What is the firing order for a 1986 buick regal 305 engine


The firing order is the same, 18436572
But, depending on who made the engine, the firing order may go cw or ccw around the cap. You need to check which way the rotor turns when you crank it, then follow the firing order in that direction. Sometimes the number 1 spark plug tower is marked on the cap, if not, put the number one cylinder on top dead center of compression stroke, which ever coil tower the rotor is leading into is number one, then follow the firing order in correct direction of rotation. You driver side cylinder bank should be numbered, 1357 from front to back, passenger side 2468, front to back.
If you replace plugs and plug wires, one at a time, you won't have this problem. Goodluck.
