Default Spark plug Problem

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.
