If you've done all of that then it means the engine is just worn out. For most of these engines is the oring on the pickup tube. Sometimes there is a screen below the oil sensor that can get stopped up and give a false reading. Has that been checked?

    Was running fine and then the oil pressure low alarm went off and the pressure dropped to zero. We changed the pump, pick up tube, all gaskets, oil sensor and oil. It's still alarming. Any ideas?
