Please provide me with the following:
* Engine code: You can usually find this on a sticker or tag on the engine block.
* Model: The specific model of your Nissan truck (e.g., D21, Datsun, Pathfinder).
* Engine size: This will help narrow down the possibilities (e.g., 3.3L, 4.5L).
Once I have this information, I can provide you with the correct firing order.
