If you don't hear knocking or ticking when the gauge doesn't go up, the oil pump is working. I would start by checking the oil sending unit. It is near the oil filter and sends a signal to the gauge. Make sure the connection is clean and tight and it isn't leaking. If everything looks good, chances are it is bad.
Let me know what you find or if you have other questions.
