hello G world! im new to this G thing and i just purchased an 05 g35coupe ( used of course) manual and it wont start. Every time I endeavor to start the car it makes a clicking sound(Obviously Im not car literate yet,) Ive jumped start the car and let it run for a few minutes, then attempt to restart it again , same problem. The radio, windows etc works. Does this mean it can still possibly be the battery?
