Yes there is, or at least their should be. I just got my Taurus so I don't know the tips and tricks and pitfalls of Ford cars, but this is how I'd test my ignition coil on both my 86 Fiero GT, 87 Fiero GT, 96 Saturn SC2, and my 93 Geo Storm.
When my previous cars wouldn't start, one thing I'd do was to pull the wire that comes from the DistCap (DC) to the IgnCoil (IC). You'll want to leave the the DC side of the wire plugged to the DC and the other end just needs to be temporarily out of your way.
Ok, in a perfect world, when you try starting the car the (now exposed) IC post should energize and send an electrical charge down the wire you just unhooked to the DC's center post which charges each individual plug in order. With the wire off of the IC, when the car is being cranked, your IC is good if you see the IC Post start sparking (kind of a tesla or plasma ball effect). In summary, if you see sparks, the Ignition coil is good. In the previous example, if the coil showed that it could get and send spark, the next culprit was usually the Ignition Control Module, but that might not apply to your case. I did have 2 plug wires backwards once and it stuttered really bad until I went back and double-checked the firing order diagram for the DistCap-->SparkPlugWires-->SparkPlugs.
Hope it helps.
I think Advanced or Autozone will test ignition coils and Ignition Control Modules for free ().
