2000 Pontiac Sunfire Evap vent solenoid

Hey, my 2000 sunfire 2.2l wont start i figured it was the fuel pump the batterys good and i just replaced the starter. So i listened for the pump and i can hear it running when i turned the key, when i took off the fuel filter there was no fuel pumped when i cycled the key. I checked the relays, fuses, rotor and cap, etc. i went to install the pump and unpluged connections to the C313 connector and i noticed the evap vent solenoid connections wires going to the powertrain control module had ripped apart would that cause my car not to start? Im scepticle because i hear the pump run snd im not sure what this evap vent does. Im a college student and really dont have the money to put in a 300$ pump i dont need! Thanks:)
