and turn it until it comesoff. 10.Start the engine and set the
temperature control lever tomaximum. Add coolant to the
radiator up to the base of the filler
neck. If you do not have the
proper coolant mixture available,
you can add plain water. Remember to have the coolingsystem drained and refilled with
the proper mixture as soon as you
can.

11. Put the radiator cap back on tightly. Run the engine and watch
the temperature gauge. If it goesback to the red mark, the engine
needs repair. (See Towing on
page 213.)
12.If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has gone down, add coolant to theMAX mark. Put the cap back on

tightly.

Taking Care of the Unexpected

Removing the radiator cap
while the engine is hot can
cause the coolant to spray out, seriously scalding you.
Always let the engine and radiator cool down before
removing the radiator cap.ProCarManuals.comMain Menu s t Table of Contents

Low Oil Pressure

This indicator should light when the ignition is ON (II), and go out after
the engine starts. It should nevercome on when the engine is running.
If it starts flashing, it indicates that
the oil pressure dropped very low for a moment, then recovered. If the
indicator stays on with the engine
running, it shows that the engine has
lost oil pressure and serious engine damage is possible. In either case,
you should take immediate action.
Running the engine with low oil
pressure can cause serious mechanical damage almost immediately. Turn offthe engine as soon as you can safely get
the car stopped.

1. Safely pull off the road and shut off the engine.
2. Let the car sit for a minute. Open the hood and check the oil level(see page 146). Although oil level
and oil pressure are not directly
connected, an engine that is very
low on oil can lose pressure during cornering and other driving

maneuvers.

3. If necessary, add oil to bring the level back to the full mark on thedipstick (see page 146). 4. Start the engine and watch the oil
pressure light. If the light does nogo out within ten seconds, turn of
the engine. There is a mechanical problem that needs to be repaired
before you can continue driving.

Charging System Indication

This indicator should come on when the ignition is ON (II), and go out
after the engine starts. If it comes on
brightly when the engine is running,it indicates that the charging system
has stopped charging the battery. Immediately turn off all electrical
accessories: radio, heater, A/C, rear defogger, cruise control, etc. Try not
to use other electrically-operated
controls such as the power windows. Keep the engine running and takeextra care not to stall it. Starting the
engine will discharge the battery
rapidly. By eliminating as much of the
electrical load as possible, you can
drive several miles before the
battery is too discharged to keep the engine running. Drive to a servicestation or garage where you can get
technical assistance.
