1997 PONTIAC PONTIAC fuel pump

Fuel Gage Low Fuel Light
Your fuel gage tells you
about how much fuel you
have left when the ignition
is on. When the indicator
nears
EMPTY (E), you still
have a little fuel left, but
you should get more soon.
Here are some things owners ask about. All these
situations are normal and do not show a problem with
your fuel gage:
At the service station, the pump shuts off before the
gage reads
FULL (F).
It takes a little more or less fuel to fill up than the gage
indicated. For example, the gage may have indicated
the
tank was half full, but it actually took a little more
or less than half the
tank’s capacity to fill it.
The gage moves a little when you turn a corner or
speed up. The gage needle should move no more
than
1/8 of a tank under any driving maneuver.
LOW
FUEL
If your fuel is low, a light
will come on and stay on
until you add fuel. It will
also come
on for a few
seconds when you first turn
on the ignition as a check to
show you it’s working. If it
doesn’t come on then, see
your dealer.

Before closing the hood, be sure all the filler caps
are on properly. Then just pull the hood down and
close
it firmly.
3800 Supercharged Engine
(If Equipped)
Your Pontiac may have a 3800 Supercharged engine.
The supercharger is a device which is designed to pump
more air into the engine than it would normally
use.
This air mixed with fuel, creates increased engine
power. Since the supercharger is a pump and is driven
from an engine accessory drive belt, increased pressure
is available at all driving conditions.
The powertrain control module (PCM) works with a
vacuum control to regulate the increased pressure
required during specific driving conditions. When this
increased pressure or
boost is not desired, such as during
idling
and light throttle cruising, the excess air that the
supercharger is pumping is routed through
a bypass.
All
of these controls, working together provide high
performance character and fuel efficiency in the
3800 Supercharged engine.
Engine Oil
LOW OIL
LEVEL
If the LOW OIL LEVEL
light on the instrument
panel comes
on, it means
you need to check your
engine oil level right away.
For more information, see
“Low Oil Level Light” in
the Index. You should
check your engine
oil
level regularly; this is an
added reminder.
It’s a good idea to check your engine oil every time you
get fuel, In order to get an accurate reading, the
oil must
be warm and the vehicle must be on level ground.
