2002 mitsubishi eclipse will not start on 2002 Mitsubishi Eclipse

I have a 2002 mitsubishi eclipse were I had the wiggle the key in order for the car to start after a week that car would not start. Changed the ignition key and the starter, the car still would not start. My husband and dad took the car apart and still found no problem. they then thought that it had to do with the computer. My father thinks that it has to do with the gas pump. My husband then ran it through the scanner and got the code P0001. I hope that you guys can tell me what could be wrong with the car
