Hey guys I would like to know if anyone would know why my truck won't do anything? When I turn the key to the on position the fuel pumps don't purge and when I turn it all the way as if to start the truck the relays in the drives compartment just click. And some how the window fuse under the hood has blown.

 

Sounds like a dead battery, defective battery cables, or cable connections.

The fuse blew because too much current tried to pass through it. That usually means a short circuit to ground.

Fix the supply system first.
