Ford 4.6 and 5.4 Triton firing order and cylinder numbers

The Ford 4.6 and 5.4 modular V8 (Triton) fires 1-3-7-2-6-5-4-8. Cylinder 1 is the front cylinder on the passenger side (bank 1, RH bank).

Drag to turn the engine, scroll or pinch to zoom. Orange = the cylinder firing now; the numbers on the coils are cylinder numbers. Driver and passenger sides are for left-hand-drive vehicles.

Top view, front of vehicle at the top. Engine runs front to back. Firing order 1-3-7-2-6-5-4-8. Large numbers are cylinder numbers; the small orange numbers give each cylinder's place in the firing order. Cylinder 1 is filled.

Where each cylinder is

CylinderMisfire codeLocationPlace in firing order

Bank 1 is always the bank that contains cylinder 1, so for this engine bank 1 is the RH bank with cylinders 1-2-3-4; bank 2 is the LH bank with cylinders 5-6-7-8. Oxygen-sensor, camshaft and catalyst codes that name bank 1 or bank 2 use the same split.

How to find a cylinder on this engine

  1. Find the front of the engine: the end with the drive belt and pulleys.
  2. Find bank 1, the RH bank that holds cylinder 1. On this engine it is the passenger side.
  3. Count from the belt end. Cylinders 1-2-3-4 run along bank 1 and 5-6-7-8 along bank 2, each starting at the belt end.
  4. Match the code: P0301 is cylinder 1, P0302 cylinder 2, and so on. P0300 means a random or multiple misfire and does not name a cylinder.

Questions

What is the Ford 4.6 / 5.4 modular V8 firing order?

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

Which side is cylinder 1 on?

Cylinder 1 is the front cylinder on the passenger side (bank 1, RH bank).

Where is cylinder 4 (code P0304)?

Cylinder 4 is the rear cylinder on the passenger side (bank 1, RH bank).

Which bank is bank 1?

The bank with cylinder 1: the RH bank, cylinders 1-2-3-4.

Is the 5.4 firing order the same as the 4.6?

Yes. Ford's 2004 workshop manuals give 1-3-7-2-6-5-4-8 for both the 5.4 F-150 and the 4.6 Crown Victoria, with cylinders 1-4 on the RH (passenger) bank.

Is it the same as the 5.0 HO?

The sequence 1-3-7-2-6-5-4-8 matches the 5.0 HO and 351 Windsor, and the numbering follows the same Ford pattern (1-4 on the passenger side). See the Ford 302 page.
