2.0 oil pump

Check the balance shaft belt - it also drives the oil pump and is known to lose teeth and cause oil pressure to drop or vanish. Check your timing belt also - it may need changed also.

I already changed all the belts when I replaced the water pump. I guess one of them could of broke. Things do happen. When I bought the truck the bs belt was already broken. It still ran and held oil pressure. Thanks for your knowledege.
