First time out it ran great for a couple minutes, then would only idle. Temp light flashed and I noticed not water pumping out at all. Blew through the tubes on both ends and doesn't appear to have any clogs. Where do I start??? Any suggestions.
Don't check it with air, check it with water such as a garden hose while you engine is running. If the water doesn't come out of your exhaust, pee hole on the side and jet nozzle, then you have a blockage somewhere.
