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, 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 tostart. 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 297.
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 ignitionswitch or starter motor. You will
need a qualified technician to determine the problem. (See

Emergency Towing on page 311.)
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 251). You can then try jump starting the vehicle
from a booster battery (see page 297).
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 starting
procedure? Refer to Starting the
Engine on page 197.

If Your Engine Won't Start, Jump Starting
Your vehicle has the Immobilizer
System. You should use a
properly-coded master or valet key
to start the engine (see page 77).
A key that is not properly coded
will cause the immobilizer system indicator in the dash panel to blink
rapidly. 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 305).
If you find nothing wrong, you will
need a qualified technician to find
the problem. See Emergency
Towing on page 311. Jump Starting
If your vehicle'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 vehicle, follow
these directions closely:
1. Open the hood and check the physical condition of the battery(see page 251). 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.

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

Low Oil Pressure Indicator

This indicator should light when the ignition switch 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 offthe engine as soon as you can safely get
the vehicle stopped.

1. Safely pull off the road and shut off the engine. Turn on the hazard
warning indicators.
2. Let the vehicle sit for a minute. Open the hood and check the oil
level (see page 186). Although oil
level and oil pressure are not directly connected, an engine that
is very low on oil can lose pressureduring cornering and other driving

maneuvers.

3. If necessary, add oil to bring the level back to the full mark on thedipstick (see page 233). 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 Emergency
Towing on page 311.)

Charging System Indicator

This indicator should come on when the ignition switch is ON (II), and goout 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,
climate control, 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 tostall it. Starting the engine will
discharge the battery rapidly. By eliminating as much of the
electrical load as possible, you can
drive several miles (kilometers)
before the battery is too 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
vehicle's performance, it can reduce
your fuel economy and cause your
vehicle 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 at least
three times. Replace the 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 threedriving 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
malfunction indicator lamp on. you can
damage your vehicle's emissionscontrols and engine. Those repairs may
not be covered by your vehicle's
warranties.

This indicator may also come on along with the "D 4
" indicator.

Brake System Indicator

BRAKE SYSTEM INDICATOR*

The Brake System Indicator light comes on when you turn the ignitionON (II). If the parking brake is not
set, it goes off after you start the
engine. If the parking brake is set, it
goes off when you fully release the
parking brake with the engine
running.
If it comes on at any other time, it
indicates a problem with the vehicle's
brake system. In most cases, the
problem is a low fluid level in the
brake fluid reservoir. Press lightly on
the brake pedal to see if it feels
normal. If it does, check the brake
fluid level the next time you stop at a service station (see page 244 ). If the
fluid level is low, take the vehicle to
your dealer and have the brake system inspected for leaks or worn
brake pads.
However, if the brake pedal does not
feel normal, you should take immediate action. Because of the
brake system's dual-circuit design, a
problem in one part of the system
will still give you braking at two
wheels. You will feel the brake pedal go down much farther before the
vehicle begins to slow down, and you
will have to press harder on the pedal. The distance needed to stop
will be much longer. Slow down by shifting to a lower
gear, and pull to the side of the road
when it is safe. Because of the
longer distance needed to stop, it is
hazardous to drive the vehicle. You should have it towed, and repaired assoon as possible. (See Emergency
Towing on page 311 .)
If you must drive the vehicle a shortdistance in this condition, drive
slowly and cautiously.
If the ABS indicator and the TCS
indicator (on EX model) come on
with this indicator, have the vehicle inspected by your dealer
immediately.

Fuses

UNDER-HOOD
The primary under-hood fuse box is located in the back of the engine
compartment on the passenger's side.

To open it, push the tabs as shown.
UNDER-HOOD
The secondary fuse box is in the engine compartment next to the
battery.
Checking and Replacing Fuses

If something electrical in your
vehicle stops working, the first thing you should check for is a blown fuse.Determine from the chart on pages 309 and 310, or the diagram on the
fuse box lid (the diagram for the driver's side interior fuse box is on
the kick panel below the fuse box),
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.

Emergency Towing

If you decide to tow your vehicle
with all four wheels on the groud, make sure you use a properly-designed and attached tow bar.
Prepare the vehicle for towing as
described above, and leave the
ignition switch in Accessory (I) so
the steering wheel does not lock. Make sure the radio and any items
plugged into the accessory powersocket are turned off so they do not
run down the battery.
The steering system can be damaged if
the steering wheel is locked. Leave the
ignition switch in Accessory (I), and
make sure the steering wheel turns
freely before you begin towing.
Trying to lift or tow your vehicle by the

bumpers will cause serious damage.
The bumpers are not designed to

support the vehicle's weight.

Emissions Controls

Exhaust Emissions Controls
The exhaust emissions 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
emissions control systems areseparate from the crankcase and
evaporative emissions 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 (CO2), dinitrogen (N 2), and water vapor. Replacement Parts
The emissions 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 new Genuine Honda replacement parts or
their equivalent for repairs. Using
lower quality parts may increase the emissions from your vehicle.
The emissions control systems are covered by warranties separate from
the rest of your vehicle. Read your
warranty manual for more informa- tion.
