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 almostnothing. The engine's starter
motor does not operate at all, oroperates 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. 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 headlightsare very dim or don't light at all,
the battery is discharged. See

Jump Starting on page 202.
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 to determine the problem. (See
Towing on page 215.)
If the headlights dim noticeably or
go out when you try to start the engine, either the battery is dis-
charged or the connections are
corroded. Check the condition of
the battery and terminal connec-
tions (see page 164). You can
then try jump starting the car from a booster battery (see page 203).

If Your Engine Won't Start, Jump Starting
The Starter Operates Normally In this case, the starter motor'sspeed sounds normal, or even faster
than normal, when you turn the
ignition switch to START (III), but
the engine does not run.
Are you using the proper startingprocedure? 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 211).
If you find nothing wrong, you will
need a qualified technician to find
the problem. See Towing on page
215.
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,
you should take several precautions.
You cannot start a Honda by pushing or pulling it. To jump start your car, follow these
directions closely:
1. Open the hood and check the physical condition of the battery(see page 164). In very cold
weather, check the condition of
the electrolyte. If it seems slushy or 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.

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.

Taking Care of the Unexpected
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.

Jump Starting

3. Connect one jumper cable to the positive ( + ) terminal on thebooster battery. Connect the otherend to the positive ( + ) terminal
on your Honda's battery. 4. Connect the second jumper cable
to the negative ( — ) terminal onthe 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. 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.comMain Menu Table of Contents s t

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 215).
7. If you don't find an obvious leak, check the coolant level in the
radiator reserve tank (see page113). If the level is below the
MIN mark, add coolant to halfway
between the MIN and MAX marks.
8. If there was no coolant in the reserve tank, you may also have to
add 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 cap
counterclockwise, 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 comes
off.
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 goes
back to the red mark, the engine
needs repair. (See Towing on
page 215.)
12.If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has
gone down, add coolant to the MAX 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 Table of Contents s t

Low Oil Pressure Indicator
This indicator should light when the ignition is ON (II), and go out after
the engine starts. It should never
come 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 off
the engine as soon as you can safely get
the car stopped.
1. Safely pull off the road and shut off the engine. Turn on the hazard
warning indicators.
2. Let the car sit for a minute. Open the hood and check the oil level(see page 112). 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 148). 4. Start the engine and watch the oil
pressure indicator. If the lightdoes not go out within ten seconds,
turn off the engine. There is a
mechanical problem that needs to
be repaired before you can
continue driving. (See Towing on page 215.)

Charging System Indicator

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 take
extra 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 top discharged to keep the
engine running. Drive to a service station or garage where you can get
technical assistance.

Malfunction Indicator Lamp
MALFUNCTION INDICATOR LAMP
This indicator comes on for a few seconds when you turn the ignition
switch ON (II). If it comes on at any
other time, it indicates one of the
engine's emissions control systems
may have a problem. Even though
you may feel no difference in your car's performance, it can reduce
your fuel economy and cause your car to put out excessive emissions.
Continued operation may cause
serious damage. If you have recently refueled your
vehicle, the cause of this indicator coming on could be a loose or
missing fuel fill cap. Check the cap
and tighten it until it clicks. Replacethe fuel fill cap if it is missing.
Tightening the cap will not make the indicator turn off immediately; it
takes three driving trips.
If the indicator remains on past three
driving trips, or the fuel cap was not
loose or missing, have the vehicle
checked by the dealer as soon as possible. Drive moderately until the
dealer has inspected the problem.
Avoid full-throttle acceleration and driving at high speed. You should also have the dealer
inspect your vehicle if this indicator
comes on repeatedly, even though it may turn off as you continue driving.

If you keep driving with the malfunc-
tion indicator lamp on, you can damage
your car's emission controls and engine. Those repairs may not he covered by
your car's warranties.
