Thought this might be worth a new thread, mentioned on others previously but may help others.
2004 TD4 reports of loss of power on hills and misfire.
LP pump making noise like demented Swan, so suspected that.
Measured live pressures and revealed:
Across range 1000 to 3000 rpm.
Airflow 455 to 365
Manifold pressure 100 to 115
Lp pump 375 to 325 kPa
Hp pump 28600 to 59400 kPa
So all looks good.
Won't fail while I am driving it, but after a run uneven tick over is present and hp pressure is peaking upwards while ticking over, up to 33500 kPa. Just for a short burst.
I have cleared numerous fuel pressure codes which have not returned: P0191, P1195, P1260, P1470
Suggesting all is unwell, or has been unwell, with the fuel pressure.
Suspect fuel rail sensor or connector, but want it to fail before fixing it!!
Road testing today. Will report back. May be a pressure loom or connector issue.
Any other ideas please??
