I wanted to know the firing order for a 1993 Chevy s10 4.3 litre. And where no. 1 cylendar is located?

As far as I know, all chevy 350s are the same.

For the 1996 Mazda 626 2.0L DOHC In-Line 4-Cylinder:

Firing Order:
1 - 3 - 4 - 2

Cylinders:
.........(back).........
|..1....2....3....4...|
........(front)

Distributor:

/////////////////| <---2

//////////////////////////| <------1

Let me know if this helped and thanks for using Fixya!

To answer that question you need to follow the plug wire from the # 1 cylinder to the cap. #1 cylinder is the first cylinder located at the far from of the drivers side portion of the engine. (left side) The cylinders are numbered even and odd, so 1,3,5 left and 2,4,6 right. The firing order is also located on the intake manifold directly in front of the distributor.

For the 1993 Chevrolet S10 Blazer 4.3 V6, Both: 2WD AND 4WD:
