SOURCE: Firing Order diagram for 2006 Ford Explorer

Hope this helps. The ignition coil:

  • changes low-voltage pulses from the PCM to high-voltage pulses.
  • fires 2 spark plugs simultaneously.
  • has 3 transformers.
    • One transformer fires the spark plugs for cylinders 1 and 5
    • One transformer fires the spark plugs for cylinders 2 and 6
    • One transformer fires the spark plugs for cylinders 3 and 4
Spark plug wires:
  • carry high-voltage pulses from the ignition coil to the spark plugs.
The spark plugs:
  • change high-voltage pulses to spark at the gap, which ignites the fuel and air mixture.
The firing order is 1-4-2-5-3-6.

I need the correct firing order diagram for a 1982 ford f150 351 windsor please help at least a link to a site


The firing order is ( 1 - 3 - 7 - 2 - 6 - 5 - 4 - 8 )

The distributor rotor turns COUNTERCLOCKWISE

The marked # 1 position on the distrubutor cap faces to the REAR and slightly towards the drivers side

The engine cylinders / spark plug locations are numbered :


firewall

4 - 8

3 - 7

2 - 6

1 - 5

front

If someone has altered the disstributer, pull #1 plug, put finger over hole, turn engine over until compression on that cyl, line up timing marks (ball park only) and rotor will be pointing at the correct terminal for #1 cylinder plug wire connection, in the cap.

Changed plugs and wires on a 94 ford explorer and now it 's not tunning right. need a diagram. please.

FIRING ORDERS NOTE: To avoid confusion, remove and tag the spark plug wires one at a time, for replacement. If a distributor is not keyed for installation with only one orientation, it could have been removed previously and rewired. The resultant wiring would hold the correct firing order, but could change the relative placement of the plug towers in relation to the engine. For this reason it is imperative that you label all wires before disconnecting any of them. Also, before removal, compare the current wiring with the accompanying illustrations. If the current wiring does not match, make notes in your book to reflect how your engine is wired. Fig. 1: 1991-94 2.9L and 3.0L Engines Firing order: 1-4-2-5-3-6 Distributor rotation: Clockwise 85552008.gif
