: Oil pressure switch and connector?

83 Deville 4.1? My oil pressure switch connector was not connected and the wires were wrapped around each other. I think this was done to make the car think it was connected. Once i changed the switch and the connector the car has been acting up. The idle is up and down and it cuts off.

Now it won't start at all!

Replace the sender with a gauge to see the actual oil pressure. If the oil pressure is too low, the pressure switch turns off the fuel pump.

Try disconnecting the battery?
