The battery somehow died and immo light blinking on the dash, engine doesn't even crank.
The ECU could not be accessed with diagnostic equipment. Eeprom has got very little data in it,
not quite sure if it is normal or not ...
Is it possible anyone to help with a sync or a dump if mine is no good.

Hi friend. The ECU could not be accessed with diagnostic equipment is possible becausse ECU without source power. Verify all fuses and ground wiring for the ECU.
