To find the correct firing order for *your* specific Jaguar 4.0L V8 engine, you need to:
* Locate your engine's identification number: This is usually found on a plate attached to the engine block.
* Use that number to search online resources: Jaguar's own service manuals (often available online through subscription services or forums) or reputable automotive repair databases will contain the firing order specific to your engine's configuration.
Without knowing the specific year, model, and engine code, I cannot provide the correct firing order.
