94 GLS Won't Start

We just recently replaced both the starter and the Mass Airflow Sensor on our 94 Jetta GLS. It worked fine for a day and now it won't start. It won't even try to turn over. There is just a faint click when we try to start it, but nothing else. Its not the starter, we thought they sold us a bad one so we warrantied it out for a new one and it didn't do anything. Anyway, if anyone can help please post asap!

Have you try putting a jump box on your Battery and trying to start the car? You might have a dead battery. Dose any of your lights on the dash come on when you turn the key on?
