The very fact that you mention specifically cylinders 2, 3, 5 & 8 being dead in your post is what lead me to advising you check that middle connector on the FICM because that is the very connector that services those four cylinders. My next step would've been to run an injector buzz self-test paying particular attention to the four cylinders in question. If no mechanical clicking noise was heard from those very four injectors, I would then have plugged in my home-made "noid light" into the injector connectors one by one, to compare the brightness which I assume would've lead to those four cylinders not lighting up at which point would lead to a problem with the circuit(s) or the FICM (not as likely, but still a possibility).
To verify the FICM is functioning, you simply need to access the three FICM voltage PIDs (FICM_L, FICM_M and FICM_V). FICM_L and FICM_V should be reading at or around battery voltage (approximately 12 to 14 volts). FICM_M is the most important of the three. If it decreases to any less than 45 volts it will set a P0611 FICM performance DTC, at which point it needs to be replaced. Optimum FICM_M voltage readings are between 47.5 to 49 volts.
