You Mentioned in your first post that you used sealer in several places around the water pump, there is nowhere in that assembly that requires sealant, remove it all, clean it up really good , put it back together and try again. I suspect that the sealant is getting into places it shouldn’t be and stopping the water flow. Make very sure that the water tubes are fully engaged into the rubber grommets and that they are not crushed or torn. The thermostat engines run at 140f so there should be little water flow from the tell tale until it warms up and then the flow will increase dramatically but it will be hot so be careful.
