Replaced fuel line now car wont start

[Distrut31]

So i replaced a section of fuel line on my 2009 chevy cobalt ls. I did not have to depressurize the fuel line since it had such a large hole in it. I replaced a 4 foot section with high pressure hose and now the car will not start. Here is everything that i have done. Trued repressurizing the fuel system by turning the key on a few times before trying to start it, i have pulled the fuel line from the fuel rail to check if it was getting fuel and its not, i have blown compressed air through the old part of the line to make sure it was not clogged, i nevered pulled the fuel relay so its in correctly, there is some fuel in the line because i can seperate the old and new line and gas will come out. I am out of ideas of what it could be other than it throwing a low pressure code from the fuel pump. Any ideas would be really appreciated. Thanks
