Thats because usually when they go out you need a new engine. Last thing on their mind is the oil pump. A buddy of mine's 00 spun a rod bearing when his oil pressure dropped to 0 and he never seen it.. Never figured out if the oil pump was actually bad, but we did find some of the orifices the oil goes through to lube the bottom end were clogged up with some junk. You're lucky you caught it in time.
