take out the oil pressure sender and install an 1/8 npt thread pressure gauge and see how it works
40psi idle to 65psi in high rpm but check with the specs to know exactly the correct psi
and what i think the problem you have is not the oil pump
need more info so i can tell you what is going onHow can i check oil pump in 92 mazda truck if going bad w/o taking off oilpan?
You can wet test the oil pressure. If it's within specs, the pump is fine.
If the oil pressure is low, it gets a bit more complicated. It might be the pump, or it might be excessive clearances or a leaking or blown out oil passage plug in the engine.
Regardless, the first step should be to simply test the oil pressure against the specification.
