Machine Gun Problems

Old issue: Machine gun stays disabled even when i press the fire1 button and doesn't shoot. Any help is appreciated.

So now here is the new issue... I can fire the first round however i can't fire after the first round because according to the inspector view it is not reloading. So here is my script

 using UnityEngine;
 using System.Collections;

 public class MachineGun : MonoBehaviour {

 public float range = 100.0F;
 public float fireRate = 0.05F;
 public float force = 10.0F;
 public float damage = 5.0F;
 public int bulletsPerClip = 40;
 public int clips = 20;
 public float reloadTime = 0.5F;
 public Renderer muzzleFlash;
 
 private int bulletsLeft = 0;
 private float nextFireTime = 0.0F;
 private int m_LastFrameShot = -1;
 
 void Start () {
     bulletsLeft = bulletsPerClip;
 }
 
 void LateUpdate()
 {
     if (muzzleFlash)
     {
         if (m_LastFrameShot == Time.frameCount)
         {
             muzzleFlash.transform.localRotation = Quaternion.AngleAxis(Random.Range(0, 359), Vector3.forward);
             muzzleFlash.enabled = true;
             
             if (audio) {
                 if (!audio.isPlaying)
                     audio.Play();
                 audio.loop = true;
             }    
         }
         else
         {
             muzzleFlash.enabled = false;
             
             enabled = false;
             if (audio)
             {
                 audio.loop = false;
             }
         }
     }
 }
 
 void Fire()
 {
     if(bulletsLeft == 0)
         return;
     if(Time.time - fireRate > nextFireTime)
         nextFireTime = Time.time - Time.deltaTime;
     while(nextFireTime < Time.time && bulletsLeft != 0)
     {
         FireOneShot();
         nextFireTime += fireRate;
     }
 }
 
 void FireOneShot()
 {
     Vector3 direction = transform.TransformDirection(Vector3.forward);
     RaycastHit hit;
     
     if(Physics.Raycast(transform.position, direction, out hit, range))
     {
         if(hit.rigidbody)
             hit.rigidbody.AddForceAtPosition(force * direction, hit.point);
             
         hit.collider.SendMessageUpwards("ApplyDamage", damage, SendMessageOptions.DontRequireReceiver);
     }
     
     bulletsLeft--;
     
     m_LastFrameShot = Time.frameCount;
     enabled = true;
     
     if(bulletsLeft >= 0)
         Reload();
 }
 
 IEnumerator Reload()
 {
     yield return new WaitForSeconds(reloadTime);
     
     if(clips > 0)
     {
         clips --;
         bulletsLeft = bulletsPerClip;
     }
 }
 
 int GetBulletsLeft()
 {
     return bulletsLeft;
 }
 }

so there is no errors and now i have a BroadcastMessage("Fire") on another script so thats not a problem anymore... so any help is appreciated.
