First, does it have any codes?
The injectors may be the issue but need to be tested before any repairs are even attempted.
The fuel pressure needs to be verified as well.
You need a good truck shop with the proper tools to do these tests. Then you can find the exact failure and can proceed with your repairs.
Guessing on these motors is very expensive and mostly always wrong.
