The firing order for a 1992 4-cylinder Ford Ranger is typically 1-3-4-2.
This means the spark plug in cylinder 1 fires first, followed by cylinder 3, then cylinder 4, and finally cylinder 2. This sequence is determined by the rotor position inside the distributor cap. You should double-check your engine's specific information on the valve cover or in a repair manual as there's a small chance of variation depending on the exact engine code.
