I have a 90 gt, car was back firing at high rpm’s like it was out of time. While driving my bypass hose busted and after parking it and replacing it car went completely dead. So I jump it and drove around for a few. Again dead, battery is fully charged, Solenoid, battery, ignition, ignition switch, alternator all good. Replaced starter and back fire went away. Still just clicks and will not start on jump start charger just from another vehicle. And suggestions?
