The firing order for a 2003 Ford F-150 with the 4.6L V8 engine is 1-5-4-8-6-3-7-2.

Locating cylinder #1 requires a bit more description as it depends on your perspective. Looking at the engine from the front (the radiator side):

* #1 Cylinder is on the passenger side (right side), at the front. It's the furthest forward cylinder on that side.
