Re: Oil pressure switch
How many wires on the oil pressure sensor?
Oil pressure switch will NOT cause the car to stall. It is a backup power source for the pump in case the relay fails. That's it. Otherwise, your car would NEVER start until you cranked it long enough for oil pressure to come up.

Switch is a backup for the relay as stated above.
Neither will prevent your engine from running.
