2002 mitsubishi lancer oz rally edition

Why wont my new feul pump work? All relays and fuses work. I wired it direct to the battery and the pump turns on and so does the car but only for a few seconds. I did smell burned plastic when it went out. My battery is dead but i used jumper cables to try it all out. Could this be just a battery issue, or is the wiring,or something else?
