2005 Buick LesabreBeen told I have a bad fuel pump but don’t believe that’s the problem. Cause it pumps gas out for a few seconds and stops when I take the filter line off. but was told by the auto zone guy that the pump is bad if it stops pumping.

I believe maybe for a old car but mine probably has a sensor to tell it to stop pumping need a real mechanic to verify this thank you, car run hot and shut off was a burning smell but it didn’t lock up still turns over but won’t crank replaced crank sensor, cam sensor, checked the timing chain, and replaced the control module because the same auto zone guy tested it and said it was bad but didn’t fix the car. So think he’s just don’t know what he’s talking about or trying to sell parts. Also it’s getting fire thank you for any help.


When the car is turned on the fuel pump is activated for only a few seconds and then it no longer sent power. This is unless the ignition key is placed in the “START” position.

Generally the fuel pump can be tested by the amount of fuel pressure it builds. Therefore using a fuel pressure gauge to test is best. If you are certain your engine has spark then you could spray some starting fluid in the air filter to see if it wants to start. This would let you know that it is a lack of fuel if it tries to start.

Relieving Fuel Pressure Caution

Warning! Remove the fuel tank cap and relieve the fuel system pressure before servicing the fuel system in order to reduce the risk of personal injury. After you relieve the fuel system pressure, a small amount of fuel may be released when servicing the fuel lines, the fuel injection pump, or the connections.In order to reduce the risk of personal injury, cover the fuel system components with a shop towel before disconnection. This will catch any fuel that may leak out. Place the towel in an approved container when the disconnection is complete.

Buick Park AvenueMy left turn signal is working perfectly but right isn’t


Do you see the light on the dash blinking a bit faster on the right as compared to the left? If the answer is YES, than most likely one of the bulbs is blown on the right side. Replacing the blown bulb will correct this.

Possible Causes

  • Wrong bulb
  • Loose connection at bulb
  • Bad connection in wiring
  • Rusted ground connection
  • Wiring issue
  • Worn multi-function switch

Buick Lacrosse Starting Disabledmotor stops running an says starting disabled, wait 2 min. and then it will restart


Starting Disabled

Generally the dash will display ” Starting Disabled” when the anti-theft has been activated. Since your engine is already running and then dies I wouldn’t think it is anti-theft related. Sometimes after a battery has been changed or a vehicles battery has been jumped a relearn procedure needs to be performed. Research shows in most cases the issue has turned out to be related to a failing crank sensor.

Security Relearn

  1. With a master PASS-Key III key, turn ON the ignition, with the engine OFF.
  2. Observe the STARTING DISABLED DUE TO THEFT message on the driver information center (DIC), after approximately 10 minutes the STARTING DISABLED DUE TO THEFT message on the DIC will turn off.
  3. Turn OFF the ignition, and wait 5 seconds .
  4. Repeat steps 1-3 two more times for a total of 3 cycles or 30 minutes .
  5. With a master PASS-Key III key, start the vehicle. The vehicle has now learned the key transponder information and the PCM has now learned the fuel continue password. IMPORTANT: The vehicle learns the key transponder information and/or passwords on the ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.

Buick LesabreMy 2000 Buick LeSabre Limited is at the 190k mark. I change my oil religiously but have only had the car six years. I am on top of the brakes and suspension. But I am 60 years old and don’t want to invest in another car. What do I need to do to keep this thing on the road as long as possible? What more can I anticipate needing repair imminently. TY


4 Ways to make your Buick last longer

Proper Maintenance

It can be difficult to anticipate car problems. Following the scheduled maintenance listed in the car owners manual is a good place to start. You can inspect your car every time you enter it, or on a daily or weekly basis or at intervals specified in the manual. Typically Buick is a top of the line quality vehicle. Although age and weather have a certain effect on just about all vehicles. If you drive in snowy conditions wear road salt is used you can anticipate parts rusting out. Some of these parts can be brake lines, mounts and exhaust, etc.

Fluid Levels

Its great that you understand the importance of keeping up with your vehicle. Changing the oil is wonderful. However checking the oil level and keeping it at the proper level is equally important. You may not need to check the level everyday but doing so frequently to determine how often you will need to add some oil is important.

Battery and Tires

The battery typically lasts about 4 years so anytime after that is a bonus. Tires wear and are one of the most important parts of the car. They assist in stopping, traction and steering. Rotate them about every 7 thousand miles and replace when the tread is less than 3/32 of an inch.

Smells and Noises

Anything out of the ordinary is an indicator that something may be wearing out. Just paying attention to any changes when driving the car is key. If you notice something, get it checked out. It is better safe than sorry.

These 4 ways to make your Buick last longer should help even the most novice car enthusiast.

1995 Buick Century

Electrical Problem

Had to drive in snowstorm other night, before snowplows were out for about 1/2 hour and about 2 blocks before I got home just driving down the road normally my headlights went out. Then I noticed because I continued on the hazards didn’t work. Looking behind I could tell tail lights were out and brake lights to. So started checking other things. Car was running fine and I got home and out of habit put on the turn signal to turn in driveway and it worked. So tried other side and it worked.

What Doesn’t Work

OK, now here’s everything electrical that went out. All I’ve mentioned so far plus rear defroster, power door locks, dome light and interior lights, gauge lights, horn, and it has a light under hood when you open it that was out(power windows still worked). Also I have 2 little blue led lights plugged into cigar lighter they were out. Everything else worked, Like the wipers, heater, windshield defroster Turn signals and like I said, car was running fine and normal and still is. Fuses all good! Now for even stranger part I come outside about an hour later and noticed those little blue led lights plugged in cigar lighter were back on. So I’m thinking alright, everything’s back on. So jump in and hit the headlights, hear a click and they did not come on. Little blue lights went out again and everything that didn’t before was back to not working again. Checked fuses and again were all fine. This is strangest electrical problem I’ve ever had! What it there something shorting out before going through fuse box or maybe headlight switch or, Oh and why do do turn signals work but not hazards??

Maybe I need a priest? Please help, I hate driving only when the sun is out…thank you.


I would look at a loose or corroded connection at the battery. Quite common for an older vehicle such as this. No short or the fuses would be blown. You are loosing a connection that provides power to a lot of things. So either the negative or positive battery cable connections or cables are dirty/corroded or loose.

2005 Buick LesabreMy car suddenly made a high pitched squealing noise while moving. It felt like it was coming from steering wheel area But eventually grew to metal grinding noise sort of metal on metal then grinding gear like fly wheelish… Car has had lots of work, transmission is warranted – not labor, crv?

Don’t know need some ideas so I can take it to warranty place or ignore it, brakes have 13k on it and no chirping ever heard or. Felt


Metal Grinding Noise

The first place to look for a metal on metal noise would be the brakes. This is the most common place for a metal on metal noise. It is normal for brakes to make a squealing noise before it turns into a metal grinding noise when there is a brake related issue. It is possible that you have a sticking brake caliper that has caused premature wear of the brake pads.

1998 Buick CenturyHow do I re-install the pulley on the harmonic balancer?


First of all on this engine the pulley is part of the balancer. They are meant to be one unit. There is a rubber insert between the pulley and the outside of the balancer. As a result there is no way to re-install the outside pulley once it comes apart as it is a balanced unit. In conclusion a new replacement should be used if damage is found on the harmonic balancer.

Replace Harmonic Balancer


 The inertial weight section of the crankshaft balancer is assembled to the hub with a rubber type material. Therefore the correct installation procedures (with the proper tool) must be followed or movement of the inertial weight section of the hub will destroy the tuning of the crankshaft balancer.

  • Remove the drive belt.
  • Raise and suitably support the vehicle.
  • Remove the right front tire and wheel.
  • Take off the right engine splash shield.
  • Remove the crankshaft balancer bolt and the washer.
  • Remove the crankshaft balancer. Use a Balancer Puller.

harmonic balancer removal 1998 Buick Century


    1. Apply sealant to the keyway of the balancer, this is especially relevant. Use sealant GM P/N 12345739 or equivalent.
    2. Install the crankshaft balancer. Use the J 29113/66515 .

    1. Remove the J 29112/66515.

harmonic balancer installation 1998 Buick CenturyCaution!First of all use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. In addition the fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener too. Most of all use the correct tightening sequence and specifications while installing fasteners in order to avoid damage to parts and systems.

  • Install the crankshaft balancer washer and the bolt.

Tighten the crankshaft balancer bolt to 103 N·m (76 lb ft).

  • Install the right engine splash shield.
  • Install the right front tire and wheel.
  • Lower the vehicle.
  • Install the drive belt. Refer to Drive Belt Replacement.
