New fuel pump no start

So I just installed a new bosch fuel pump. I can hear it go on when I turn the key but I'm getting nothing at the rail. I have rechecked connections and dropped the tank again once. I did have about .5 gallon to a gallon in there. Should I try to put more gas in maybe the pump needs some more?
Need some fast help
Thanks

Yes, put in a couple gallons of gas and try again.
