Because you probably damaged the sending unit or the wiring attached to it, or else it was loose or broken to start with.
as soon as you start the vehicle it should register
fuel gauge not working
are you sure you reconnected the wire to the gauge when you did the fuel pump? also the gauge requires a good ground to the tank. its possible you don't have a good connection. just some thoughts.
A common problem with Honda cars is that the fuel gauge is stuck on full. This problem is solved by replacing the gauge cluster.
either the fuel gauge needs replacing or the fuel gauge sending unit in the fuel tank is stuck
In most cases the fuel gauge sending unit inside the fuel tank is at fault.
The cause of the faulty fuel gauge is probably the fuel gauge sending unit located inside the fuel tank. Replacing the sending unit would require dropping the fuel tank.
No, not if the pump is working.
possible bad ground
No it is not working.
