Our peugeot 807 2.2 hdi 2004 manual gearbox with 85,000mile will not start, Turning over fin but says econony mode active. Diesel is getting in to fuel filter fine but engine not firing. As I say it turns over and not starting. Windows and central locking also not working I guess this is due to economy mode.

Also can anyone help me locate the fuel relay (picture would be helpful)
Thanks in advance
