See Diagrams Below for Distributor & Coil Pack Stule Ignition Systems on Ford 1.9L.

Please note that the OEM ignition coils on your vehicle are marked with the cylinder numbers. See diagram.

Check this diagram for 2003 Ford Expedition 4WD 5.4 liter SOHC V-8 VIN "L"...



Hope helps (remember rated this help).

The ignition coils are listed from 'A" to "L" (up to 12 cylinders) and they are in sequence according to the firing order. This diagram will help you out, and according to this diagram for your vehicle, "E" is the fifth letter so the fifth cylinder in the firing order is cylinder #6, and as you can see from the diagram that coil "E" or cylinder #6 is the second spark plug or cylinder from the front on the drivers side of the engine.

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.

For the 2.8L DOHC V-6:
Firing Order:
1-5-3-6-2-4
Cylinders:

Attach the spark plug wires in the firing order. The firing order should be in your owner's manual. It also might have a diagram next to your ignition coil pack. The ports on the coil pack are shown by the diagram.
