start by replacing the fuel filter and cleanning the lines.

Then you need to check the linkage underneath the floor where it connects to the transfer case, and make sure it isn't loose or mal-adjusted.

i'll look through an auto repairs manual and post the cooling system diagram

There are a few things that can make that happen but usually all you need to do is make sure the emergency brake cable isn't frozen in the "on" position, then take the brakes apart, clean them up making sure nothing is rusted or binding and put them back together. Good time to replace the linings if they are worn but if not, it's not an issue. I've seen a few that even after being removed and carefully examined showed no real reason for not working but after doing what I said, they were fine.
One thing though....brake fluid is hygroscopic (absorbs moisture from the atmosphere) so it is a good idea to bleed them or at the very least, siphon out the master cylinder and re-fill it with fresh fluid to prevent future problems..

If you're sure the speaker(s) are OK, your problem may be a bad output stage of the car's radio.

I have found the wiring diagrams online to be unreliable -- they sometimes are listed under the wrong model or year, and have often caused me a lot of frustration and confusion. It is possible that you can get one, but for the sake of reliability you should probably pick up a Haynes manual for your truck - - it will have all of the diagrams you are looking for, as well as many other useful bits of information for repairing your truck. You might have more luck finding the diagram than I ever did ... but I still recommend picking up a Haynes manual for your future reference -- at under $30 US it can save you thousands in mechanic costs (if you have the time and tools to do your own repairs). These manuals are available at most auto-parts stores and larger bookstore chains.
If you are unable to find the Haynes manual for your truck, or just have your mind set on getting one online, you should include a bit more information to assist with your search:
1. Make, Model and year of your truck (which is here) 2. Engine size / type (is it a diesel, turbo-diesel, hemi, standard 5.7 L gasoline engine?) 3. Are there any engine or other upgrades that could affect the wiring? 4. Is it your entire wiring harness that needs replacing, or just the fuel gauge wiring? 5. Does the truck have an automatic or a manual transmission? (this can affect the wiring harness style and connections). 6. Do you know why the wiring burned out in the first place? (so you can possibly avoid the same issue in the future by changing where the wires sit when connected is possible)
I wish you the best of luck ... if you can't find the Haynes manual, please reply with the above information and I will do my best to help you find the appropriate wiring diagrams for your truck.

Sounds like a timing problem it could a worn out timing chain.
