If its showing no pressure you need to check the oil. If the oil is okay, remove the pan and check the oil pump. The same thing happened to me and my oil pump had fallen off

Check oil pressure with manual gauge, check when cold and see if pressure drops as it heats up to normal operating temperature, you may be due for a new engine at 240k miles
