Default No start after Racetronix fuel pump swap

Seeing if you guys can help me out here. Car ran perfect before I did the swap. I just wanted to upgrade from the stock pump and put in the Racetronix hotwire kit. I did the trap-door method for easier access.

So now....when I turn on the ignition I can hear the pump priming but the engine will keep turning over and won't start. I removed the schrader valve on the fuel rail to see if I was getting fuel, and nothing. I removed the fuel feed line connection from the sending unit area and tried starting it, again no fuel.

It seems like the pump isn't feeding fuel, but I can hear it prime when I turn the ignition. What might be wrong? Faulty fuel pump?

Ok thanks, I'll check it out. If I remember correctly I didn't mess with the red/black wires on the fuel pump harness, just added the purple wires from the sending unit.
