I have a 92 pro v 150 that i just fired up for the first time since winterizing. I check the water pressure guage and at idle it was 0 psi. I was getting a stream out of the pee hole within a few minutes the alarm sounded. I let it cool down ran it again with garden hose and removed the hose at the top of the cylinder head that goes to pressure guage. with water coming out of the pee hole there was nothing at the top of the cylinder head unless i goosed the motor. Any ideas I removed the pump looks ok but I really dont know what to look for there as i am a automotive mechanic . when i winterized it i checked that poppet to see if any debree and found nothing maybe i put something back together there wrong but dont beleive I did any help here is greatly appreciated
