Sprite is not shown moving

Alright, so I asked this question earlier, but I made some new discoveries about it that I think constitute a new question. I have a sprite that I am trying to move across the screen. Here is the script:

 void Start()
     {
        database = GameObject.Find("DataBase");
        if (database == null )
        {
            Debug.Log("DataBase not Found");
        }
        data dat = database.GetComponent<data>();
        direction = dat.direct;
        north = dat.NW.y;
        west = dat.NW.x;
        south = dat.SE.y;
        east = dat.SE.x;
     }
     // Update is called once per frame
     void FixedUpdate()
     {
         while (alive)
         {
             transform.position += direction * speed * Time.deltaTime;
             if (transform.position.x <= west || transform.position.x >= east)
             {
                 alive = false;
             }
             if (transform.position.y >= north || transform.position.y <= south)
             {
                 alive = false;
             }
             Debug.Log("Transform Position: " + transform.position);        
         }
         if (Input.GetButton("Jump"))
         {
             transform.position = new Vector3(11.0f, 0, 0);
             alive = true;
         }
     }

The North South East and West are values which coordinate to the edges of the screen.

With the speed set to 0.1 on start the sprite will remain still for about 3 seconds before it "teleports" to the edge of the screen. My Debug.Log shows nothing in these 3 seconds, but when it teleports the console instantly shows 999+ debug messages claiming that the sprite was moving across the screen the entire time. The inspector shows no sign of the transform position changing at all apart from the starting point and the end point at the edge of the screen that it teleports to. I just don't understand what could be wrong. Any help would be appreciated.
