Coupe or Sedan?
440 General Evap System Failure
441 Purge System Performance
You have a HUGE leak somewhere, the NVLD pump itself is not working or one of the Purge Solenoid hoses is off. My bet is the canister line from the purge valve is split somewhere. You get those 2 codes when the PCM can't initiate the EVAP test.
Check also and make sure the purge valve hoses are not switched around backwards.
