Good morning.

Does the truck have spark? The PCM needs to see spark signal before firing injectors.

If you do have spark, the PCM is bad as it controls the pulsing of the injectors.

If it does not have spark, then you need to check the crank sensor. Once you get a spark, the PCM should fire the injectors.
