Agree that looking for blockages is a good next step, I should have mentioned that. Luckily the oil feed path to the engine is short. You can disconnect each hose to double check them. And then at the engine, a visual inspection as you suggest and use a light and/or compressed air to check for restrictions like a piece of a rag, etc. that could get sucked into a blind passage. Basically just follow the path from the tank to the oil pressure sender.
