Fuel pump running constantly

[LukeZS96]

Bit of an issue with the 1.8T ZS. The fuel pump is running constantly even with the key out. Have checked all relays and wires and all seems okay. No issues with fuel pressure or any leaks anywhere so I am thinking it could be down to the ECU and remap it had. Has anyone else ever come across something like this with remapped ZSs or could it be BCU related? Its wrecking my head at this stage

Thanks folks

Was it like this straight after the remap? If so then maybe it needs checking. Unusual to hear all the same.
