Car has been sitting for about 5 or 6 days do to being rear ended.
The engine wants to turn over, but wont turn completely over, i tryd to deflood it but my battery gave up half way through. Im guessing i have to try and deflood her while being jumped? has this happened to anyone else. Its not a cause from the accident.

Not 100% sure, but some cars have a sensor that detects hard impacts and cuts power to the fuel pump as a safety measure. Since you were rear ended, check the fuel pump.
