2011 5.0 Range Rover (NA) The low pressure fuel system is reading 79.6lbs and a fuel pump duty ratio of 33.25%, which I understand is in its correct range. The high pressure fuel system according to what I have read should be around 1500psi at idle and around 2100psi above idle. I'm getting readings of 225 to 300 psi at idle and between 500 and 800psi above idle at around 2000 to 3000rpm. Find it strange that the engine starts immediately and runs well except its in the restricted performance mode and the computer has only one error code of P0087 indicating low fuel rail pressure. So I changed the high pressure fuel rail sensor mounted at the far end of the right side fuel rail and it did not change the low readings and still have the P0087 code.
It appears my only next step is to replace the two high pressure pumps on the right side of the block.
Just wondering if I missed anything that could cause this problem..?
Thx.
