Are both your heater hoses hot?

that hose doesn't go to the intake manifold.

one heater hose goes to the water pipe under the intake manifold, the other to the nipple on the transmission side of the head.

it actually appears none of your water hoses are hooked up correctly.

 

Have you check your Fuses?

 

Grab upper radiator hose and rev it a little ~ 3k if a surge is felt, your water pump is good. Sounds like a bad water pump to me though.
