Not much effort on your first post. Does your Internet service charge by the word?
What model year Mustang are we talking about?
Start by checking the electrical connector to the Coil pack. Look for bent/pushed pins. Especially the T/O wire.
Use a "noid" style test light to confirm a firing pulse from the PCM. If no pulse, bad PCM or wiring.
If firing pulse, likely a bad coil pack.
