Unhappy 5.0 not starting

ok so i know that im
jumping the gun here, since i haven't checked anything but my 5.0 failed to start today. i went to turn it on after about a month of no activity (stupid i know). it cranked but wouldn't turn over. my first guess is battery but it's only about three months old.
what worries me is that there's a loud clicking noise coming from the engine. kind of like when your battery is dead but much louder and with a smaller frequency. any thoughts or ideas?

Sounds like the battery to me....if its just clicking....there might be a draw on the battery if you have not used the car in a month...charge the battery & check it with a multi-meter if you have one....

...Also check your ground & make sure the starter has power wire bolted good (Disconnect the Battery FIRST!)

wiggle the negative battery cable, then try again.
