When the filter sensor is connected (Which i'm guessing measures the raise pressure) the engine does not rev above 2.5k. Does this suggest the sensor or the raise pump is faulty?
Can I also add how good this site is. I will become a doner once I fix my car (skint after buying car and paying iinsurance, and looks like more bills to fix car!) This is one of the best websites i've ever come accross. Well done.
1.4 raise pressure is terrible while running.should be 4 bar minimum.You are quoting while running arnt you???i wary of saying you need a new pre supply pump but that is far too low for car to run.Can you check live data with ingnition on and watch what it does without starting it.Should go to 4 bar than back to 1 bar after approx 20 secs and say there.Then start it and see what it rises to.should go to 4 bar immediately and post back.
Based on what you have said though a running pres supply of 1.4 is totally unacceptable far far too low but this can be caused by leaking injectors bringing it down to you have to be aware.(leaking into engine possibly). www.eurocarparts.com sell the pumps for about £150.
