Hello, yes the check valve is in the fuel pump assembly. The check valve is leaking and the pump will burn out soon. Unfortunately the aftermarket fuel pumps can be very unreliable. A good portion of problems we see on this site are from people who replace the pump sometimes twice and it still doesn't work.

replace your MAP sensor(manifold absolute pressure) the map sensor is the computer for your fuel pressure regulator telling how much pressure. Unless your tahoe runs like **** going up hill than it inevitably your fuel pump

are you using the original key ?? sounds wear but in the key switch there is a sensor that detects if the right key is in use otherwise it will kill the power to the fuel pump or it can be a fuse look under the left rear passanger seat there is another set of fuses and the other set of fuses are on the driver side near the door and there is another set of fuses and relays inside the hook next to the battery
