Truck is not getting fuel.Would start sometimes and not others. Replaced fuel pump and it was still doing the same thing. Now it doesn't start at all. Spray starting fluid and it will start.
Get a fuel pressure gauge and see what your're getting for pressure. You may have a bad fuel pressure regulator. If that tests fine, I would then move to your injectors.
