The firing order on a 2000 Chevy S-10 depends on the installed engine. The truck could come with either a 2.2-liter inline-four or a 4.3-liter V6. The two common firing orders are: 2.2L I4 = 1-3-4-2; 4.3L V6 = 1-6-5-4-3-2. This article covers both possibilities and how to verify the correct sequence for your specific vehicle.
Engine options in the 2000 S-10
In 2000, the S-10 offered two main engine options. The firing order you use depends on which of these engines is installed in your pickup. Use the manual or engine stamping to confirm the exact order for your individual truck.
2.2L inline-4 (2.2L I4)
The 2.2L inline-four uses a four-stroke ignition sequence. Its firing order is 1-3-4-2.
Firing order for the 2.2L inline-four:
- 1
- 3
- 4
- 2
Always verify with the service manual or a sticker on the engine block/valve cover to ensure correct wiring, as ignition configurations can vary by year or market. If your setup uses a distributorless ignition with coil packs, the same sequence applies, though the physical wiring path may differ.
4.3L V6 (4.3L V6)
The 4.3L V6 is a 90-degree V6 with six cylinders. Its typical firing order is 1-6-5-4-3-2.
Firing order for the 4.3L V6:
- 1
- 6
- 5
- 4
- 3
- 2
As with any ignition system, be sure to confirm the exact sequence for your specific vehicle using the owner’s manual, a service manual, or a decal on the engine bay, since variations can exist between model years or ignition configurations (DIS vs. distributor-based systems).
Summary
For a 2000 Chevy S-10, the firing order depends on the engine installed. The 2.2L inline-four uses 1-3-4-2, while the 4.3L V6 uses 1-6-5-4-3-2. Always verify the exact sequence on your engine via the service manual or factory labels to ensure correct spark plug wiring and optimal engine performance.
What year is S10 to stay away from?
There isn't a year of an S10 or generation that you should avoid. They're a reliable compact truck. As someone with a fairly high optioned 99 s10, this is accurate. There's so much oddball crap on that truck it's a little aggravating.
