I have a 97 Del Sol with an issue that it often times dies on me and i need to jump it every time i want to start it. It will go into accessory mode but when i turn it over it just clicks and everything shuts off. my battery, starter, and alternator are all good (I've tested them) My theory is i have a bad ground or a wire that's been rubbed raw or something, any ideas? Id greatly Appreciate it!

 

post a pic of the battery terminals, a lot of times the inner part of the terminal is corroded and causes a poor connection. the car is starting with a jump because your now connecting the power to the outside of the terminal
