No, the exile has no force connection. None. He had none while he was in exile, and he has none during the game. So why can he use the force during the game? Because he forms new bonds with his companions and can "feel" and manipulate the force through those - note how it's described as being "somehow far way" or "from across a great chasm" or "like an echo" the first time he feels the force again. That's because he has no direct connection - he has a connection only through a bond with Kreia at that point, which is the "distance" mentioned, as he gets the force "second-hand", if you will.
So why didn't the exile do that during his decade in exile in the outer rim? That's what HK-47 tells us - he simply disconnected himself from other people, and without a bond to other people he has no access to the force.
The exile is, of course, completely oblivious about this throughout most of the game.
Exactly, Exile never had an existing force level coursing through him. However after Kreia's death he is connected to the force why? Because he most likely receives most of her's... Or he just is granted it back.
