Could you help me with my respawn script c# 2d engine

Hi I'm having trouble respawning my player after he dies. It shows him die and the animation works fine but I can't get him to respawn afterwords. I have box colliders, both as colliders and as triggers, I even made the trigger colliders slightly bigger and still nothing happens. Any help would be appreciated. Here is my code for the death.

using UnityEngine; using System.Collections;

public class DeathScript : MonoBehaviour {

 void OnCollisionEnter2D(Collision2D collision){
     if (collision.gameObject.name == "Big_Asteroid" && collision.gameObject.name =="Medium_Asteroid") {
         Debug.LogError("HIT!!!!!!!!");
         StartCoroutine(DieAndRespawn());
     }
 }
 
 IEnumerator DieAndRespawn() {
     renderer.enabled = false;
     yield return new WaitForSeconds(2.0f);
     transform.position = new Vector3(0.0f, 0.0f, -5.0f);
     transform.rotation = Quaternion.identity;
     renderer.enabled = true;
 }

}
