Vehicle towed in with non running situation,fault code read two faults found 1112 fuel pressure intermttant low pressure and 1118 electric fan no1 poor earthing and or battery.The vehicle will start every time if fault codes removed or left for a short period of time but will stop when put under load,however will tick over almost forever.When observing live data all fuel pressure is lost momentarily just before it stops as though switched off. The vehicle had a history of this fault over a year ago with the dealers spending months rectifying the fault(they will not give out the information what was carried out other than to say they replaced fuel filter and housing under warranty surely this job would not have taken months to do , more likely they had a wiring defect )though i am led to believe the garage before the dealers had replaced the intank fuel lift pump but could not find the cause and effect of this non running and washed their hands of the job.It seams as though this model has a wiring history of this problem among others with this common rail pressure system.Has anyone come accross this or may shine a light to it. I HAVE SCANNED ALL THE WIRING AND REMOVED AND CLEANED ALL THE VISABLE EARTH POINTS. your help would be appreciated
