Need the firing order for 1999 Chevy S-10 4 Cyl 2.2L

I think on the 1999 V6 the firing order is 1-6-5-4-3-2. Stand with the engine pulleys and belts nearest to you. The cylinders are number as Odd and Even. The LEFT side is the EVEN numbers, (2-4-6). Number Two is nearest to you and Number 6 is furthest away from you. The RIGHT side is the ODD numbers, (1-3-5). Number One is nearest to you and number Five is furthest away from you.

hope this is a help

1-8-4-3-6-5-7-2 Distributor rotates clockwise vehicle , #1 cyl is on left side of engine

The firing order on Chevy s-10 2.5L 4 cyl is 1-3-4-2. And it goes in clockwise order. Looking from the "front" of the engine (where the water pump/fan is) No 1 on the distributor is upper right (2 o'clock). --------- Thanks.Helpmech.

Here you go.

need to know what engine there are two 4 cyl's and one 6 cyl

I apologize for the late response...Due to the bad economic situation this site has had a substantial (+50%) increase in the number of questions being asked in the last four months.
I assume you have a 4.3L and not the 2.2L?

For the 4.3L:
Firing Order:
1-6-5-4-3-2

Cylinders:
6-----------5
4-----------3
2-----------1
(front of vehicle)

Distributor:
coil wire-->
-----6------->............<--------5-------
-----4------->............<--------1-------
-----2------->............<--------3-------
............(front of vehicle)
