There are many things to try before force feeding.
So is his 2 weeks old and has never ate?
Can you describe your setup (enclosure size, substrate, temps etc)?
Now if your setup is not what I am about to recommend I encourage you to follow this.
Get a 6 quart tub, use aspen bedding, have a small hide (6 inches plastic flowerpot saucer) a water dish and leave your animal alone for a week (NO handling) once a week has passed offer a live hopper mouse.

Depending on the health I would never consider assisting an hatchling that is not eating before he is at least 4 to 6 weeks.
Again many things to try before coming down to that.
