93 Camry 5s-fe problem

Did you get that spray while you still had pressure or after the pressure dropped? Could a piece of something have worked its way up the passage to the oil filter? There is always a bypass valve, usually built into the filter, in case the filter becomes plugged. The thinking is unfiltered oil is better than no oil. But what if the passage is blocked before the oil ever gets to the filter? If that is what happened you should continue to get 0 psi each time you start the engine cold. Is that what's happening or do you get good pressure for one minute each time you start it?

Dandy news. Oil pressure is a good thing to have.
