wheres your oil pressure gauge sit? help

Mine sits much higher on the "NORMAL" than yours. I think it's around the "A".

I don't know how to verify whether or not you have enough pressure. Your gauge could be broken, of the oil pressure switch could be bad. Someone here will chime in.

If you decide to replace the oil pump, you need to remove the oil pan to replace the oil pump. But like said before, it isn't very difficult. You just need a new oil pan gasket.

This will actually be good for the car, because you will get all of the nasty oil that sits on the bottom of the pan. Before you put a new gasket on the oil pan, it's imperative to get all of the old gasket off. It is a PITA; You will need a good scraper. A gasket remover spray helps too.
