The 1993 Ford Ranger 4.0L engine uses a distributor,
not individual coil packs. Therefore, there's no "coil pack firing order" in the same way a multi-coil setup would have. The firing order is determined by the distributor's rotor position and cap wiring.
The firing order for the 1993 Ford Ranger 4.0L is 1-3-4-2.
