the relay for both pumps is located underneath the passenger glovebox with the fusebox
the relay is in the abs pump

On a Rover 75 diesel, the fuel cut-off system typically involves a solenoid valve located on the fuel pump or near the engine. When activated, this valve stops fuel flow to the engine, effectively preventing it from running. The cut-off mechanism is often engaged in the event of an accident or when the ignition is turned off. Visually, you would see a small electronic component or valve connected to the fuel line, usually near the fuel filter or pump assembly.

There are a number of reasons for this, but varies between petrol and diesel. Diesels dont like the cold. The diesel engines in the 75 are BMW common rail engines.

I note the relay (part No NCL100040) is called an "ignition and glow plug heater relay". The 75 will usually start if you turn the key before the glow plugs have heated, therefore the glow plugs are probably only needed for cold starts. Glow plugs are not needed when a diesel engine is hot. The "ignition" reference may mean that some other circuit is controlled by this relay (obviously there is no conventional ignition as it is a diesel). FYI The part is also used on the Range Rover TD6 post 2002 An internet search suggest the cam sensor can cause starting problems and fault codes similar to a faulty glow plug relay.
To check the fuel pump on a Rover 75, start by ensuring there’s power to the fuel pump by testing the fuel pump fuse and relay. Next, access the fuel pump by removing the rear seat and the inspection cover. You can then use a multimeter to check for voltage at the pump connector while turning the ignition on; if there’s no voltage, further diagnose the electrical system. Finally, if the pump is powered but not functioning, you may need to remove the pump for further inspection or replacement.
The glow plug relay on a Rover 75 is typically located in the engine bay, near the battery. It is usually found in the fuse box or relay box, which is situated on the driver's side. You may need to refer to the vehicle's manual for the specific layout, as the exact location can vary depending on the engine type and model year.
