Are you using a new water pump or an old one with many miles and years on it? Mopar water pumps have had a problem with impellers rotting off making them inept. So pull the pump and have a look….

Wouldn't "no circulation" imply a bad water pump or blockage some where?
Since you changed the t-stat, odds are it's not stuck, unless they were both Mr.Gasket t-stats.
You could/should change the water pump, and get an IR thermometer and trace the water flow, looking for a drastic change in temp or a reading that doesn't make sense.
