Firing OrderIt is 1-5-3-6-2-4.

( also , the distributor rotor turns CLOCKWISE , the distributor cap is installed with the marked # 1 position facing AWAY from the engine , and the engine cylinders / spark plugs are numbered 1 through 6 , from front to rear )

See this page,http://autorepair.about.com/library/firing_orders/bl-fo-8571.htm

I set my 1992 EFI 4.l just like this and it runs like a top. Note my engine code in the VIN is a 'Y'.

To avoid confusion, replace spark plug wires one at a time.

Ford Engines;

144,170,200,240,300 (6-Cylinder) Inline

Firing Orders: 1-5-3-6-2-4

Distributor Rotation: Clockwise

The above is correct. I have been doing mechanical work, and my own tinkering for 50 yrs, and have never seen an inline 6 that did not fire 153624.
