The firing order is 1-2-3-4-5-6
The cylinder #
From the firewall, passenger to dives side 1-3-5
From the radiator, passenger to drivers side 2-4-6
On the coil pack from passenger to drivers side
5-2-3-6-4-1
Good luck and keep me posted, be glad to answer any other questions you may have.
If it's distributorless (coil packs) 3.4L, here you go, but firing order is - 1-2-3-4-5-6. My info shows the firing order you have is for 3.8L. Hope this is it.
