I would suggest getting the new oil pressure switch it require a special socket it just twist off
few turns and its out
you can try deep sockets on the new switch if dont have the special socket
you need to know engine size at the part store
it should be priced under $20
for you to test oil pressure
you need a set of special gauges remove oil pressure switch
install in its place and start and drive the car watch oil pressure
