91 Explorer,EDIS, 4.0 distributerless. Was running fine then it dropped the center 2 cyliders at the coil pack, no spark at the coil for those 2 cylinders.Replaced the spark plugs and wires, it ran exactly the same on 4 cylinders. Replaced the coil 3 times no spark on any cylinders after coil replacement. There is 12 volts power to the coil pack. Replaced the module no change. No trouble codes in the computer. This has happened on both my explorer and my turbo charged Thunderbird, same problem. Problem started in both cars after being driven in heavy rain.
 
Have you midified anything under the hood, or are they both bone stock?
