It's located to the rear part of the oil pan. To change it, the oil pan needs to be removed. To do this, the engine needs to be raised, or the transmission needs to be removed. Make sure it is the problem before just "changing" it.

if what you say is true and you have the correct voltage..12v to the pump, then the pump you install is bad or it has a faulty ground wire in the system.

If the oil gauge is not moving making you think it's the oil pump, change the oil sending unit, that will cause a no reading. If it still doesn't register, than the oil pump is bad.

Gas in oil


Ok, only two ways the oil can mix with the gas. one is a blown head gaskets. the other would be bad piston rings.

I have a 1986 nissan 300zx non turbo. oil prssure will not build up. keep addin oil but all its doing is smoking out the exhaust. acts like the strainer on the fuel pump might be stopped up. can i clean...


Dear number601513: DANGER!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Adding oil is not going to make the oil pressure build up by adding more. The system is slightly more than a 4 qt system with an oil filter change. By adding oil, you raise the levels in the engine to areas where it is not designed to collect. Consequently, it is prone to leaking and can smoke by picking up oil through the pcv.
The fuel pump has NO relationship to it's oil pressure. The only relationship would be through providing enough fuel to power the engine speed above 600 RPM which would and should be more than adequate speed to drive the oil pump. The oil pump on the VG-30 is located at the front of the engine and is the last component which is installed prior to to installing the timing belt gear. The pump is crank shaft driven, so it is a positive drive unit and not very prone to failure. The oil pickup tube which is bolted to the bottom of the pump, is sealed by an "O" ring. This is a probable place for it to loose prime. The screen at the bottom of the pick up tube could be full of sludge which limits the flow of oil, thus keeping the oil pressure dangerously low. One suggestion prior to condemning the engine oil pressure, is to do a mechanical oil pressure test. You can remove the oil pressure sending unit and screw a mechanical oil pressure guage in it's place. The threads are not metric, but NPT tapered design. You can buy mechanical oil pressure gauge kits relitavely cheap and make a test tool with one. Due to the fact that the oil pressure gauge is electric, they can give misleading readings. If your readings are down in the 8-10 PSI area @ idle this is bare minimum, when you raise the engine speed, the oil pressure should reach 40-60 PSI. Make sure you bleed the air out ot the oil line going to the gauge beause "AIR" compresses and will give you a false reading.
I hope this is informative. Good luck.
