Will start then shut off. fuel pump making loud noise and runs continuously with key off. Pressure does reach 50psi when starting but doesn't prime up when not turning over or running.

The first thing i would do is change out the fuel filter under the truck. Here is the location, also it sounds like the fuel pump relay is stuck so you should swap that out as well. Here are the locations of both. Check out the images (below). Please let us know what happens.
