I think you need more definitively hard-data testing. You got a new coil(s), different PCM, wires maybe/probably good, so you need to either measure signal waveforms with the o-scope or assume they're good for now.
Focus on the injectors. Get the noid light or use o-scope. Yank em out clean em and check resistance. O-scope them too.
Pull plugs and let's see em.
Codes?

To not leave everyone hanging in suspense and in case this helps anyone in the future, I got it repaired. I doubted it was the PCM. So, decided it had to be in the wiring between the PCM and injector rail. I decided to try the plug first. Bought a new one with 6” of wire. Then cut off the existing plug and about 2” of wire. Spliced the new in. Cleared codes and fired it up.
