165432 is firing order I believe the #1 is the lower right if you looking from front of truck
Standing in front with the hood open, looking at the distributor, #1 is at the 6 O'clock position, from there clockwise it is 1, 6, 5, 4, 3, 2.
The firing order for a 1996 Chevrolet S10 Blazer is 1, 6, 5, 4, 3, 2. The number one cylinder is on the front right as you face the engine.
1-8-6-5-4-3-7-2- firing order is number 1 should point at number 1 cylinder.than go clockwise from there.

The firing order for a 1991 Mitsubishi Eclipse with a 4-cylinder engine is 1-3-4-2. On the distributor cap, cylinder number 1 is typically located at the top or the front, depending on the orientation. Following the firing order, number 2 is next, followed by number 3, and then number 4. However, it's always recommended to verify with a service manual or diagram specific to the engine type.
The Chevy Blazer with a 4.3l engine has a firing order of 1-6-5-4-3-2. The number one cylinder is on the driver side closest to the front of the Blazer.
It's different with every car, some are marked, but the best way to find out would be to find a firing order diagram.
Standing in front with the hood open, looking at the distributor, number one would be at the 5:30 position on the cap, from there clockwise it goes 1, 6, 5, 4, 3, 2. I am assuming this is a 4.3L engine.

You really should get a repair manual for your car. The firing order for 1988 and later 4.3 liter V6 engines is 1-6-5-4-3-2, number one is driver's side front on the distributor and rotation is clockwise. Number one cylinder on the engine is driver's side front, number two is passenger side front and the rest follow the same pattern.
To find the number one firing position on a 454 distributor, first ensure the engine is at top dead center (TDC) on the compression stroke for the number one cylinder. You can do this by removing the spark plug for the number one cylinder and rotating the engine until you feel air pressure or see the piston reach its highest point. Once at TDC, the rotor of the distributor should be pointing directly at the terminal for the number one cylinder on the distributor cap. This indicates the position for firing.
take number 1 spark plug out and bring that piston to top dead center. Then take distributor cap off. Locate which tower the rotor is pointing to on the cap. That will be the number 1 plug wire. Then just follow the firing order. The rotor should turn clockwise.
