Extruded clicking and no filament coming out

I’ve had my Ender 3-pro for less than a mont (I bought it used though.) and I’m having issues with the extruder; the filament won’t go through the nozzle and there are no clogs there’s a clack clack sound as the extruded tries to push the filament but it won’t, I just replaced both the gear and motor and it still doesn’t work. What should I do?
