The car has sat for quite some time but started monthly and I decided to clean off the winter dust but the battery was dead. I hooked it up to jump it and all does is click but won't crank. The one time it cranked, I heard a electrical pop and everything went dead. Then the connections to jump start the car under the hood no longer worked so I checked the fuses, all was good. I then hooked up the cables to the actual battery which got electricity going again. Sitting with the key turned to ON, the engine light flashed 10-11 times after about 10 seconds of being solid. So then I turned the key 3 times to check any codes and it says "done". Lastly, I unhooked the battery to clear any bugs and see if that would help, still the same thing. After I pulled off the jumper cables, the battery died almost immediately so it held no juice so I'm thinking the battery is simply toast. Anyone's thoughts?
