Sadly, could be a number of things but the error code is as good of a place to start as any other.
14 doesn't have a lot of internet hits but what I did see said to check the vacuum hoses in and around the intake manifold. Might have to remove the air cleaner to get a better view. Look for one missing, pinched/kinked or torn.
As for the fuel pump not running, under the seat and next to the main fuse box is a small white covered one that houses the fuel pump fuse and a spare. Pull it and make sure the fuse is good. If bad swap with spare and see if problem goes away. That said, fuses don't blow for no reason so problem might reoccur...
No starts with good cranking are usually fuel or ignition. If you know how, test each independently and then zero in on what seems to be wrong.
Silly question but you do have gas and the petcock is open right...?? Air filter is clean or new.
And the 100,000 question: Have you done anything recently to the bike? Even things that seem totally unrelated are worth posting because you never know but if one of us has caused X when working on Y we'll generally tell you
