New Pump not working/priming JPSU-6P4.0

[Elwiscon]

Hello just replaced my fuel pump, i installed a crappy amazon one that pumped but the level sending unit crapped out, finally got the MTS JPSU-6P4.0 and had time to install today, Amazon pump was working when i took it out, i installed the JPSU-6P4.0 and to my dismay truck cranks but the pump isn’t pumping, as there’s no pressure on the fuel rail. I unplugged it, ran 12V directly to it and i can hear it running, i also checked for voltage at the undercarriage connector, ill disconnect the supply line to see if any gas comes out.  As far as i know these pumps are great. What could I have done wrong? There’s about 3 gallons of fuel in the tank so I don’t think it’s out of gas, any ideas? I’ll try to get back on it tomorrow, thanks.

When you turn the MJ to the on position but not crank, can you hear the fuel pump prime? If yes, then it sounds like the relay has failed. If not, something is wrong in the harness.
