What is the firing order of a 1995 Chevy Cheyenne pickup V8?

The 1995 Chevy Cheyenne pickup likely used either a small-block (SBC) or a big-block (BBC) V8 engine, and the firing order differs between them. There's no way to definitively know without knowing the specific engine displacement (e.g., 5.7L, 7.4L).

* Most likely (Small Block): If it's a common small-block V8 (like a 5.7L), the firing order is almost certainly 1-8-4-3-6-5-7-2.

* Big Block (Less Likely): If it's a big-block V8, the firing order would depend on the specific engine. You'd need to consult a shop manual or the engine casting number to determine the correct firing order.

To find out for certain, you need to:

1. Check the engine's displacement: Look for a sticker or casting on the engine block.

2. Consult a repair manual: A Haynes or Chilton manual for your specific year and model Cheyenne will have the exact firing order.

3. Check online resources: Websites like GM-Trucks.com or other Chevy enthusiast forums might have the information based on engine specifics.

Without knowing the engine size, the small-block firing order (1-8-4-3-6-5-7-2) is the *most probable* answer, but not guaranteed.
