1993 Explorer Crank no start (1997 PCM)

Hello, I wanted to ask why my explorer is not starting. It is a 1993 Ford Explorer eddie bauer 4.3 OHV. I have a 4.0L supercharger with 5.0 injectors and its bored out to 4.3L with a stroker cam kit. I bought it used and the owner doesnt know what happened to it. It had apparently been running until he left it under a cover and after about a year he decided to sell it.

It cranks but does not start. I have confirmed fuel pump performance (after replacing it) with good pressure to the fuel regulator (60psi) and to the fuel rail. It has a completely custom aeromotive fuel system. Pump all the way to the regulator is made by aeromotive with redhorse performance hoses and A/N fittings. I have also confirmed spark. It still does not start. I have tried starter fluid and that was when it bucked a little bit, started and was extremely rough. It "ran" on its own, like ****, for maybe 10 seconds and shut off. I do not know what to do.

For more details, it has a 1997 PCM because the original owner wanted to swap to OBD2 I am assuming so he could more easily have it tuned to run to spec. I have tried a scanner to no avail. I confirmed that the port is receiving power and has solid ground by testing pin 4,5 and 16.
