Fuse 4 has good voltage out of the left socket, continuity is good through the fuse.
Fuse 37 has voltage of 12.5 with Ignition OFF, and 11.9 with Ignition ON. What im assuming this means is theres a grounding issue thats telling K6300 to always be on? This could also help explain why the fuel pump is priming with ignition on without stopping at any point. But, this shouldn't stop the communication since its stuck in ON, correct?
Attaching Fault codes as imagines inline.
Side note, the o2 sensors were disconnected at the connector near the fuel rail, but not my main concern at the moment. From what I have read, Fuse38 also controls the ECM, so as a part of my early troubleshooting, I tried to keep it from shorting out.
