You have an air lock, bleed the air from the cooling system,
hot water not air will allow the stat to open
do this by loosening hose to remove air, then start engine

OK One Fan is for the A/C Condenser, Does it come on when you turn on the A/C? If not you may have inadvertently shorted the wiring when Replacing the Pump. Radiator fan most likely is the Thermostat! Sensor the Signals the Relay to Cycle the fan works only with the Thermostat Open and Coolant is Flowing. Good Radiator Shop if you're not sure how to Repair the System. Cooling Systems on the %26quot;NorStar Engines%26quot; are Good (In most cases Better) but Difficult to handle some times.
you have an air pocket in the system as bustass says,but do not remove the hose,just remove the cap l;et run to operating temp with the heat on and the fan speed on high,let run till cooling fans cycle you will see the system burp,also squeeze the upper radiator hose a couple of times while the cap is off.once all the air is out you can refill the coolant to the hot level,replace the cap and your good to go.
Make sure you got the right water pump
depending on the options for you car, the belt may route a different way which sometimes turns the water pump backwards!!!
Sound crazy but I've seen it before
Similar pumps may fit the engine but it's internal fins maybe wrong for your application
Yes
sounds like it, it is easier to change the thermostat, and see if that works than redoing the waterpump
Good Luck!
