Dear Members
Need your kind assistance to start my Discovery 3 Diesel
Its showing following codes
P0405-00 Exhaust gas recirculation sensor A -circuit low
P140A-00 Exhaust gas recirculation sensor C -circuit low
P138E-00 Turbo charger boost control position sensor A- minimum/maximum stop performance
P0087-00 Fuel rail / system pressure- too low
P0118-00 Engine coolant temperature sensor 1 - circuit high
B1B02-28 Low frequency coil
B1C57-14 Unused relay drive

sorry for this long list, I have cleared all codes but above codes are still showing
I am new to Landrover discovery and really need your help to start it
I have charged the battery fully
engine cranking but not starting

PLEASE HELP

Lack of fuel pressure is your problem, has the pump belt broke, when was fuel filter last changed, or the low pressure pump faulty
