Why doesnt my 1993 ford t-bird v8 5.0 not spark?

I have a 1993 ThunderBird LX V8 5.0 and the car wont start, its not getting a spark. The engine turns over and cranks. I replaced the ignition coil, replaced all spark plugs and wires properly.The alternator is fine , the battery connection is fine, the starter is fine, i added extra ground wires, the distributor cap and rotor is new, all the fuses are good, all other cables and wires are clipped in all the way, i have a very detailed repair manual, and i still hav'nt found the problem yet. I have done everythign i can think of except swap out the computer. 3 days ago the problems started, I was having a hard time getting the car started. Once it did start it would start right back up every time i turned the car off. Each day after sitting overnight it was hard to start in the morning. Today it would not start at all and now there is no spark. I have an older brother who is a mechanic that looked at it and still we cant figure out what is wrong. Please Help SinsOfUs@hotmail.com

Replace the Thick Film Ignition (TFI) module that Ford recalled on many of it's cars and trucks.

sounds like the computer
Bad distributor.
I am not sure of the recall but I do know that that if the car is distributor-less then there are 2 sensors that need to be check as well .

1: Is called a crank sensor the other is called a cam sensor .Those 2 work together with the ECM in witch the control and distribute Ignition fire order as well timing.
