This can be a fault internally in the ECU itself and it is also possible the programming was damaged or wiped out by the ecu.I would have the fault codes read out of the ecu with a compatible scan tool or computer plugged into your model to see what codes are set.Any codes set then need to be diagnosed to then locate and repair this issue here.If no codes are set then I would see if a shop or dealer can try to reprogram the ECU to see if this resolves the fault and if it does not then the ECU may need to be replaced.

That shouldn't be an issue with the injectors themselves at fault if they were not an issue before the battery went flat.But if the engine ECU has lost its programming or programming is corrupted when the battery went flat it can cause this issue as well as injector codes.In some cases, all that is needed is to have the engine computer re programmed by a dealer to resolve this fault.But in other cases, it may need to be replaced.
