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

SOURCE: 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.

SOURCE: 1990 Buick Lesabre keeps stalling

Check ecm for part number 1228253. If it has this number in it replace it with a 16198264. Gm had trouble with that ecm for a cutting off problem. Mine would stall driving down the road and when I would put it neutral it would start back up and not have any trouble for the rest of the day. You must set the tps with a volt meter or scan tool.

I need a spark plug wiring diagram for a 1997 Buick LeSabre


Pick the one below that matches your coil pack orientation. There should also be cylinder numbers on your coil pack.

I have a 1990 buick lasabre and not getting any fire to my spark plugs. there is no fire to the plug wires at the coil pack. i've got a knew coil pack, module, and crank shaft sensor and still no fire. can...


If those three items are replaced and it still doesn't fire up, look for a possible computer problem.
Or, look for a broken wire or fuse for the ignition system.

Good luck on this repair.

I need the firing order diagram of a 1990 Buick LeSabre? I also need to see a diagram of what wire goes to what plug? Replacing ignition coil and module ?


I would ask a buick car dealer. Someone in the service dept should know. Maybe one day you could just drop by there, go to the service dept and ask the guy at the service desk. He can pull out a service manual and in about two min. tell you everything.
