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.

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.

Fuses

ABS FUSE BOX

The ABS fuse box is in the engine
compartment on the right side.
Checking and Replacing Fuses

If something electrical in your car
stops working, the first thing you
should check for is a blown fuse.
Determine from the chart on pages 213 and 214 , or the diagram on the
fuse box lid, which fuse or fuses control that component. Check those
fuses first, but check all the fuses
before deciding that a blown fuse is not the cause. Replace any blown
fuses and check the component's
operation.

1. Turn the ignition switch to LOCK (0). Make sure the headlights and
all other accessories are off.
2. Remove the cover from the fuse box. 3. Check each of the large fuses in
the under-hood fuse box by
looking through the top at the wire inside. Removing these fuses
requires a Phillips-head screw-driver.

Emission Controls

Exhaust Emission Controls

The exhaust emission controls include four systems: PGM-FI,
Ignition Timing Control, ExhaustGas Recirculation and Three Way
Catalytic Converter. These four
systems work together to control the
engine's combustion and minimize
the amount of HC, CO, and NOx that
comes out the tailpipe. The exhaust
emission control systems are
separate from the crankcase and
evaporative emission control

systems.

PGM-FI System

The PGM-FI System uses sequential multiport fuel injection.It has three subsystems: Air Intake,
Engine Control, and Fuel Control.
The Powertrain Control Module (PCM) uses various sensors to
determine how much air is going
into the engine. It then controls how
much fuel to inject under all operat-
ing conditions. Ignition Timing Control System
This system constantly adjusts the ignition timing, reducing the amountof HC, CO and NOx produced.
Exhaust Gas Recirculation (EGR)
System

The Exhaust Gas Recirculation (EGR) system takes some of the
exhaust gas and routes it back into
the intake manifold. Adding exhaust
gas to the air/fuel mixture reduces
the amount of NOx produced when
the fuel is burned.
Three Way Catalytic Converter
The three way catalytic converter is in the exhaust system. Through
chemical reactions, it converts HC,CO, and NOx in the engine's exhaust
to carbon dioxide (CO 2), dinitrogen
(N 2), and water vapor. Replacement Parts

The emission control systems are designed and certified to work to-
gether in reducing emissions to
levels that comply with the Clean Air
Act. To make sure the emissions remain low, you should use only newGenuine Honda replacement parts or
their equivalent for repairs. Using
lower quality parts may increase the emissions from your car.
The emissions control systems are covered by warranties separate from
the rest of your car. Read your
warranty manual for more informa-
tion.
