I have a 2001 suzuki oil pressure failure. Checked for oil pressure, reads 0. Less the 50 hrs on motor. Also tried a new filter, no luck there. Is htere any way to get break down on replacing oil pump or is the problem in the pressure regulator. I know to check the pickup screen. I have tried everything i know to avoid taking the power unit off, any suggestions you would have would be greatly appreciated. Thank You. BONEFISH
