I bought a 2001 Buick Le Sabre Limited back in August and it drove just fine for a couple months. My problem started in mid November when I started having troubles started the car. It would take a couple tries before my car would start. I just figured it was due to the weather getting colder, but then the problem got worse. When I would stop at stoplights my car would start to rumble and shake and then would eventually would just turn off. Then it started turning off while I was driving. It would only happen once in a while but now it happens multiple times a week. It has also gotten harder to start the car. I now have to hit the accelerator while starting it for the car to start.

Me and my dad took it to Tires Plus and they did a tune up on the car which included changing the fuel filter (my dad thought thats what the problem was), The people at TiresPlus drove it around for a while, and they said they had no problems, so I thought the problem was fixed, but it has continued to turn off while driving and especially while stopped at stoplights. Does anybody have an idea what the problem could be? I'd really appreciate it because I don't know much about cars and would like to have an idea about the problem could be before I take it back in.

it could be water in the lines or a bad fuel pump or its just dirty. you could go to the auto zone near you and get some dry gas for the water in the lines. some heat for the frozen water and get some fuel clear that will go through and clean the pumps and the injectors that was what was wong with my car and that help to fix all the stalls.

i agree with ice blue. sounds like a fuel pressure problem. maybe the regulator or sending unit. get the test done or you can buy a pressure tester and do it yourself.

If it's tha problem..it's a easy swap out..just remove tha trunk mat & theres a access panel to tha right next to tha back seat..unbolt that & theres tha top of tha sending unit which tha pump is attached to..

I've been dealing with similar issues with my 93. I think it could be many things. Besides fuel line related problems it could be one of the many sensors, spark plugs, ignition coil... Just go to harbor freight (or local cheap tool store) and get a fuel pressure tester kit. They're real cheap but will probably work well enough for this project IMHO.

The fuel pressure meter needs to be long enough to drive the car with it attached and hope to get it to do it with the gauge duct taped to the outside of the windshield, e.g., to see if the pressure drops.

For the 1993, I'd sure look at the crankshaft position sensor under the edge of the harmonic balancer. There also is a camshaft sensor that loses its little magnet that's glued in. Some have replaced the magnet without taking things completely apart.

For both cars I'd make sure the connections on the plug on the spark control plate under the coils are fresh and clean. I'd take off the coils and check and clean the connections between each coil and the spark plate.

MAP sensor, crank shaft sensor, MAF sensor, fuel pressure etc. are all likely culprits. Bad sensors will leave a trouble code usually. Fuel pressure is where Id start if no codes are present.
