To determine the firing order, I need to know the engine size and type.
Here's why:
* Different engines have different firing orders. Toyota trucks from 1986 could have had a variety of engines, including 2.4L 22R, 3.0L 3RZ, and 4.0L 22RE.
* The firing order changes based on the number of cylinders.
To get the correct firing order, please tell me:
1. Engine size: (e.g., 2.4L, 3.0L, 4.0L)
2. Engine code: (e.g., 22R, 3RZ, 22RE)
Once you provide this information, I can give you the accurate firing order for your 1986 Toyota truck.
