Rover 75 cdti

[Adept]

Hi All
I have a rover 75 cdti which was running great parked it up one night, an next day would not start (not turning over) battery is fine mobilizer working fine ecu working glow plug relay working fine tested for volts at ignition switch to solenoid volts ok at switch, earth seems ok from engine to battery, I can hear the fuel pumps running but nothing when key turned to start, not even relay click or solenoid click, not yet tested that as not sure how to get at it perhaps someone could tell me where the starter solenoid is located.

Thanks.
