Player Respawn Problem, Bullets dont move! [C#]

Hi I have aproblem! Everytime my player respawns and tries to shoot, the bullets dont move, they appear in position 0, 0, 0. What im doing wrong? Also Sorry for the bad english. Here’s the code im using:

 public class MoveTrail : MonoBehaviour 
 {
     public float maxSpeed = 40f;
     PlatformerCharacter2D platformerCharacter2D;
     Vector3 pos;
     Vector3 velocity;
         float nextTimeToSearch = 0;
     //---------------------------------------------------------------------------------------------------
     void Awake()
     {
         platformerCharacter2D = GameObject.Find("Player").GetComponent<PlatformerCharacter2D>();
         velocity = new Vector3(maxSpeed * Time.deltaTime, 0, 0);
         pos = transform.position;
     }
 
     //---------------------------------------------------------------------------------------------------
    
     void Start()
     {
         
         if (platformerCharacter2D.m_FacingRight == true)
         {
             velocity = new Vector3(maxSpeed * 1 * Time.deltaTime, 0, 0);
         }
 
         else
         {
             velocity = new Vector3(maxSpeed * -1 * Time.deltaTime, 0, 0);
 
         }
         
     }
 
     //---------------------------------------------------------------------------------------------------
     void Update()
     {
         pos += velocity;
         transform.position = pos;
         Destroy(gameObject, 1);
     }
 }
