        Maybe not so weird if He did indeed not do reconnect that Mark discussed ~

Once the Eng' is running the Alt' will provide 12-14VDC needed to keep all Happy ~

So if I got it correctly, you have a no start and no fuel pump relay power at key on, but if you hot wire the fuel pump you have a engine start and after that engine start, when hot wire removed, engine runs correctly.  If that's the case, it's really strange.  Relay not working correctly??  Have you checked power at the relay as well as the fuel pump at key on?  Any listees familiar with the operation of that relay and if it's a different circuit for start and run?
