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.

When 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.

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 instrument panel

to blink rapidly (see page

).

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 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

.

Turn the ignition switch to the

START (III) position. If the

headlights do not dim, check the

condition of the fuses. If the fuses

are OK, there is probably

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

.
