Why Is My Oil Pressure Gauge Still Saying 20 And Going To 0 When Stopping ?

I had to change my oil sending unit switch and afterwards I had 60 oil pressure on my gauge but not long after driving it went back down to 20 and when I stopped it went to 0 and my check gauge light came on, but the dipstick said full. Within 3 days I changed sending unit 2 times and I still have the same problem. I am not leaking any oil though when I first changed sending unit because it went bad I leaked oil everywhere and lost all oil. It came out of the sending unit. Now I have no oil leaks but still having the pressure problem. I am getting ready to do a oil change even though I changed filter when I changed the sending unit the first time (2 days ago). Can someone tell me what is going on and what to do???? please

  • IS IT POSSIBLE THAT WHEN THE FIRST SENDING UNIT WENT BAD AND BLEW OIL EVERYWHERE UNDER THE HOOD THAT IT COULD HAVE MESSED WITH THE ELECTRICAL THEREFORE THE GAUSE SO SOMETHING DOESN'T KNOW THERE IS A NEW SENDING UNIT ON THERE . DO YOU KNOW WHAT I AM TRYING TO SAY?
