Question about 2002 Buick LeSabre

1 Answer

I have a 2002 Buick Lesabre. It was running great. I was low on fuel and now it will run smooth, then cut out, stall and even quit. I have to lightly pump the gas to get going again. The check engine light is now on. It acts like it is starving for gas.

2002 buick lesabre 3800 starts but then stalls


William, Check for trouble codes to aide diagnosing, could your security light be on, try your spare key as the chip may be bad in the one you are trying to use. Possible MAF(Mass Air Flow Sensor) faulty, try unplugging and start. Check the attached links,instruction and guides, Good luck

2000 LeSabre starts but runs very rough and stalls. After


Sounds like the plugs are not firing hot enough on initial start-up. Try a quick spark plug change, and clean throttle body. The gas being injected, isn't being burned fast enough by the plugs, which causes the car to have a hard start-up. You may try a higher octane gas or Lucas injector cleaner with your usual octane rating. Lucas comes in a very small bottle, and works very well in my opinion.

Sounds like low fuel pressure. i.e. fuel pump, fuel pressure regulator, or fuel filter.

1999 buick lasabre hesitation while driving.


there are really only 2 things that cause this problem most of the time i have seen it, 1st a defective Mass Airflow Sensor, the second is low fuel pressure from a failing pump or obstructed fuel filter do u have a check/service engine soon light on at any time? have u had the system tested for trouble code's? Go to any Kragen or Autozone and ask for a OBD 2 trouble code test, it is free, record any code's that show and post them back here on this same thread.
