Firing order 94 buick lesabre .... I dont think the numbers are right on the coils

153624 is possibly the firing order but the numbering of the cylinders ? never seen one so i wouldnt know sorry their out engines here in europe only use 4 cylinders and the newer ones 3 cylinders try 143625 if the first firing order doesnt work ,i would expect no 1 to the front left but i just dont know i could work it out with head under the bonnet and follow the rockers working out the timing but offhand no idea

front plug firing order is 135 back is 246 the coils are numbered

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.

For the 1994 Buick LeSabre 3.8L V6:

Firing Order:
1-6-5-4-3-2

Cylinders:
......(back)......
|...2....4....6...|
|...................|
