Default 2004 WRX fuel issue

Hi everyone I could really use some advice here. I bought a 2004 Subaru wrx with a stage 2 tune that was partially gutted and used as a track car. I bought it at 102,000 miles and now Iím at 150,000 miles. Iíve had some problems along the way but nothing major.
Recently my car has been sounding odd when I drive it, kinda like itís congested or something, and then itíll randomly sound like itís supposed to like once or twice a month. I have an invidia exhaust I think. Anyways, due to it running weird I figured it was a fuel issue..... few months down the road and now the car isnít running. I was told it was definitely the fuel pump because at first the car just didnít want to stay running when I started it so I had to give it gas to keep the rpms high until I was actually driving. But when I was driving it was ok. Now today when I went to switch out the fuel pump itís not even priming. I tried both the new and the old pump and both turn when hooked directly to power, the harness that plugs into the pump has power when I turn the ignition. But when I put it all together no fuel gets to the motor because the pump isnít pumping. I was told it could be the controller or the relay but Iím clueless here and could really use some help.

Iím sorry for the novel here but Iím just trying to give all of the background information before I got to this point.

How many volts were you getting at the harness into the fuel pump?
