Walbro 500hp fuel pump issue!!! need help plz

[BIG-EV]

hey there. just installed a new walbro 500hp intank fuel pump and now the bastard car wont start... After droping the tank and removing the cradel it sits in i installed a new pump and installed the new wiring (black to black, grey to blue) as this used to be a NA ecotec car. When i turn on the car it primes ect but car will just keep ticking over.. at first i thought it could be the hoses but far as i know they were put back on right... so just to make sure i wanted to see it it pumped, so i removed the hoses in the engine and see if any fuel umped out when it primed but none came out... thought it could b the wiring so i swaped the current around just in case it pumped the other way but still nothing.... Plz i need the car for work and its driving me NUTS!!!!!

check your wiring..its probably the other way around...the fuel pump is in reverse by the sounds of it...so its not sucking fuel ..its blowing..
