F250 FIRING ORDER 6 CYLINDER 1... 5... 3...6 ...2 ...4.
Distributor rotates counterclockwise. Firing order: 1-5-4-2-6-3-7-8
1-3-7-2-6-5-4-8
Answer1,3,7,2,6,5,4,8 is the firing order. The cylinders are numbered 1-4 from front to rear on the passenger's side and 5-8 from front to rear on the driver's side. THIS IS WRONG. THE CORRECT ORDER IS 1,5,4,2,6,3,7,8, COUNTERCLOCKWISE ROTATION. FIRING ORDER IS ALSO LOCATED ON THE INTAKE MANIFOLD, AT LEAST IT IS ON MY 97 F250 HD 7.5, THE OIL COMPANIES JUST LOVE US.
That all depends on when it revs. It could be your cruise switch. If you have a manual transmission, don't use cruise until you're in high gear. If you resume and try to shift, the cruise will rev the engine even when you clutch.

1 - 5 - 3 - 6 - 2 - 4 The distributor rotor turns CLOCKWISE
On the front part
The Ford 4.9 L straight six engine spark plug firing order is ( 1 - 5 - 3 - 6 - 2 - 4 ) The distributor rotor turns CLOCKWISE
I'm not sure what it would be if it is a gas engine, but if its a diesel, its probably 1-5-3-6-2-4
