If you checked it with a mechanical pump and that is the result, it sounds like a bad pump.


But is a new pump that mean I have to get the new pump like

I would recommend checking the oil pump. That would be my first guess based on your description. Other than that, you could have a worn out engine (bearings) that could cause the pressure to be low or even the pick-up tube on the oil pump could be plugged.


You mean take out the oil pump

If you have no pressure, you have to.


If the oil pump bad what is a good brand to buy?

I always try to stay with OEM parts.


I THINK J and N MEANT IN THE BEGINNING TO CHECK PRESSURE WITH A MECHANICAL GAUGE---SCREWED INTO THE HOLE THE SENDER IS IN NOW

(NOT CHECK IT WITH A "MECHANICAL PUMP" AS HE MISTAKENLY SAID)

I GOT MINE ON A PLASTIC TUBE----I CAN RUN IT UNDER THE HOOD OR THRU A HOLE IN MY FIREWALL

YOU CAN BUY A "UNDER DASH" UNIT AND USE IT TEMPORARY LIKE MINE----OR YOU COULD MOUNT IT PERMANENTLY (IF YOU GO THIS ROUTE--PICK OUT ONE YOU LIKE IT'S LOOKS!)

Yet that is I used screw in the oil sensor hold is read 60 psi from start and going down to 5 psi at idle about 10-15 min only when I raise up the rpm the pressure go down to 1 psi not up and stay there below 2 psi is look like a bad pump I just bought from the toyota dealer to replace it the old one
