A code scammer as posted above spitting out a number does not allow live readings in real time while your driving what the fuel rail pressures are which a different scan unit offers.
Analog or digital gauges with a laptop will show you what is out of spec. A pressure gauge connected to the fuel rail, take the rail return line back to the fuel tank and pinch off a couple seconds allowing a quick check the maximum pressure the fuel pump will generate to eliminate the fuel pump as that problem. One less PITA labor to replace item. Also rail pressures knowing what they are will establish what the pressure regulator is maintaining be it too high or too low as they can and will fail. Sensor failures the last on the list of suspects also an item that might or can fail. It's a Land Rover.
Note all the above tests costing not a single penny vs throwing expensive parts at it until "fixed". Expensive dealership repairs, labor the clock's ticking including replacement of unneeded parts as "customer pays". They then become the miracle mechanics to the average LR owners, so sad.

There is no way to check the high pressure fuel rail pressure... there is no valve to test from and it is in the thousands of PSI's.
