Can hear starter but not cylinoid
If you can hear the starter then the solenoid is working as it has to work for the starter to make a noise.

Your fuel pump may be at the end of it's life and need to be replaced. Your going to have to check your fuel pressure at the shredder valve, to have the engine start you need 60 to 65psi. Any other readings will not start and under 55psi, engine will not run. It's common to hear the electric fuel pump working but the mechanical pump it self is worn out and can no longer provide the proper fuel pressure for your SEFI system. Good luck and keep me posted, be glad to help get you truck running again. Auto Zone has loner tool program and they will have the step by step instructions to get the job done.

If it is the factory Delco/GM radio, should work something like this.
Turn the truck on (does'nt have to be running just accesories on), turn the radio power off (turn volume knob all the way left till off, or power button off depending on the radio). I believe there are two buttons on the front next to each other, seek/scan maybe? Press and hold to change the time. One does hours, one does minutes.

Hi, if the extra wire goes to the alternator, then yes, it goes on the big post along with the battery wire. This is your charge wire. Please let me know if you have more questions, and thanks for using FixYa.
