Always post year/engine for most accurate replies.
Generally speaking, start with replacing the oil pressure sending unit; also known in some parts stores as the oil pressure "switch".

I was under the impression the "switch" was installed on the other side of the engine for the dummy gauge. If it is installed where the sending unit goes, it pegs the gauge.
