My 2001 F150 registers the gasoline level immediately. I believe all dash indicator lights come on at some point as the truck starts to demonstrate all is working.
Ok but this is odd. Some years back I filled the truck in Las Vegas with the engine running because it was very hot. The fill up did not fully register for 50 or 100 miles. These gauges are controlled by the computer and I believe the computer must reset when the vehicle is turned off as it relates to the fuel gauge. This day it took about an hour to register and made me question if I really had it full as I headed north on highway 93 where gas was scarce 17 years ago.
Definitely check the start battery voltage before and after you start the vehicle to verify alternator function.
You could try filling the tank (engine off) and see if the level indicator improves. Otherwise I think you are looking at a new fuel level sending unit. I don't know the diagnostic on this item. If you take it into the shop they will appreciate if it is low on fuel.
