SOURCE: no spark
First does the rotor turn when cranking engine?? possible timing chain is out or stripped gear..are you sure it has no spark??did you verify this with a high output spark tester ? did you spray starting fluid in the tbi unit ?

The troubleshooting charts for your ignition system are copyrighted and I cannot post them here. You can have access to them by subscribing to alldatadiy.com fo a small fee.
The MOST LIKELY cause of your problem is a failed distributor module. (inside the distributor) The symptoms you described can also be caused by many other things like loose or corroded connectors or even a failed Powertrain Control Module (PCM)

Check the voltage coming from the battery and check it again at the coil.I suspect you are not getting the proper voltage going through. Clean all the terminal ends to bare shiny metal and make sure all the connections are tight. If I remember correct your truck still has the HEI setup with the coil in the top of the distributor cap. If all the voltages are good, 12+ volts you should replace the coil. Hope this helps.
