Crank no start it backfired once?

I just finished replacing the head gaskets and got everything back together got oil in it I don't have coolant in the motor yet. I just want to give you the background to bring you up to date LOL I went I charge the battery went cranking over Crank crank Crank but no start it backfired once. I noticed two vacuum lines sticking out one's black real small traced it back to the fuel pressure regulator I believe. The other is real small and white and it came out of a a bunch that I thought were wires and anyway it's stuck in there and It was just poking out I took pictures and marked them if you could tell me where this white vacuum hose supposed to end up where it started and if I'm correct about the black one it goes from a pressure regulator to the it looks like a fuel filter on the fuel rail on the other end. Appreciate the help I'll send pictures also
