1994 BUICK CENTURY fuel pump

dangerous. So please get to know your warning lights
and gages. They’re a big help.
Fuel Gage
I
Your fuel gage tells
you about how much
fuel you have left,
when
the ignition is on.
When the indicator
nears
“E” (Empty), you
still have a little fuel
left, but you should get
more soon. Here
are four things that some owners ask about. None
of these show a problem with your fuel gage and are
normal operating characteristics:
0
0
0
0
At the service station, the gas pump shuts off before
the gage reads
“F” (Full).
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
the tank.
The gage moves a little when you
turn a corner,
speed up or brake.
The gage doesn’t go back to
“E” when you turn off
the ignition.

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher. It should meet specifications ASTM
D4814 in
the U.S. 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
U.S. 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 knocking, 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.

Look at the silver-colored band inside the fuse. If the
band is broken or melted, replace the fuse. Be sure you
replace a bad fuse with a new one of the identical size
and rating.
Headlights
The headlight wiring is protected by a circuit breaker in
the light switch. An electrical overload will cause the
lights
to go on and off or, in some cases, to remain off. If
this happens, have your headlight system checked right
away.
Windshield Wipers
The windshield wiper motor is protected by a circuit
breaker and a fuse.
If the motor overheats due to heavy snow, etc.,
the wiper will stop until the motor cools.
If
the overload is caused by some electrical problem, have
it fixed.
Power Windows and Other Window
Options
Circuit breakers in the fuse panel protect the power
windows and other power accessories. When the current
load is too heavy, the circuit breaker opens and closes,
protecting
the circuit until the problem is fixed.
Cigarette Lighter Fuse and Safety Belt Fuse
These fuses are located behind the glove box. The fuse
holders are taped together with gray tape.
Other Fuses
The Safety Belt/Chime (ICAM) Module fuse and the
Remote Lock Control fuse are located behind the fuse
block, above the hush panel.
The Fuel Pump and
ECM fuses are located under the
hood.
