I WAS DRIVING TO WORK YESTERDAY AND NOTICED THE OIL PRESSURE GUAGE WAS STUCK AT 120 LBS, WHEN YOU TURN THE CAR OFF IT GOES BACK TO 0, BUT WHEN YOU CRANK IT, IT GOES TO 120? ANY SUGGESTIONS WHAT HAPPENED.

Wiring/ground problem maybe. May be the oil sending unit is bad. Can hook up an external gauge and see whet the pressure really is to be sure it is good.
