I am sorry that you have not been helped yet. I just came online and saw your question.
You can try a hard reset of the control modules, which may clear the fault long enough to allow you to start it.
To do this, disconnect both battery
cables and either tape or clamp their ends together for 10 minutes. This discharges the capicators and resets the modules to factory parameters. After 10 minutes unclamp/untape and reconnect to the battery and try to start it
