A bad O2 won't cause knock,but a bad fuel pump will. What is your fuel pressure at 22 lbs of boost?I finally found the problem for the knock. It was the o2 sensor. Put a new on on and 22 lbs of boost and 0 knock. I'm still not sure why my fuel pressure is dropping though.

It needs to be65. Do you have a new AC Delco fuel filter? What octane?The only other thing I did was take the torque strap off. Fuel pressure is at 60 psi when boost is at 22

fuel pressure seems to be raising 1 to 1. but it starts knocking at half throttle. I do have a hotwire kit. Key on getting 11.6 volts to the pump. i did notice when i turn key on i hear the pump run then stop but fp gauge is still at 0 psi until i start it. bl at cruise is 122
You'll want to check voltage with engine running.11.6 volts is with key on engine off. All the grounds are good. Ill have to check the rest later bc now I'm having transmission problems so I'm getting ready to tackle that.
