Coil pack check, get a pair of insulated pliers pull one plug wire
at the coil while vehicle is at idle. you will see spark, if not the coil is bad. coils are sold individually, there is three coils one for every two
cylinders.

You can take them off and have them tested or you can pull the plugs and there should be two plugs that will be really black follow those wires back to the coil that is bad. or you could also have someone crank it while you stick a screwdriver in the end of the wire on the plug and hold the screwdriver next to the engine or a good ground and there should be a bright blue spark but be careful and dont touch the car or it might tickle a little bit

SOURCE: 1998 Buick Lesabre How do you test the coil packs?

the coils are one integrated block with 3 separate segments. the coil pack is mounted to the ignition module and can be unbolted from each other. one can test the coils from the underside of the coilpack with a dvom. having said that your car should still start if one paired coil fails, it would however miss on one or two cylinders. I would suggest to scan for codes, monitor live sensor data to see if you have a valid crank signal, check fuel pressure and spark voltage

1998 BUICK LESABRE CUTS OFF WHILE DRIVING


The problem is the crankshaft sensor for sure. It is mounted behind the crankshaft pulley which is pretty difficult to get off as you need a special puller. A shop should charge about 1.5 hours for this job. It is a very common problem.
