First, check if there is coolant circulation
As fare as I know, an easy way to know if there is flow or not is to put your heater to full warm with the car running. If you don't get heat inside, there is no flow.
Like Bill said, if there is no air trapped inside the system, you probably have a bad pump or the system is clogged with something.
When did you change the pump?
If your pump is bad, you won't have any circulation and the upper hose will be quite warm and the lower one will be a lot cooler and both fans won't come on as the rad is too cool to triger the switch.
Been there last spring.
And, if you have to go to the pump again, it is a lot faster and easier the second time!
At the pump, first thing to look at is if the paint marks are still aligned. If they are, the pump is good. If one (or two) is not aligned, something wrong with the pump.
This photo is about one year old so not sure if the paint marks are still the same.
Good luck.

I have been in contact with Ed, who advised me to check the same thing. The marks are all still Aligned. I cranked the engine to see if they would slip, but they remained in line. I suppose this must mean that somehow the repair shop plugged the radiator.

So the pump worked as designed and didn't lock up? The engine guard system is a success?

thats great that you found the issue .. the next question is why did the pump fail?
Is the connection rubber too weak or
was the heat from losing all of the coolant the cause?

Thomas:
You should have bought a spare rubber piece with Ed's pump. These are wear items. Easy fix. Stan may be onto something with his question as to whether engine overheating did this. I didn't think your overheating was serious enough to cause any problems, but perhaps the rubber piece in Ed's WP is sensitive to heat, softened and failed, even without a significant resistance increase. Too bad.
