Was the truck actually running before you replaced all these parts?
As budwich said, go back to basics. When you turn the key to Run, do you hear the fuel pump prime up for about 2 seconds? You might need to have someone back by the fuel tank to hear it. If you don't hear that, the the most likely suspects are the fuel pump itself or the fuel pump relay. Could also be the ignition switch or the wiring to the fuel pump. If the truck was running before you replaced all these parts, then start looking at what you changed out. It's always possible to have parts be bad off the shelf. If it was *not* running, then you may have missed the actual cause.
If the fuel pump is running, make sure you have proper fuel pressure. If you do, then check for spark.
If the squirt of starter fluid budwich suggests above gets your truck going for a few seconds, then you have spark. Those two things should get your truck running, unless the fuel is not being delivered to the injectors. A failure at that level should be throwing a code.
Let's start there and see if we can narrow down the problem.
Good Luck!
