Extruder pulley does not turn during calibration or printing - turns OK only when loading and unloading filament
Following a filament runout event, the extruder pulley only turns when inserting or withdrawing filament. I've replaced the nozzle, heatbreak, & PTFE tube. The filament extrudes nicely during the initial Load Filament stage, and the pulley works when unloading the filament also. During first layer calibration The pulley is definitely not turning at all, and the PLA filament only seeps out of the nozzle under the heat.

Ok, pulley is not turning.. but does the extruder motor shaft rotate? If yes, then you need to check if pulley is properly fixed on motor shaft (one grub screw must be tightened on shaft flatness).

the shaft and pulley are tight and will only turn at load or unload filament

Could a filament sensor malfunction cause this?

Is the extruder temperature above 170c. This is the low temperature extrusion limit

Any clicking sound? Maybe a video may help diagnose it.
