wont start

Car was running fine, I went to pull in a parking spot and it died. We tried jumping it but sparks started to fly. when you try to turn the key nothing happens. We tried to start it by overiding the started but it tries to fire but doesn't. Something is draining the battery. Tested the check engine light, and the coil packs and modulator, all came back fine. We are looking for what could be wrong. Any ideas let us know Please.

The coil pack usually wont set off a trouble code. Does the car crank but not start or does it do absolutely nothing? If you got sparks from trying to jump start it, you either had the cables crossed or you have a hot wire grounding out by the sounds.
