Does your heater work? It sounds like you have the same setup as the original poster, and I just can't see how that would work.
Most all hose connections on the water pump are INLET connections, meaning water is supposed to flow IN to them, not out. The outlet side of the water pump is the engine block. So you have an inlet connected to an inlet, there is very little pressure difference there to create flow.
And it begs the next question, how does your intake manifold not have a spot for a nipple? I have a couple on mine.
I suppose if you're really desparate to fix it without replacing the entire intake manifold, you could always get a new thermostat housing with a spot for a nipple. It's certainly not the best, because you won't get any flow or heat until after the thermostat opens up, but it would be a cheap solution.
