The easiest way to test ignition coils on a 1992 Mustang 2.3 is to use an ohmmeter on the leads going into the coils.
If you don't have spark at the plugs, or at the distributor cap, the problem is probably a faulty ignition module. This is located under the distributor cap and ignition rotor. You need test equipment to check the coils, modules and pole pieces.

first check to see if your distributor is getting power to it and if it is check to see if the stator inside your distributor is sending a signal to the ignition module, just hook up a test light between the stator going to the ignition module to ground
to check the ignition coil on the B18 you need to go to the little black box (distrubitor) where your spark plug wires are located and unscrew the 3 screws you will see. well first you need to disconnect the battery. then take a test light and see if it has power, and if not you need a new one. and if you need a new distrubitor, i have one...email, basketballpjb@aol.com
let the engine running, lift off the ignition coil one by one after opening the screw...a tick sounds will be heard ... no tick sound and gasoline leak on the plug thread means the ignition coil is busted.
start the engine if it runs its good

Hello, Jamison here, You need to remove the coil that is not working, You can test it with an OHM meter, You will need to have an idea of where it should be first, If you can not find this information, You can remove all 3 coils and test all of them, if one is bad You will know by the difference in resistance, If it turns out that they are prety close, It could be the ignition module, This type of PCM setup is sort of like haveing 3 different ignition systems. Most parts stores can NOT test coils for you, but most of them CAN test the ignition module. Good luck, Jamison.
most times it is a bad coil pack there are three ignition coils mounted on top of the ignition module. one coil supplys 2 cylinders with spark. original coils have the cylinder number stamped on the coil so you know what coil feeds #y cylinder. 80 percent its a coil failure 20 percent the module fail and signal is interrupted to coil.if you don't want to just change coil.without proof,you can switc coil with another remember to mark the number of the cylinders on the ignition wires before you switch coils as the coils have a firing order that must be followed. when you switch coils and test drive check the coses for misfire again if the miss moves to a different cylinder number the coil is bad. if the number is still four with the coils switched,the ignition module if probably bad, these coils usually tes good when you ohm test them but these coils usually break down under engine load and heat,your coil can pass a ohm test but still be bad. there cheap enough just put new #4 coil in it. p.s you need a 5.5 millimeter socket to remove coils
The generic number given for wire resistance is 1000 ohms per foot
Does it turn over? Does it have fuel, spark, compression? Is ignition timing correct?
ignition module on what?

Many autopart stores have a machine to test it. The machines use a universal adapter to hook into the ignition control module. The ignition control module is in the distributor. If you mean the part that contains the ignition coil, when mine went bad I probed it with an ohmeter and then asked the parts store if I could test the resistances in a new coil before I bought it. Since the resistances of certain terminals weren't even close, I knew I had a bad coil.
First, see if the each coil is getting the required voltage from the ignition switch (probably 12V). If they are, you can check the resistance of the coil with a simple volt meter. Should read minimal resistance. If the meter reads OL then the coil windings are open (defective/bad).
