check the entire electrical system. Coil packs (i had one go bad on mine), the plate they mount to, spark plugs, plug wires, alternator, ground straps, everything.
A faulty crank sensor can do that.
Replace the spark plugs and wires. Replace the fuel filter.
Like most cars with no "spark" it can be caused by faulty/old cables. Replacing them would be a quick and cheap solution if in fact they are the cause.
It could be the spark plug wires that's what was wrong with mine.
The spark plug gap for a 2003 Buick LeSabre should be set at .060 inches. The best spark plug for this vehicle would be an Iridium plug.
I found this site looking for a similar problem for a 96. http://www.taurusclub.com/forum/lofiversion/index.php/t57249.html
If it's a 6 cylinder , 6 , if 8 cylinder , which I think Buick does not make in that model , it would be 8 .
what will cause a transmission in a 1992 buick lasebre to shrudderas and stall engine
No spark would usually be the ignition coil.
Replace your transmission pump or get a new transmission.
bad spark plug wire.
