How do I rewire spark plugs from coil pack on 2003 Windstar that was taken off

You will need to consider whether it is the primary or secondary side of that coil that fails if possible. A primary side failure could be a failing engine control module causing excessive current to the coil causing it to burn out or internally short. If it is a secondary side failure, the issue is still high current, because the spark voltage is not delivered straight to the plug caused by leakage of the spark in the plug wire to ground, or plug gaps that are too close. Some coils are wired to fire two plugs simultaneous, one upon compression and one (probably) during exhaust in a series circuit, so check both gaps on that coil. And the other possibility is caused by not using resistance plug wires in favor of solid copper and non-resistive plugs as well, causing the secondary current to be very high.

I can't reason why any sensor would cause the coil failure. The basics for coil operation is a quick pulse of voltage to the primary causes a induction of voltage in the secondary when the voltage is removed from the primary. Usually the current in the primary is quite high to create the magnetic field for the secondary. It was the same for old point & condenser distributors as it is now for solid state controls. The problem now is that the solid state MOSFET's used in place of points can develop internal leakage or short altogether. This takes out the coil pack because of the ECM failure.

You are using Autolite plugs right? I find OEM plugs work best rather than trying things like Iridium or other performance options.

I forget which pack went out on my Freestar, but it was OEM coil pack, OEM plug sires & OEM plugs all the way!

Coil packs was the problem in the first place. When a spark plug misfires, the high voltage goes no where and the coil starts to deteriorate. After prolonged misfire the coil will not make the hi voltage necessary to fire the plug. Replace the coil packs.

why did you only replace the plug.you don`t say.it could be a fuel problem,some of these had problems with the coil packs and or the wiring to the coil packs not working as intended.check these out.

the pick-up coil been checked

follow your spark plug wires from the spark plug to where they plug into. That will be your coil pack. It's not like the old days where your plug wires plugged into a distributer cap. Your coil pack is your distributer cap. I hope this helpes and wish I had a picture for you but if you follow those wires it should be no problem. Good luck.

The ignition coil (coil pack) is what generates the spark to the spark plugs. They're square black box with terminals that the spark plug wires run from to the spark plugs.

Has only one ignition coil pack, it control's all six spark plug's, all six spark plug cable hook up to the coil pack, hope this was very helpful.
