What is the firing order for a 1973 Pontiac Bonneville?

The firing order for a 1973 Pontiac Bonneville depends on the engine it has. Bonnevilles of that year came with several different V8 engine options. You'll need to know the engine's displacement (e.g., 400 cubic inches, 455 cubic inches) to determine the correct firing order.

Without knowing the engine size, I can't give you the precise firing order. You can usually find this information:

* On a sticker under the hood: Many cars had a sticker with engine specifications, including firing order.

* In the owner's manual: If you have the original owner's manual, it will list the firing order for your specific engine.

* Online: Search for "[Your Bonneville's Engine Size] Pontiac firing order" (e.g., "400 Pontiac firing order"). Many automotive websites and forums have this information.

Provide the engine size, and I can try to help you find the firing order.
