The 3.8 Liter V6 firing order is 1-6-5-4-3-2 not to get to technicial but it is actually a 3800 engine, there is slight difference in the 3.8 engine ( the type 1 or type 2), however Clay still har the correct firing order 1-6-5-4-3-2
do you still need the firing order? if so this is it: 1-4-2-5-3-6
the firing order is 12784563 you can also check valve cover still maybe on there or go to 401 nailhead-v8buick.com
Yes, you still need to make sure that the plugs are firing when it's their turn.
they still use the older sequence 18436572
the firing order is "18436572 as any othe v8 of gm during those years. It is still locked in my brain.lol
most cars have a diagram under the hood or in the owners manual if you still have one 1-4-3-2 firing order.
I think it is 1-6-5-4-3-2. If the factory intake is still on the engine look on it the firing order is usually on it.
I believe the 1993 firing order is still ( 1-5-4-2-6-3-7-8 ) distributor rotor turns COUNTER CLOCKWISE on the 5.0 L
The order is 1243 I beg to differ:- I own a 1969 Cortina Gt 1600 engine - 2737E 6015B, fitted with Original 32DFM Weber.( and it still runs LEADED Fuel) Firing order is 1,4,3,2.
The firing order on the Ford 302 has not changed and is still 1-5-4-2-6-3-7-8. The firing order on the Ford 302 HO however has been changed to 1-3-7-2-6-5-4-8 which is the same as the 351.
Trying to get my car to start as it over heated the other day so I changed the Harmonic sensor and the cam angle sensor. And still not starting but it has spark. Anything you can suggest
