Missing Fuel Pressure! Where did it go? OBS Chevy k1500 Truck

In this video we are working on a 1999 old body style Chevrolet k1500 pickup truck. It's been sitting for about 2 years and now it's time to give it a new home. But first it needs to run! It will run when fuel is put directly down the throttle body, but it quickly dies. I originally thought the fuel pump failed (like what happens to every other old truck). Turned out to have an entirely different issue. Check out the video to see what we found!
