What are the two types of oil pumps?

There are two primary types of oil pump used in automotive wet-sump systems: The gear pump and the gear-rotor pump. Most American engines designed prior to the 1990s use gear-type pumps, with two spur-type gears mounted inside an enclosed housing.

Why does my oil pressure drop when I stop?

Low oil pressure at idle only, will most often mean that the engine is low on oil. As more power is applied to the engine via acceleration, the pressure builds up inside the engine. … High oil temperature can cause low oil pressure. A defective oil pump can also lead to low oil pressure at idle.

Can a bad oil pressure sensor cause a no start?

The oil pressure sensor on some models may prevent your car from starting if it isn’t working correctly. … If it sends a signal that the pressure is low, the computer may prevent the engine from starting.
