Would anyone be able to help me make sense of this? DTC codes P0325 and P0330 are on, which means both knock sensors (bank 1 & 2) are on. What could cause this issue?

I also have another issue where it takes longer than it should start. Could this be caused by these bad knock sensors? I think if they are malfunctioning it could alter the timing a bit, maybe that's the cause of the hard start? Are there any other known problems for these gen 3's that could cause a hard start or a longer crank time before it starts?

Has this truck had any minor or major repairs recently? Have you looked to see if both knock sensors are properly connected? Are they mounted correctly and the fasteners tight? Is there oil all over the wiring harness behind the oil filter?

Knock sensor issues can make the engine hard to start because if the sensors are sending an incorrect signal to the PCM the PCM can retard the timing so much that it may not start at all. If you could get a scan tool connected to this truck and look at the PCM data you could see what the knock sensor voltage is at. You could also see if the cam/crank correlation is correct and see what the fuel control looks like.
