Welcome to FTE.
This puppy is OBD-1 diagnostics so its engine controller / computer can be scanned with or without a OBD-1 code reader or scan tool by following one of these test hook-ups to look for trouble code clues that can help focus a trouble shoot. Ford OBD/OBD2 Codes – TroubleCodes.net, scroll down to view various wiring options to have the Dash CEL blink the codes, or have a under-hood 12 volt test lamp, LED of choice blink them, or a analog multimeter wave, or 12 volt buzzer sound the codes
A code reader is easer & more accurate, so is a OBD-1 capable scan-tool like the Actron CP9145 & 9150 & other OBD-1 capable scan-tools that can hook up to our under hood OBD-1 DLC to query the engine controller, as it can also put up live PID data for viewing thats really useful in most engine trouble shooting.
So consider beginning with doing that & post up All code Numbers & the forum can likely advise the next best item to put on your suspect list. Some initial thoughts for consideration.
All that said, seeing as how you have voltage to the coil but no spark, the ICM = Ignition Control Module, that switches the coil primary voltage to make spark, that may be distributer or inner fender passenger side mounted, never liked all the under-hood heat, so is a good suspect. Ford finally moved my 94 Taurus 3.8L ICM out of the engine compartment up under the windshield passenger side leaf screen where its still happily having the coil make a good hot spark!!! lol
When checking for spark, its a good idea for us to use our inductive timing light on a spark plug wire or coil HV output lead, to safely for us & our ignition system components, check for spark.
Some beginning thoughts for consideration, let us know how it goes.
