My Land Rover Range Sport 2007 year
2.7td V6 140kw
it throws me error P0087
but in normal driving it goes over 600km without a single error, when I load it I make the gas to the floor it immediately reports error P0087,
I put a new pump in the tank, a new high pressure fuel pump, a new Rail sensor, still the same error

Chased this fault for over a year turned out to be faulty new hpfp from euro car parts replacment pump finally sorted it.
Where did the pump come from they fitted ??

Hi “ Lrstaylor “

Well after the dealer replaced the already new high pressure pump which I got from a Land Rover specialist, they had put in there own new guanine Land Rover pump and the car only lasted a 30 miles test drive before going back in limp mode they where about to changed the pump again for a third one but decided it can’t be the pump as the two new pumps where both showing the same low reading and couldn’t both be fault , or so I hope

Yeah that's what we thought the car came to us with a new pump fitted some months later we replaced the pump for a euro car parts new pump still had p0087 but only in colder months come the summer it ran faultless.
After a year of messing about swopped out the pump again problem cured. The pump we removed was leaking from the rear shaft.

Many places are fitting recon pump instead of new good luck

Well unfortunately we have been chasing this fault for 3 years now
All started after the original high pressure pump failed so we changed it are selfs car then started again but ever since has had this fault , it was at a local garage for 2 months they couldn’t fix it then it went to a Land Rover specialist they had it for 7 months! They also couldn’t fix it after changing lot of parts including the intank pump , then eventually took it to are local Land Rover dealer which changed the high pressure pump again then the intank pump again and lots of other stuff,
But now they are going to try run new wires to the high pressures fuel pump from the ecu to bypass the original wiring “ even tho the wiring is testing fine they have seen before that if two damaged wires touch together they correct a good reading but lose the communication “ or so the master technician told me a few months ago ?

I have also told them to investigate the fact that when you turn the ignition on and look at the fuel rail pressure on live data with my gap tool the rail pressure is 1000kpa compared to are other car a D3 it’s only 350kpa with ignition on and runs fault less , the master technician said of the top of his head that 1000 kpa was too high he thinks ?

Which is strange if it is to think that even tho the sensor is also new and had its wiring tested it’s still reading too high on ignition but always reading too low when the cars running.
When first stated it’s 28,000 kpa perfect reading but after a few minutes drops to only 23,000 kpa at idle !
very very strange car !
