Hi Tony,
Which fuse is it that has no power? It sounds like you are referring to the fuel pump, but if the truck starts and runs, that can't be correct.
I reviewed the codes, and they all deal with the fuel gauge. To set the P461 and P463, the sensor voltage has to be above 3.5v for at least 30 seconds. When this happens, the fuel gauge defaults to empty.
A defective level sensor will likely not set the P0463. Chances are the problem is in the wiring or connectors at the sensor or the ECM.
The 461 is set when there is little to no variation over a specified amount of time while the engine is running. This is likely the result of p0463.
The 230 indicates the control module detects that the commanded state of the driver and the actual state of the control circuit do not match. Again, I think this is resulting from the 463.
If you look at the pics below, I have provided the description and diagnostics for the code. The last pic is the wiring schematic for the gauges.
Let me know if this is something you feel comfortable doing. Also, here is a link you may find helpful when checking:

Let me know which fuse has no power, the engine size, and if it is 4wd.
Take care,
Joe
