Hi there

The code is for a large evap leak. If it's got trouble starting after you fill it it's normally a bad purge control valve. If it's stuck open it will cause the code because it is a large evap leak. It also causes the hard start because the fuel vapors go into the engine and basically flood the engine.  I wold start with the purge control solenoid valve.
