Ford 6.0 Powerstroke cylinder numbering and firing order
Where cylinder 1 lives, how the other seven are numbered, and the firing order on Ford's 6.0L Powerstroke V8. Diagram-friendly reference.
On a Ford 6.0L Powerstroke V8, cylinder 1 is the front-most cylinder on the passenger side. Odd cylinders (1, 3, 5, 7) run down the passenger bank, even cylinders (2, 4, 6, 8) run down the driver bank. Firing order is 1-2-7-3-4-5-6-8.
If you’re chasing a misfire code, that’s the layout you need. The rest of this is the why.
Quick reference
| Cylinder | Side of engine (facing forward, hood up) | Position |
|---|---|---|
| 1 | Passenger (right) bank | Front-most, slightly forward of #2 |
| 2 | Driver (left) bank | Front-most |
| 3 | Passenger (right) bank | Second from front |
| 4 | Driver (left) bank | Second from front |
| 5 | Passenger (right) bank | Third from front |
| 6 | Driver (left) bank | Third from front |
| 7 | Passenger (right) bank | Rear-most |
| 8 | Driver (left) bank | Rear-most |
Firing order: 1-2-7-3-4-5-6-8
Ford rotates the crank in this sequence so two adjacent cylinders on the same bank rarely fire back-to-back, which smooths torque delivery and reduces vibration.
Why cylinder 1 is on the passenger side
Ford convention. On most Ford V8s including the 6.0L and the older 7.3L Powerstroke, cylinder 1 is the front passenger-side cylinder. (For comparison: GM small-block V8s number cylinder 1 on the driver side. So if you cross brands, double-check the manual.)
The two banks aren’t perfectly mirrored. The passenger bank sits a hair forward of the driver bank because the connecting rods share crank pins, which forces a small offset. That offset is the easiest way to tell which side is which at a glance: the one set forward is the passenger bank, holding the odd numbers.
Where the engine actually lives
The 6.0L Powerstroke is a 32-valve OHV diesel V8 built by Navistar (then International) for Ford, fitted to:
- 2003 to 2007 F-250, F-350, F-450, F-550 Super Duty
- 2004 to 2010 Ford Econoline E-Series vans
- 2003 to 2009 Excursion (early model years only for some)
It replaced the 7.3L Powerstroke in mid-2003 and was itself replaced by the 6.4L Powerstroke for 2008 Super Duty trucks. The 6.0L has a working reputation that’s, let’s say, polarizing, and that’s part of why these diagnostic questions come up often.
How to use the firing order for a misfire
If a scan tool throws P0301 (cylinder 1 misfire), you don’t have to guess which injector or glow plug to pull. Cylinder 1 is the front-right one. Same logic for the other codes:
- P0301 → cylinder 1 → front passenger
- P0302 → cylinder 2 → front driver
- P0303 → cylinder 3 → second-from-front passenger
- P0304 → cylinder 4 → second-from-front driver
- P0305 → cylinder 5 → third-from-front passenger
- P0306 → cylinder 6 → third-from-front driver
- P0307 → cylinder 7 → rear passenger
- P0308 → cylinder 8 → rear driver
Common 6.0L misfire causes worth checking before the injector itself: stiction in the injector spool valve (sticky cold starts), failed glow plug or harness, FICM low voltage (target is 48 volts, anything below 45 means a tired FICM), and high-pressure oil leaks at standpipes or dummy plugs.
A note on the firing order
Different sources occasionally list the 6.0L firing order as 1-3-7-2-6-5-4-8 (the 7.3L Powerstroke order). The factory service manual and the FICM programming for the 6.0L specifically use 1-2-7-3-4-5-6-8. If you’re cross-referencing online forums, watch for posts mixing the two engines.
Always confirm against the owner’s manual or the factory workshop manual for your exact model year before doing anything that depends on it.
