Question about 2004 Chevrolet Silverado 2500HD
The problem you are describing is common in the type of starter design this truck uses (and all GM cars and trucks), the starter solenoid has heavy copper contacts inside it that energize the starter when the plunger in the starter solenoid is pulled back by the magnetic field, that is the clicking or clunking you hear. To repair this you can either pull the starter out and replace the copper contact feet inside the solenoid on the starter or you can just install a rebuilt starter, which I suggest on cars and trucks with over 75,000 miles on the ticker. The starter is located at the bottom rear of the engine at the transmission bell housing, it is held in by two bolts to the engine block, disconnect the battery before starting any work and mark the wires remove from the starter solenoid, not marking them is the single biggest error you can make, there are only 3 or 4 wires but you can still get them mixed up. Rebuilt starter are very reasonably priced for most V8 engine used in the HD, the one exception is the Diesel. If you have time to wait for a part you can save about 40% over local parts stores by ordering from an Internet parts supplier called www.rockauto.com You can also buy a rebuilt kit here fo rthe solenoid. http://www.nationsautoelectric.com/Nippondenso.html
Below is a picture of the contacts that burn. There of course are two contacts.

I had the exact same thin happen on my 2004 Chevy 2500hd with the 6.0 gas. I'd turn the key and everything would light up and turn on but when i turned the key..nothing. it's click once then nothing.I'd wait try again and may be a few more times then i's start right up Happened multiple times. I realized that my positive terminal was a little loose on my battery. Just a little bit. I cleaned it off and tightened the ever living crud outta it. Never had a problem after that.

This problem can be related to few things.
1) First check the battery voltage.It should be 12 volt.If the battery voltage is less then 12 volt, then recharge the battery and then check.
2)Other possibility is short in ignition switch circuit.The ignition switch wiring harness receives power from battery, if this connection is getting short in between or getting loose, then ignition switch will not function properly.--------
3) The connection of battery to alternator and connection of battery to starter.Check both.
4) Get all the 3 things battery, alternator and starter checked.If there is no or low voltage, then that is the cause of problem.
5) Re check the starter, if the starter solenoid is getting jammed .
In most of such cases, its ignition switch getting short starter solenoid getting jammed.If its starter solenoid problem or starter motor problem.The starter needs to be replaced.
6) If all checked ok, then check the fuel pump relay.The relay located in the engine compartment fuse box, under hood.If this relay is shorted, then it will not let the fuel o reach engine, and due to lack of fuel or no fuel the engine will have power, but it will not start.Also get fuel pressure tested at local car garage.If fuel pressure tested low, then its faulty fuel pump and clogged fuel filter.It has to be replace.-----------------
This troubleshooting will help you to locate the problem.As per that, you can get the faulty part replaced.This should help.Thanks.Helpmech.
