Thanks everyone for your help to date.
The fuel filter has been changed and there appeared to be no problem with the lift pump when I bleed the air from the filter housing.
I will post the codes as soon as I can have them read.
Also the vehicle had a new Blue label IP fitted about 8 months ago before I puchased it, and they have remotely mounted the FSD to a piece of 3 mm steel plate near the AC compressor.
This vehicle was running fine prior to this problem occurring overnight and was returning 7.5 Kms per Litre on the highway.
Look forward to hearing from you guys again.
