86 5.0 No start, (NO SPARK) H-E-L-P-!

Well, I just installed a new thermostat and now the car wont start. In the process of removing the bottom bolt on the water neck, I loosened the distributor to swing it out of the way. After getting it all back together and it not starting, I checked the coil and I had no spark. I bought a new one and still no spark. Is there anything near the distributor (that I may have pulled loose or something) that would cause the coil not to give spark? I have power to the red wires at the coil connector.
What is the wiring diagram of the coil connector?
Thanks,
Jeff.

The timing should be. It did run fine, and I only had the dist. loose. (Not out). I have tried to move it, but I would thing that I still would have spark from the coil?
I read in the service manual (of course this was after the fact) That when rotating the dist. not to grab/move it by the wiring connector. That is what I did! I says that doing this would separate the connector inside causing a no start, or intermediate stall condition? It said that you could tell if this happened by a visual inspection, but I couldnt tell?

So how ya gonna check the timing with NO spark??????????

Likely you killed the TFI module on the dist... Pull the plug then reinsert it, MAYBE it will work again. If not repl the module

I think that the TFI may be my problem. I looked on autozones web site and couldnt find one. Is this just a dealer item?

Actually the part number is F121, costs about 30 to 40 bucks.  its an ignition module to them, not a TFI.
