Check the compression, there may be a valve timing issue. Also check the firing order.

Firing order has been checked and is correct. Compression is good.

“Compression is good” doesn’t mean anything. You have 6 cylinders. A proper check of compression gives you 6 numbers in psi. What are the numbers?
