Firing order is 1, 5, 3, 6, 2, 4. Number 1 cylinder is up front. Why would you need the firing order, this engine does not have plug wires, each plug has its own coil pack, each coil pack is controlled by the computer.

Firing order 1.2.3.4.5.6
Looking at engine , number 1 cyl left front,number 2 left middle,3 left back
Number 4 right front,5 middle right ,6 back right
Fault codes indicate missfire cylinder 2 and 6
