    Why does my car keep cutting off when the service engine soon light comes on.
    the vehicle has 60,000 miles on it. It cuts off after the engine gets warm and will start after 30 minutes of sitting but will stall after 50 feet of moving. Diagnostic code is P0128. I just notice that the gas is very low (60 mile left before running out of ...

      The P0128 fault code indicates that the thermostat is stuck open causing the engine to run too cold at all times, however, this is NOT the cause of your stalling. The cause of your stalling is *probably* a bad crankshaft position sensor even though there is no code for that.

      Please detail this clicking sound further. "clicking sound" is insufficient and does not allow me to conjure up anything. One single click? Repeated clicking? Origin of this clicking? What works or doesn't work when trying to start it at night? Lights etc? Did you try to jump start it? details....

      It needs a bettary is a greater than 90% probability. A battery terminal that is loaded with white or green corrosion is a 10% probability.

    Why would my engine die and than restart for 30 secs and die again?
    Its a 2000 Buick Lesabre custom with new radiator, heater core, headgaskets, fuel fitler ( all newly replaced 4 days ago... When I drove the car the first time the cars engine shut off while driving, It would start for 30 secounds and then die. It sounded like it ...

      Please explain in further detail about this clicking that you have now. I want to know that if you jump the battery that the engine will crank. I need to know what you mean when you say the engine just clicks now. I am at a crossroads here and need to know the answer to that first.

      The clicking noise is like the clicking noise you hear when you have a bad starter

      What about jumping the battery?

      I was told it was the coil pack, but dont know what one
      HouseCallAuto
      11/10/2013 HouseCallAuto
      If the engine clicks when you try to start it now, the cause of that is not a coil pack. That is why I keep asking you have you tried to start the engine with a jump? Yes / No ? I have a specific reason for asking.

      there is insufficient detail here. "Won't start" has two meanings.

    Engine won,t start, engine cranks but back fires when cranking.
    was running fine then just would not start no more. power modual was replaced already because thought that was the problem. Car has only 60,000 miles on it !

    The car is overheated
    it seems that the cooling fans on the radiator are not working

      The check engine doesn't have to be on to store a fault code..
      Using an obd2 code reader Autel MaxiScan MS300 CAN Diagnostic Scan Tool for OBDII Vehicles to read the fault codes.The price is $ 15.69 dollars + shipping @ amazon.com.

      1. Using a 12 volts direct to test the radiator fan.If the fan is Ok, next.

      2. Test the engine coolant temperature ( ect ) sensor.
      Sensor Installed in Vehicle
      Disconnect the engine wiring harness from the ECT sensor.
      Connect an ohmmeter between the ECT sensor terminals.
      With the engine cold and the ignition switch in the OFF position, measure and note the ECT sensor resistance.
      Connect the engine wiring harness to the sensor.
      Start the engine and allow the engine to reach normal operating temperature.
      Once the engine has reached normal operating temperature, turn the engine OFF .
      Once again, disconnect the engine wiring harness from the ECT sensor.
      Measure and note the ECT sensor resistance with the engine hot.
      Compare the cold and hot ECT sensor resistance measurements with the accompanying chart.
      If readings do not approximate those in the chart, the sensor may be faulty.
      See the chart @ www.autozone.com

      Note: Temperature sending unit sends a signal to the temperature gauge on the instrument panel
      When not replaced, vehicle may experience inaccurate temperature gauge function, overheating engine, internal engine damage and/or excessive fuel consumption.

    The car is running hot and when I check the oil it looks like its is mixed with water

      Probably a bad head gasket. Does the coolant look clean or does it look like there is oil in it as well?

      I would have the charging system checked. Most part stores like AutoZone will check it for free.

      This does sound like a charging system issue. Have to check the system while the dimming is going on.

      Try running the car with the gas cap removed. Are you saying that when you try to fill your gas tank it will not take fuel. This sounds like the fuel tank vent valve is stuck or the evap vapor line is plugged or pinched. This will cause fuel tank filling issues and will make your engine starve for fuel. You will most likely have to drop the fuel tank again to check the vapor line. If you have a vacuum pump you could apply vacuum to the tank vapor line at the EVAP canister. If it holds vac. pressure then you know that the line is plugged or pinched or the valve is stuck. The vent valve is often damaged when removing or replacing the fuel tank.

      1.Did the fuel filter was changed ? The filter might clog up .

      2.Check the FUEL SYSTEM PRESSURE
      1999 Buick Lesabre 3.8L SFI OHV 6cyl
      The Fuel System Pressure

      48-55 PSI (Pounds per Square Inch)Position the ignition switch and the A/C system in the off position. Install a fuel pressure gauge to the vehicles fuel rail or fuel pressure test port.Confirm that no leaks are present, and visually verify the PSI reading on the gauge with the ignition in the on position.
