If 5-8 volts exists, go to next step. If 5-8 volts does not exist, check for poor connections or open in Blue/Green wire or Black wire between fuel gauge and fuel gauge sending unit. Check for poor connections or open in Black wire between fuel gauge sending unit and ground connection. See WIRING DIAGRAMS . Repair as necessary.
