Hi,
You should check the trigger voltage at the coil, this comes directly from the engine ecu, the ecu output transistors have a tendency to fail usually due to low resistance in the ignition coil, unfortunately you will probably have to replace both or send the ecu off for repair and fit a genuine ford coil, good luck.
