What we have done: We started with an 88 5.0 and swapped it into a 90 mustang and fried the cpu on the 90, then we tried the cpu from the 88 and fried that, next we tried rewiring the entire engine with painless, but we now have problems with the car not turning over, we figured out the starter was not grounded properly, but now it seems as if we're not getting any kind of spark in the combustion chamber. We tested the fuel harness, but everything checked out. It has a new cap, rotor, plugs, and wires. At wits end, please let me know any suggestions. Thanks

Did you check the TFI sensor?
