Answer
Simone,
  Please note I'm a Parts Professional, NOT a Tech. Okay?? I will give you my thoughts but make NO claim to be able to answer your question. Here are my thoughts...
  If you can jump the car, it sounds like the charging system is failing. The "machine gun" noise you are hearing is the starter solenoid, I believe. Not seeing the car, it is difficult to diagnose. I would do this:
  Remove the battery and take it your local parts store to have it checked out. If it is low, it will need to be charged before they can test it. It may take a few hours to charge so be patient. IF it tests good, install it but leave the + cable off and remove the alternator and have them test it. While you are removing and installing, look at the connections to make sure they are clean. IF the alternator tests good, look closely at the belt to make sure it is not slipping.
  Install the + cable. If none of the above help, there must be a problem with a wire or connection somewhere. NO ONE will be able to tell you where, you will just have to trace the wires until you find the culprit.
  Simone, I'm sorry but this is the best I can offer. Again, I'm a Parts Pro, NOT a Tech. Good luck, brother...
