Zero Fuel Pressure, Newish Fuel pump

I bought my car about 5 years ago and had a new gas tank and fuel pump installed 4 years ago. Around 2.5 to 3 years ago my injectors fried themselves so I replace them and at the same time the in line fuel filter. Two weeks ago when I got back from college, my car would barely start and stall as soon as I pressed the gas pedal. I pushed it up onto wheel ramps and rented a fuel pressure gauge from Autozone and the gauge is showing zero pressure when the key is in accessories and when I turn the starter. I pulled up the carpet in the back to look at the fuel pump (the floor hole was there when I bought the car don't kill me) and when the key is turned I audibly hear the pump running so I know that it's at least receiving power. I'm confused as to where I'm losing all of my pressure because the gauge doesn't even shift a little, so any help/ideas would be appreciated.

Do you have enough gas in it?
