No Oil Pressure ?

[Ron Roberts]

Since I had some concern about my main bearings being possibly bad, I purchaced an oil pressure guage. My oil light has not come on and it is working. I installed the sender and guage, turned the key, and the needle moved a tiny bit. Then I fired it up and the needle never climbed any higher. Basically 0 oil pressure. So I took a spin around the block thinking maybe it just needed time to fill up the sender or what ever it might need time for. Still no pressure. Any ideas? With the oil temp guage, if I disconnect a wire the needle pegs to the hot side. With the pressure guage if I disconect a wire it stays at 0. Is there any other test I might do.
I don't really want to face that I have no oil pressure

Thanks
Ron
