Default Oil Pump reading Zero at startup, then goes up. Is this normal?

Hi guys,

I started my car yesterday and noticed I had a check guages light on. I checked all my guages and it looked like I had zero oil pressur. Just as I went to turn off the car the oil pressure returned to normal. There were no strange noises (that I would associate with no oil pressure), the car drove fine and maintained pressure the whole. I noticed it did the exact same thing this morning when I started up; you guys think I need a new oil pump or it is probably just the guage.

Sounds like a sending unit issue to me.

Well I normally wouldn't mind, I'm selling the car very soon so I don't want the pump to crap out. Would a sending unit issue be in the PCM? It's not throwing any codes.

The sending unit is a sensor type piece that sits right behind the intake manifold. It looks like a standing roll of pennies in shape.
