The starter would have nothing to do with the speedometer not working . What year ,make , model vehicle ! Most vehicles the speedometer is control electronically . The VSS - vehicle speed sensor located on or inside the transmission ,is what the PCM - engine computer uses for speed information . The VSS is an input to the PCM , the PCM sends that information to the instrument cluster over a serial data communication network or data buss , then the instrument cluster controls a little electric motor to control the speedometer . So if the car runs good an shifts good the problem could be the instrument cluster .
