Sounds like you have a fuel leak somewhere you can add a leak dye to your gas tank then use a dye light to trace the leak to its source. The first thing I would do is look for a leak visually if nothing found that way then add the dye.

The P0440 is the only code I see that could be related to the smell. Check all you evap lines for cracks breaks or being disconnected.
