Sounds like your battery is down, just because it's only 1-month old doesn't mean it's fully charged. Sometimes a battery will set on the shelf for a year before it's sold. Also, as stated, you could have an alternator problem.

Try jump starting it. If you get it running take it to AutoZone, etc, and have the battery and alternator checked for free.

If jump starting don't work, pull the battery and have it charged and checked.

Once you get it running then you can further check out the fuel pump problem.
