Your post is very hard to understand,
but the fuel pump is completly mechanical, there is no computer that controls the fuel bowl filling up. Turning the key on or blown fuses does not matter.
The bowl fills up by the engine turning over, a lobe on the camshaft runs the pump. The only way the bowl will fill up is if the engine is turning over. Turning the key to the on position does nothing to fill the bowl up.
If the truck runs when you manually fill the fuel bowl up till it runs dry, it doesn't sound like there is anything wrong with the engine. It sounds simply like you are not getting fuel from the tanks.
Could be the hoses were reattached incorrectly on the fuel pump/bowl, tank selector switch issue, restriction in the lines, empty fuel tank,
