With the facts you’ve provided, I can only guess.
So here goes
1 - Can you push your filament through the hot extruder by hand?
2 - Does your filament fit into your Bowden tube?
3 - Do you have good tightness between your pressure roller and the Hobb-Goblin teeth?
Sometimes PLA gets pretty stiff as the roll of filament gets smaller.
That stiffness can cause exactly the trouble you are speaking of.
Try a new spool of PLA or warm the PLA up to about 30 degrees C
To get better suggestions, I would say following information would help others to be able to help you.
Type or model of printer?
Slicing software?
Photo’s of your setup?
…
Just some thoughts
