The pump sends the oil up to the main bearings of the crankshaft (in the lower middle), which converts linear energy into rotational energy. From there, the oil moves through oil holes drilled in the crankshaft, to the rod bearings, and then through an oil line to the cylinder head (in the upper middle).
The engine oil pressure warning light will come on if the engine oil pressure is low, or if the oil pressure sensor is faulty. In either case, engine power may be reduced significantly. The check engine light may also illuminate, and an on-board diagnostic (OBD) trouble code will be stored in the vehicle’s computer.
Maybe you’ve noticed higher engine temps, and a new, louder clattering under the hood. Unfortunately, signs are pointing to an oil pump replacement — and the sooner, the better. Fortunately, parts are affordable, it’s a straightforward task if you have some time, and the DIY method can save you hundreds of dollars.
What are the signs of a weak oil pump?
A look at the three main signs that you need to fix or change your oil pump: low oil pressure, high engine temperature, and noise.
Common Oil Pump Failure Symptoms

Increased engine operating temperature.
Noise.

What does an oil pump sound like when it’s going out?

What causes oil not to pump?
Engine Wear
If the oil level on the dipstick is between “add” and “full,” a possible cause of low pressure would be worn engine bearings, especially if the engine has very high mileage. Excessive wear reduces the original flow restriction, which consequently drops the pressure.
What causes a pump not to prime?
Debris blocking the suction strainer or foot valve is the most common cause. A blockage in the intake line can cause the water in the pump casing to overheat and literally boil out of the casing causing the pump to lose prime.
If you turn on the tap at your kitchen sink and no water comes out of the spout, your pump may have lost its prime. Check to ensure your pump’s circuit breaker hasn’t tripped and caused the well to lose power.

Which pump must always be prime?
In short, to avoid failures, centrifugal pumps must always be primed before operating. Positive displacement pumps are self-priming with suction lift capability, but always check the operation manual or confer with an engineer to ensure the pump will properly function at start up without priming first.
