Sparkplug firing order for a 1988 s10 pickup - 1988 Chevrolet S-10

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.

What engine? If it's a 4.3, the order is 1-6-5-4-3-2

if its a 2.8L then 123456, can't remember the 4.3L. just type the question in your address bar,include engine size for more accuracy.

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)

sounds like ignition module inside of distributor cap under distributor rotor button.these do go bad and can easily be replaced.strong suspicion from your details that this is the culprit.
