The firing order for all years of Chevrolet Celebrity V6's is: 1-2-3-4- 5-6
Firing is 1-3-4-2 on a 1986 celb with the 2.5L 4 Pontiac Iron Duke. The order is found on the intake manifold.
The firing order on a Chevy Celebrity depends on which engine your car has. If it is the 2.5L 4 cylinder engine the firing order is: 1-3-4-2 If it is the 2.8L V6 the firing order is: 1-2-3-4-5-6

When facing the engine the # 1,3 and 5 are at the firewall or back of the engine going from left to right and the # 2,4 and 6 are on the front going from left to right. the firing order is 1,2,3,4,5,6 going clockwise. when you are facing the engine from the front the # 1 plug wire is at the 11 o'clock position on the distributor cap

On the 2.8L V6 the distributor cap is held on with two screws. Unscrew the two screws and pull straight up on the distributor cap to remove it from the distributor.
The firing order for a 2.0 L. is 1423.
I found one source that says a 1986 Chevy Celebrity has a curb weight of 2714 pounds. Different options would change that weight.
