Hi have you had the fuel sender unit replaced this is located in the top of the tank, the most faults with fuel gauge not working is the fuel sender unit its usually the float attatched to it that leaks and then always read an empty tank, the fuel pump does not affect the gauge even without a fuel pump fitted the gauge will still work, now if you have replaced the sender unit then the chances are the problem is with the fuel gauge itself, have you tried banging on the dashboard where the fuel gauge is sometimes it sticks and giving the display a bang where the fuel gauge is frees it up so give it a bang and see if it moves, failing that the problem is going to be fuel sender or less likely faulty fuel gauge.
