Start by charging the battery completely. Then, start your car and while running, remove the NEGATIVE battery cable from the battery. If the car dies, your alternator is bad. If it keeps running, reinstall the battery cable and turn the car off. Check for something that's on that would drain your battery like a light in the trunk, glove box, etc. that wont shut off.

vacuum leaks, air filter clogged, idle control system, or leaking egr, leaking head gasket, worn timing chain, camshaft lobes worn, valves burnt or leaking, faulty emissions or engine control system.
