What is the firing order diagram for 5.4l ford?

The firing order for a 5.4L Ford engine depends on the specific model and year. However, there are two common firing orders for these engines:

For most 5.4L Ford V8 engines:

* 1-5-4-2-6-3-7-8

For some older models (pre-2003):

* 1-3-7-2-6-5-4-8

How to determine the correct firing order for your specific engine:

1. Locate the engine block number: This is usually stamped on the engine block near the front.

2. Use the engine block number to look up the correct firing order: You can find this information in a repair manual, online, or by contacting a Ford dealership.

Example: A 2004 Ford F-150 with a 5.4L engine would likely use the firing order 1-5-4-2-6-3-7-8.

Note: It's always best to confirm the firing order for your specific engine model to avoid any issues.
