Do you have more than one zone? If so, it is difficult to tell if the circulator in question is actually running. A trick is to get a screwdriver and place the metal end on the front of the circ and the other on your ear. You will hear it if it is running. If you do hear it, is the circulator itself very hot to the touch? If it is, it may be burnt out, or the zone needs to be bled of air. Another doubtful, but possible, answer is that the circulator is installed backwards. There is an arrow on it and it should be aimed towards the flow of water.

SOURCE: After replace the cold water
Many times when pipes are worked on, the work loosens sediment that was built up in the pipe.
Sediment is probably why cold water line was replaced.
That's why faucet aerators get clogged up after pipes are worked on.
It sounds like your grundfos pump got clogged too.
Immediately unplug the pump so motor is not overheating.
Motors are meant to turn freely and can be damaged when blocked.
Take apart the pipes at grundfos pump and see if you can clean out the line.
If line cannot be cleaned or pump doesn't restart, then the grundfos has to be replaced.
Also look at adjoining pipes and see if there is a clog in nearby elbow, especially where galvanized and copper pipes join..

Sounds like you have sediment built up in the pipes, and maybe the furthest faucet is the gathering place.
Take off each shut-off valve at furthest faucet and connect a water hose that flows into nearby toilet bowl.
You can buy garden-hose-to-1/2-pipe adapter at hardware.
Open water so it flushes the line into toilet bowl.
Then clean out valves and reassemble shut-offs and grundfos connection.
Remove faucet aerator and flush line up to faucet.
Install new aerator.

SOURCE: Same problem as another writer
If the pump is hot, the motor has overheated and will stop working. There's no cure for motor at this point. Be sure to de-lime and de-scale re-circulation pumps occasionally.
Return pump and exchange for new. Sounds like you already diagnosed the problem correctly.
