The truck won't start and most lights on dash don't come on unless jumping from another vehicle. I've replaced relays, ignition switch and ignition cylinder...

What is your question?

The truck makes no clicking noise. I've tapped starter, with no avail. This happened a week after installing new battery. Seems electrical to me, but I have no idea where to start looking.

How long has your 2004 GMC Sierra 1500 had this problem?
