code problems

[Kyle Means]

Had multiple codes when it stalked and wouldn't start. Addressed all issues pertaining to codes still wouldn't stay running. Codes are no activity in o2 sensor 1on both banks ignition primary and secondary circuit and random misfire. I've replaced fuel system minus injections, complete ignition system, cool, cap, rotor, plugs , wires, ignition module,PCM, ignition key and switched. Gone through all the relearn procedures, finally running now but has random misfire, no activity at o2 sensors 1 at bank 1+2  and ignition coi primary/secondary circuit codes. What's next?

With that many issues, sounds like a wiring/ground problem.
