Hi I'm Wayne

I will help you with this

when the oil pressure drops too low

the switch opens and cuts power to the

fuel shut off solenoid , you may have a bad sensor (OIL)

or you have low oil pressure

I hope this helped you

what do you recommend?
Expert:  Wayne replied 2 months ago.

HI

I suggest to remove the oil pressure switch , screw in a manual oil gauge

and run and check the pressure, as long as it stays above 20 Lbs, replace the sensor

I hope this helped you
