1999 ford 4.0 firing order distributor?
The firing order for a 1999 Ford 4.0L SOHC V6 engine is 1-5-3-6-2-4. This applies whether it has a distributor or not. While some 4.0L engines used a distributor, many (especially later in the 1999 model year) switched to coil-on-plug ignition systems without a distributor. If your engine *does* have a distributor, the firing order is still the same, and the distributor cap's terminals will be numbered to match.
