My truck will not start. You can pour gas in the intake and it will run until the gas runs out. The fuel pump is running and I have fuel pressure on the line. I changed the fuel pressure regulator and it still won't run. What can be wrong?

How much fuel pressure do you have? That engine needs 60-66 psi to run.I hav eseen a ton of them make a little pressure but not enough to run the engine. Verify what pressure you have with a manual gauge

Use a test light and probe every fuse in the truck, both underhood and under the dash. Sounds like the injectors arent hitting.
