the engine gets hot and while your engine is running your oil is going through your engine lubbing it. by the time the engine gets hot the oil is spread throughout the engine. if you have too much oil in the gauge will act weird because its hooked up to your oil to read its pressure. if it was youroil pump or switch it would do this when the engine was cold to. make sure the oil is at the correct level b4 spending money on a switch or pummp

Yes it can. Instead of an inertia switch, GM ran the fuel pump through the oil pressure switch. If the engine quits running and loses oil pressure but the key is still on, like say in an accident, the fuel pump is shut off as a safety precaution.

What is an engine oil pressure switch?
When the engine is running in your car the pressure of the oil activates a switch that is fitted along the oil line. this switch turns of a light that would otherwise be on on the dash of your car whenever the ignition is turned on. If your oil pressure goes down because you are low on oil or because your oil pump is not working properly the light on the dash turn on intermittently or stays on.
