What is the Firing order on a 93 Lumina Z34 with 3.4 DOHC. Some one tryed to change the own wires and now it doesnt run. Cant find this engine in the shop manual. I think some one must have moved coils around on the module because all numbers match.

I'm pretty sure that the firing order is 1-2-3-4-5-6.

I gues since this is distributerless I need coil wire placement. Is it the same as a 3.1?

Coil order should be, left to right, 1-4 6-3 2-5
Firing order is 123456 as fopu said
Cylinder location is
1-3-5
2-4-6
