Problem with startcoroutine

I have a Porblem. I try to recreate the 2D roghlike game. My Enemys and the Player arent moving.
The Problem is in the Coroutine. The Log1 is Displayed, but Log 2 isnt.
Code:

Code (CSharp):

1. void Update()
2.     {
3.         if (playersTurn || enemiesMoving)
4.             return;
5.         StartCoroutine(MoveEnemies());
6.         Debug.Log("Log1");
7.  
8.     }
9. IEnumerator MoveEnemies()
10.     {
11.         enemiesMoving = true;
12.         yield return new WaitForSeconds(turnDelay);
13.         if (enemies.Count == 0)
14.         {
15.             yield return new WaitForSeconds(turnDelay);
16.         }
17.  
18.         for (int i = 0; i < enemies.Count; i++)
19.         {
20.             enemies[i].MoveEnemy();
21.             Debug.Log("2");
22.             yield return new WaitForSeconds(enemies[i].moveTime);
23.         }
24.  
25.         playersTurn = true;
26.         enemiesMoving = false;
27.  
28.     }
29.     public void MoveEnemy()
30.     {
31.         int xDir = 0;
32.         int yDir = 0;
33.  
34.         if (Mathf.Abs(target.position.x - transform.position.x) < float.Epsilon)
35.             yDir = target.position.y > transform.position.y ? 1 : -1;
36.         else
37.             xDir = target.position.x > transform.position.x ? 1 : -1;
38.  
39.         AttemptMove<Player>(xDir, yDir);
40.     }
41.  
42.  

 

Do not start coroutines every frame; this will just endlessly create/restart them.

 

It doesnt start when Enemiesmoving = true. And at the start of the Coroutine, its set to true and at the end to false. Shouldnt this work?
