there is a nipple on the fuel rail where the injectors are located...open the dust protection cap on the fuel rail and press on the valve and check if the fuel is coming out with pressure then ur fuel pump is working. if not then it's not working. also by listening to it you can identify. switch the ign. key to position 2 (on) and keep listening. if you hear a noise like bee then it's working. if it's so silent then do the first procedure and check if the fuel coming out pressurized. if not then it's confirmed not working

if you mean by d ECU is the Engine control Module then you must have it learned with the BCM (body control Module). This could be done using T4 or something equivalent

I would recommend that you bleed all air out of the cooling system. The bleeder valve is located on top of the engine. Once engine starts to overheat or when you can hear bubbling back into the overflow bottle, turn car off and open bleeder valve. If you see bubbling you have air in your system. Bleed the system a couple of times and see if this helps.A heat sensor sending unit which controls activation of the electric fan could also have failed.But is the heat sensor is properly working then check the radiator cap is it properly fitted or got loose.If its loose it will release the pressure and car will overheat.But if the radiator cap is properly closed.Then its time to check the HEAD GASKET.As you have mostly replaced all the possible faults for overheating and if other mentioned possibilities are checked OK.Then its time to check and replace head gasket. Thanks. you can rate this solution and show your appreciation.

YES. But you only want to do it 1/8 of a turn at a time. once you go to tight there is no turning back. But I would check front end parts first for play.

Sorry but Land Rover is one of those car companies that make their car so it can only be worked on by one of their mechanic's.
Except for changing the battery inside the remote you are going to send it to them.

You must go to the land rover dealer to connect the tester T4, it will then tell the technician whats wrong and theywill advise you of repairs and costs. There is no alternative. Hope that helps
