Default Spark Plug Problems

I am hoping that someone can help me figure out what is wrong with my mustang. I bought it for $1000 dollars(bad fuel pump, wouldn't start,at least that's what the seller told me) Changed fuel pump=no start.Ended up changing:fuel pump,alternator, coil, wires, cap, rotor, distributor, ignition module, fuel pump relay, power relay, battery, starter, battery cables, ground cables, computer, ignition switch, new ignition module and if i could think of anything else, i would probably change it too. (got more money than good sense).Fuel pressure is 40#,tested injectors with noid light and they are working, pulled them all and had flow checked=all good. Still won't start. Pulled new spark plugs and they are all black looking(see attachment), can anybody help me? From now on when a deal sounds too good to be true i am going to start slapping myself until it don't sound good no more.

Where in TX are you located?? Sounds like it is something simple but I would have to see it in person. I noticed you haven't said anything about setting the timing again just to be sure its right. Get a pic of your engine bay up

if you have spark, fuel and air... did you check to make sure you are timed correctly, and that the car has the proper air metering instruments?

I'm in S.A. MAF is fine, Barometric pressure sensor is fine, IAC is working, no air or vacuum leaks. However I did pull a compression check yesterday and i've lost compression in all eight cylinders, highest reading was 50PSI. Looks like it is time for a teardown.
