Question about GMC G3500

More than likely (and we will hope) it is the oil sending unit. In comparison it is a very cheap and quick fix to replacing the oil pump. Auto Zone has a pretty good componet location section that has tips for replacement if you cant find the sending unit or the oil pump. Try that first it may save you a lot of work.

Stop driving it now! Have someone check the actual oil pressure with a manual gauge, which will be installed where the oil pressure sender normally goes. You may have a problem with the gauge circuit, but you may have no oil pressure, which will destroy your engine. Don't take that chance. Get it checked out!
