How to Replace a 1993 Buick Century Fuel Pump

The Buick Century is a mid-size car manufactured by the Buick division of General Motors. The 1993 model belongs to the fifth generation of the Century, produced from 1982 to 1996. The engine in a 1993 Buick Century may be a four-cylinder 2.2L engine or a six-cylinder 3.3L engine. Both of these engines use fuel injection, requiring a high-pressure fuel pump. The fuel pump in the 1993 Buick Century attaches to the fuel tank, which you must remove in order to replace the fuel pump.

Instructions

    1

    Loosen the filler cap of the fuel tank and raise the the vehicle on jack stands. Disconnect the electrical connector from the fuel pump and lower the vehicle. Start the engine and allow it to run until the engine stalls. Crank the engine for three seconds to consume any remaining fuel in the fuel lines.

    2

    Disconnect the cable for the negative battery terminal with a socket wrench. Raise the vehicle on jack stands and drain the fuel tank. Detach the electrical wiring from the fuel tank, including the ground wire under the body of the vehicle. Disconnect the fuel lines from the fuel tank. Support the fuel tank with a jack stand and remove the nuts on the fuel tanks retaining strap with a socket wrench. Lower the fuel tank with the jack stand and remove it from the vehicle.

    3

    Disconnect the fuel filter from the fuel pump by twisting it and pulling it off the fuel pump. Discard the fuel filter. Detach the electrical connector for the fuel sending unit and remove the fuel sending unit from the fuel tank. Pull the fuel pump from its mounting bracket on the fuel sending unit.

    4

    Install the new fuel pump onto the fuel sender assembly between the mounting bracket and the pulsator. Connect the electrical connector for the fuel sender assembly. Place the fuel filter into position on the fuel pump and push the fuel filter until it is fully seated.

    5

    Install the fuel sending unit onto the fuel tank and connect the fuel tank. Check the fuel system for leaks and connect the battery cable to the negative terminal of the battery with a socket wrench.

How to Troubleshoot a 95 Buick Century

The 1995 Buick Century was available in Special, Custom and Limited editions, each equipped with front-wheel drive and an automatic transmission. Regardless of the type of Century you own, problems can occur during ownership such as overheating, power steering going out and issues with tires and brakes. You can troubleshoot your vehicle to find the problem and save you a lot of money.

Instructions

    1

    Open the hood of the car while the engine is running and listen for the sound of the fan(s) running. This is an indication of the engine overheating.

    2

    Turn the engine off and check the fluid level in your coolant. Wait until the car cools down as it is easy to burn yourself when checking fluid levels of a hot engine. If the coolant is low, refill to the "Full Hot" coolant line. If you notice the fluid leaking, this can indicate a possible leak in your radiator hoses, heater hoses, water pump or another part of the cooling system.

    3

    Remove the dipstick from the power steering compartment while the engine is off. The power steering compartment is located on the passenger side of the engine. Wipe the dipstick with a clean rag and reinsert. If the fluid level is below the "C" mark you may experience difficulty with the power steering. Add fluid and recheck to verify you have added the right amount.

    4

    Inspect your tires to see if there are any bulges, cracks or splits in the tire. Check the treadwear of your tires to determine if you need to replace them. Poor tire conditions can lead to flat tires. Also, the cord or fabric inside the tire should not be showing through the rubber.

    5

    Listen for a high-pitched sound while driving and whether it stops when you press on the brakes. This may be an indication that your brake pads are worn. Unless you are skilled in brake repair, take your car to a repair shop for inspection and possible brake replacement. It is a good idea to have your front and rear brakes checked at the same time.

How do I Replace the BCM on a 1997 Buick Century

The Buick division of General Motors has manufactured a variety of cars under the Century nameplate. The 1997 model is a mid-size sedan with an anti-lock braking system, or ABS. The brake control module, or BCM, controls the ABS in an emergency stop. The BCM detects when a wheel is rotating significantly more slowly than the others, which can occur when the wheel loses traction. The BMC then reduces the braking force to that wheel to prevent it from locking.

Instructions

    1

    Find the BCM on the left side of the steering column under the instrument panel. It is a small black box with an electrical wiring harness connected to it.

    2

    Squeeze the pressure tabs on the BCM together, then detach the BCM from its bracket.

    3

    Unplug the electrical wiring harness from the BCM, then remove the BCM from the vehicle.

    4

    Plug the electrical wiring harness into the new BCM. The electrical connector will make an audible click when the harness is securely fastened to the BCM.

    5

    Install the BCM to its bracket. The pressure tabs will make an audible click when the BCM is securely fastened to the bracket.
