1994 PONTIAC BONNEVILLE check engine

Features & Controls
Your vehicle is equipped with the
PASS-Key’II (Personalized Automotive
Security System) theft deterrent system.
PASS-Key’II is a passive theft deterrent
system. This means you don’t have to do
anything different to arm or disarm the
system. It works when you insert or
remove the key from the ignition.
PASS-Key@II uses a resistor pellet
in the
ignition key that matches a decoder
in
your vehicle. When
the PASS-Key@II system senses
that someone is using the wrong key,
it
shuts down the vehicle’s starter and fuel
systems. For about three minutes, the
starter won’t work and
fuel won’t go to
the engine. If someone tries to start your
vehicle again or uses another key during
this time, the vehicle will not start. This
discourages someone from randomly
trying different keys with different
resistor pellets in an attempt to make a
match.
7 SECURITY
The ignition key must be clean and dry
before it’s inserted in the ignition or the
engine may not start. If the engine does
not start and the “SECURITY” light is on,
the key may be dirty or wet. Turn the
ignition off.
Clean and dry the key. Wait about three
minutes and try again. The security tight
may remain on during this time. If the
starter still won’t work, and the key
ippears to be clean and dry, wait about
:hree minutes and try another ignition key.
4t this time, you may also want to check
the fuse (see “Fuses
& Circuit Breakers”
in the Index). If the starter won’t work
with the other key, your vehicle needs
service. If your vehicle

Starting Your Engine
(CONK)
To start your 3.8 Liter engine:
1. Without pushing the accelerator pedal,
turn your ignition
key to “Start”.
When the engine starts,
let go of the
key. The idle speed will go down as
your engine gets warm.
NOTICE:
Holding your key in “Start” for
longer than
15 seconds at a time will
cause your battery
to be drained
much sooner. And the excessive
heat can damage your starter motor.
2. If it doesn’t start right away, hold
your key
in “Start” for about
three to five seconds at a time until
your engine starts. Wait about
15 seconds between each try to help
avoid draining your battery.
3. If your engine still won’t start (or
starts but then stops),
it could be
flooded with
too much gasoline. Try
pushing your accelerator pedal all the
,.a54
way to the floor and holding it there a
you hold the key in “Start” for about
three seconds.
If the vehicle starts
briefly but then stops again, do the
same thing, but this time keep the
pedal down for five or six seconds.
This clears the extra gasoline from
the engine. After waiting about
15 seconds, repeat the normal startin8
procedure.
NOTICE:
Your engine is designed to work
with the electronics
in your vehicle.
If you add electrical parts or
accessories, you could change the
way the fuel injection system
operates. Before adding electrical
equipment, check with your dealer. If you don’t, your engine might not
perform properly.
If you ever have to have your
vehicle towed, see the part of this
manual that tells how
to do it
without damaging your vehicle. See
“Towing Your Pontiac”
in the
Index.
