Exclamation 1993 Mustang 5.0 crank but no start

cars been running a little rough at idle so i saw my plug wires melted from my headers, i changed them and protected them this time i started it up and it was running the same way a little rough so i messed with the timing and it kept backfiring, and all the sudden got a real rough idle (sounded like it had a big cam) i shut it off rechecked everything and my 4 and 8 plugs were wrong i switch them and tried starting her now she cranks but no start i changed the ign. module i have spark and fuel, cant figure it out

How in the world did you jack up so many plug wires? ONE AT A TIME SIR! Now I would assume that it won't start because you still have them wrong. Find the correct firing order which I can't remember and check that.

Woohoo! Try cleaning the MAF and when you replaced plug wires did you do the whole shebang (plugs, cap and button)?
