I had the same issue on my F. Decided to pull the pan to check the screen, since the car had been sitting for 12 years. Screen was clean, oil pump was not seized. I could not see any issue with the pressure relief valve. Pump had some scoring but looked OK. I replaced the oil pump, everything worked fine. New oil pump was relatively inexpensive over at Napa auto parts and very easy to replace. I did run the oil pump with a long allen wrench and drill to prime everything before starting.

Standard engine and runs terrific. Had it aligned yesterday and on the way home the bright red no oil pressure light comes on. Check of the dip stick shows full of brand new oil, the same I put in months ago so I'm guessing bad sender and drive two miles home. Today I remove the valve covers and find a spotlessly clean rocker set up and all 16 pushrods pushing and all 16 rockers rocking. This lets out a stuck valve and a bent or missing pushrod. and/or popped out tappet All the rockers are starting to sound noisy. I remove the sender and crank the engine. No oil shoots out.. Is it likely that an oil pump failed? Do I need to remove the oil pan and check the pickup and strainer? Messy and hateful job. Some of you may suggest I contact the 1966 300 Consultant of the Inc. Club, but that is me and I already checked with me. Now checking with you.
