1995 PONTIAC FIREBIRD fuel pump

Here are four concerns some owners have had about the
fuel gage. All these situations are normal and do not
indicate that anything is wrong with the
fuel gage.

At the gas station, the gas pump shuts off before the
gage reads
FULL (F).
It takes more (or less) gas to fill up than the gage
reads. For example, the
gage reads 1/2 full, but it
took more (or less) than half
of the tank’s capacity to
fill it.
The gage moves a little whefi you turn, stop or speed
UP.
When
you turn the engine off, the gage doesn’t go
back to EMPTY (E).
Convertible Top
The following procedures explain the proper operation
of your convertible top.
To Lower Your Convertible Top
NOTICE:
Don’t leave your convertible out with the top
down for any long periods of time. The sun and
the rain can damage your seat material and other
things inside your car.
1. Park on a level surface. Set the parking brake firmly,
shift an automatic transmission into
PARK (P) or a
manual transmission into
REVERSE (R). The
ignition must be in the ACC or
RUN position. Lower
both
sun visors.

3.4L L32 (Code S) and 3.8L L36 (Code K)
The 8th digit of your vehicle identification number
(VIN) shows the code letter for your engine. You will
find the VIN at the top left of your instrument panel.
(See “Vehicle Identification Number” in the Index.)
Use regular unleaded gasoline rated at 87 octane or
higher.
It should meet specifications ASTM D4814 in
the United States and CGSB
3.5-92 in Canada. These
fuels should have the proper additives,
so you should not
have to add anything to the fuel.
In the United States and Canada, it’s easy to be sure you
get the right kind of gasoline (unleaded). You’ll see
UNLEADED right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler neck.
Be sure the posted octane is at least 87. If the octane is
less than 87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
still hear heavy knockmg, your engine needs service.
But don’t
worry if you hear a little pinging noise when
you’re accelerating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.
What about gasoline with blending materials that
contain oxygen (oxygenates), such as MTBE
or alcohol?
MTBE is “methyl tertiary-butyl ether.” Fuel that is no
more than 15% MTBE is fine for your vehicle.
Ethanol is ethyl or grain alcohol. Properly-blended fuel
that is no more than
10% ethanol is fine for your
vehicle.
Methanol is methyl or wood alcohol.
NOTICE:
Fuel that is more than 5% methanol is bad for
your vehicle. Don’t use it. It can corrode metal
parts in your fuel system and also damage plastic and rubber parts. That damage wouldn’t
be
covered under your warranty. And even at 5% or
less, there must be “cosolvents” and corrosion
preventers in this fuel to help avoid these problems.

5.7L LT1 (Code P)
The

(VIN) shows the code letter for your engine. You will

VIN at the top left of your instrument panel.
(See “Vehicle Identification Number” in the Index.)
Use premium unleaded gasoline rated at 91 octane or higher
for best
performance. You my use middle grade or regular
unleaded gasolines, but your vehicle may not accelerate
as
well. The gasoline you use should meet speakations
ASTM D4814 in the United States and CGSB 3.5-92 in
Canada. These fuels should have the proper additives, so
you should not have to add anwg to the fuel.
In the United States and Canada, it’s easy to be sure you
get the right kind
of gasoline (unleaded). You’ll see
UNLEADED right on the pump. And only unleaded
nozzles will
fit into your vehicle’s filler neck.
Be sure the posted octane for premium is at least 91 (at
least
89 for middle grade and 87 for regular). If the octane
is less than
87, you may get a heavy hocking noise when
you drive.
If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 91 octane or higher and you
still hear heavy
knocking, your engine needs service.
