With over 15 years of experience working on diesel engines, In this article, I will explain the firing order of the 6.0 Powerstroke engine used in Ford trucks from 2003-2007. Let’s get into it!
6.0 Powerstroke Firing Order
The firing order of the 6.0 Powerstroke is 1-2-7-3-4-5-6-8. which simply means the first cylinder to fire is 1 then followed by cylinder 2 then 7, and so on, until the last cylinder to fire, which is 8.

6.0 Powerstroke Firing Order Diagram
With this knowledge, you’re now well-prepared to address engine issues related to cylinder firing in the 6.0 Powerstroke. This information is critical for troubleshooting injector problems and ensuring precise timing for optimal engine operation.
Cylinder Numbering and Position in the Ford 6.0 Powerstroke Engine
On the Ford 6.0 Powerstroke engine, cylinder number one is located at the front of the passenger side of the engine.
This positioning is typical for V8 engines in American vehicles, where the numbering usually starts at the front of the engine on the passenger side.
This is followed by the cylinder directly opposite on the driver’s side, which is cylinder number two. The sequence alternates in this manner across the engine (refer to the Diagram below)
Importance of Firing Order on a 6.0 Powerstroke Engine
Now, let’s look at why the correct firing order is crucial to the operation of your 6.0 Powerstroke engine. Here are some of the reasons why:
1. Affects the Engine Performance
The firing order plays a vital role in the engine’s performance. When the cylinders fire in the correct sequence the engine runs smoothly and efficiently.
However, if the firing order is incorrect, it can lead to engine misfires, the car running rough, and a lack of power.
Additionally, the correct firing order ensures that the engine’s power is distributed evenly among all the cylinders.
If the firing order is incorrect, some cylinders may receive more power than others, leading to an imbalance in the engine’s performance.
2. Affects Fuel Efficiency
Another main reason why the correct firing order is important on a 6.0 Powerstroke is that it affects fuel efficiency.
When the cylinders fire in the right order, it allows the engine to burn fuel efficiently, resulting in better fuel economy.
whereas, an incorrect firing order can cause the engine to burn more fuel than necessary, leading to reduced fuel efficiency and increased emissions.
Therefore, the correct firing order is essential to ensure optimal engine performance and fuel efficiency.
My Tip as a Mechanic: Always remember If you are working on a 6.0 Powerstroke engine, it is important to follow the correct firing order and cylinder numbers to ensure optimal performance.
