This problem has nothing to do with electrical connections it has to do with fuel vapor pressure leaking. First thing would be to insure gas cap had a good.gasket seal.
Anything happen that might have disturbed something related to vapor pressure. A disturbed fuel pump gasket?

Let me check what I posted on top (and edit if I need to). I don't recall saying that the code was related to burned connector. The burned connector melted the plastic and the vapor leak is the issue (just as you stated).
Thanks for clarifying.
here are the possible causes I listed, maybe you have overlooked them:
Possible Causes (as listed on the web):
- Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
