Pre-start oil pump for car engine?

You could wire up an oil pressure switch to the engine coil... Then the engine would crank until the pressure switch left the coil fire... Also if for some reason you lost oil pressure the engine would automatically shut down...

Maybe an unintentional benefit of a lawn tractor (or other equipment) engine that has low oil shutdown. No oil pressure, no ignition.

Had a problem with that on an '85 Ford Ranger. Wired the heat riser damper permanently closed to always draw manifold heat, and it never bothered me again. --Glenn Lyford

Accusump is 100% mechanical, and has saved many expensive racing engines for decades. Just close of the valve before shutting the motor off. When you restart, open the valve a few seconds before cranking so the pressurized oil can flow into the oil passages. Then start the motor Rex in Fort Worth
