    Paul - 1994 Buick LeSabre - Engine - 3/10/2014
    My car won't start, symptoms listed in additional details. Is the problem likely a starter, battery or solenoid?
    My 1994 Buick LeSabre continually makes fairly rapid clicking sounds when I try to start it but I don't hear the engine turn after a split second and the car doesn't start. I cleaned the battery and cable terminals and correctly ran jumper cables to the battery ...

      Sounds like a weak battery - but before replacing the battery, remove it and take to the nearest auto parts store to have the battery fully recharged and tested for free.

      There may be other issues; alternator, serpentine drive belt worn or belt tensioner worn.

      Once the battery is fully charged and reinstalled - take the vehicle to the nearest auto parts store for a complete charging system test - for free - to test the condition of the; alternator, battery, belt, wiring, starter, etc. Post a reply with the results for further assistance.

      It turned out the old battery was shot. The new battery did the trick, it started right up. Thanks for the help. I will, however, have the charging system tested just to make sure. Thank you!

    Hard Start Cold No Fuel Pressure
    Car only has 29k just purchased...Had all new injectors and fuelpump replaced. When sitting for several hours it has no fuel pressure until cranking for extended period then runs rough for a while

      Replace the fuel injection pressure regulator - this device maintains a certain fuel pressure and evens out the pulsations of the fuel injectors. You also need to test the fuel pressure at the fuel rail - the fuel rail is simply a tube to distribute fuel to each injector at each cylinder.

      The parts are readily available from these many on-line sources, www.partsgeek.com, www.rockauto.com, www.discountautoparts.com, www.autopartswarehouse.com, www.jcwhitney.com - to list only a few possibilities.
      In fact, they (RockAuto) list the fuel injection pressure regulator from around $37.00 for your vehicle.

    Hard start no fuel pressure cold
    Just purchased only has 29k. Had all injectors and fuel pump replaced. Still after sitting for several hours there is no fuel pressure until cranked for extended period then runs rough.

      Did you check gauge imediatly after shutting car off. It should hold pressure and not bleed
      off. If it does you maybe losing pressure because the pressure regulator or an injector is
      bleeding off the pressure

    Check engine light on + rough idling
    what may cause these problems
     
    • Jimm
      2/28/2014 Jimm
      The check engine light is located on the dash and stays on if the computerized engine control system detects an engine performance or emissions problem.

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA, etc. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light. There are literally hundreds of possible fault codes and therefore numerous reasons for the MIL condition.

      This step is important - retrieving the stored fault code and relaying this detail - will provide good information to assist in diagnosing and repairing the issue you are having.

    Is $4000.00 a fare price to install rebuilt engine?
    I got a 1992 Buick Regal Limited coupe with a 3.1L engine. The mechanic looked at the engine after the intake manifold was lifted and said the engine is full of sludge and not worth fixing. So I said replace engine with a rebuilt 3.1 L . The mechanic quoted ...

      A remanufactured engine is about $1500 plus the cost of oil and filters and gaskets etc and will require about 20 hours of labor to dress the new engine and install. $4000 is a good price. Anyone that would do this job is entitled to expect a profit of about 2000 to 2500 for all those hours. In New York you would not get this job done for less than $4500 or more.

      One more thing. If you decide to go ahead with this it would be in your best interests to assemble the engine with 6 new fuel injectors as the fuel injectors GM used between '87 and '93 were prone to failure and I am sure are very degraded by now. Maybe they will let you supply them so they don't mark up those parts. They are making money on the rest of the job so they shouldn't mind. It will not add any labor while the engine is apart anyway. Also, ask about warranty coverage. Typical industry warranty is usually 3 year unlimited mileage.

      buy injectors online. Try to buy new, not remanufactured

      I'm confused. What do you mean when you say " idle is too high only to start "?
      If the idle is high all the time, you may have anything from a vacuum hose leak
      to a bad Idle Air Control Motor

      The stalling problem was likely either a bad crank sensor or a bad ignition module.

      No you just need to take it to another mechanic and tell the same story. Your story is the truth so its easy to understand. The engine in your Buick is not an uncommon engine and most shops will be fine with taking over. I don't know how the stalling out got related to a coolant leak and intake manifold removal but whatever. Tell the same story to another shop. Stop in there in person and tell the story before bringing them the car. Get a feeling of assurance that they will handle it.

      I will do that. I will stop in a triple A approved shop in person , tell them the story then get Buick towed there if they accept .

      I appreciate your advice.

      The only thing that can cause the fuel pump fuse to blow is a direct short circuit internally of the fuel pump motor itself OR if the Gray battery voltage supply wire is touching a ground in between the fuse panel and the fuel pump connector. In most cases the fuel pump is the cause, but this still requires confirming.

    Why does vehicle flood and stall sporadically?
    This vehicle will flood (no pedal depression) while starting and will stall when [pulling into parking lots or other stops. This only happens sporadically but I would guess it to be a fuel control valve or something that mal-functions occasionally. I do not know ...

      How long since a tune-up? It sounds like your having idle issues. I'd check anything that has to do with idle air and air intake. When you go to start, you can hold the throttle open just a little, see if makes any difference?

      With intermittent issues, you need to test when problem is ongoing. Can you check for applicable trouble codes. Some of the national brand auto stores will check codes for free. If there are any?

      Hope you got it fixed by now. Did it run after you installed the new fuel pump? Did you check voltage and ground at the pump when the problem was ongoing?

      You may have a bad ignition switch. Not that uncommon on these vehicles.

      It can cause these issues. However, what you can try is playing with the key (back and forth) to
      see if it causes any difference. Also if it has tilt wheel, you can try the key thing while moving
      the tilt wheel up and down.

      Have you had a chance to do what I suggested? Moving the key slightly back and forth. Not
      that is a definative diagnosis.
    • HouseCallAuto

      I agree with John's and would say that the cause is a bad ignition switch with 100% confidence. Replace it. All these issues are well known symptoms of an intermittent ignition switch on this vehicle.

    Car is leaking oil bad. Looks like it is coming from the front of the motor close to the radiator.
    Too cold and dark to see. What could the problem be!

      There is no substitute for doing a visual look. There is no motor oil that runs near the radiator. So maybe you meant to say transmission oil? Could be a transmission cooling line?
