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.

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.

Anyone have a 1995 Buick lesabre custom, ignition wiring diagram?


Insofar as your Ignition Wiring Diagram, I hope you're speaking of what's also called the Spark Plug Cables or Firing Order. The proper Firing order for your V-6 is 1-5-3-6-2-4 with the number 1 cylinder being the front spark plug on the left hand side. The left hand side is Odd numbered and the Right hand side is Even numbered, therefore number 2 cylinder is the 1st plug on the right hand side of the engine.
