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
