I have a 1980 Datsun 510 has 80,000 miles on it. The problem im having its been hesitating to crank over it clicks then i turn the key back to off then the next time i try to start it will start. But it seems to be getting worse. Im thinking its the starter the battery is fairly new and the charging system seems to be working. Also my temp gauge was working and now does not work does any one know how i can check the problem. Thank you .
