if the cable and cluster are good, the next thing to check is the plastic gear on the end of the speed sensor that goes into the side of the transmission. Unbolt the retainer and it just pulls strait out.
your speedometer is mechanical and your fuel level is electrical; these are probably two independent problems.
If the coolant temp gauge and oil pressure gauges are working, I would assume that the 5 volt regulator is OK. Float could be full of gas. Bad sending unit. Bad connection on the tank plug, or bad ground.
