Code 30 with a slight knocking noise???

[sprtnwd4yamaha]

I am getting a slight knocking noise from my turbo boosted 07 apex motor (1500 miles) along with the code 30. I know that the code 30 is an oil pressure issue. is my oil pump out or is it something worse. When the knocking started i immediately shut it down and towed it out. what should i do next. New motor? or is it a quick fix?

thanks.

oil pump lost prime.. take it to someone that knows how to get it primed theres check ball in oil pump
and can be very tricky but if its knocking thats bad news may need bearings and a crank
