1998 Buick Lesabre How do you test the coil packs?

I asked earlier if you could set the timing on a Buick Lesabre 1998, and I was told no, because eack one has a coil pack and if one is bad it could prevent the car from starting. How do you check the coil packs? to know which one is bad.

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

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.

Buick Lesabre 1998, How you check the coil packs?


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
