Dusty,

I would check the oil pressure with a gage that you know is good.

Run the engine as little as possible to do this.

If the good gage reads also no oil pressure I would start by checking for any oil leaks in any of the external oil lines. Probably a leak bad enough to cause the no oil pressure problem would dump a lot of oil on the ground. If no leaks are found, check the oil pump. It isn't likely to be the oil filter, they are designed to pypass if they get plugged.

Whatever you do, don't drive the car before you have oil pressure. If it has to go to a garage, tow it there. Running without without oil can damage the engine bearings and rings in a hurry. A complete overhaul or rebuilt engine would then be required:$$$$$$$$$$$$$$$$$$$$.
