Fuel low pressure warning on Seat Ibiza

Asked by Adnaan Sep 23, 2019 at 09:03 PM

Question type: Maintenance & Repair

I am an 18 year old student studying autotmive engineering at uni and have a
problem with my car I would like to know more about. I have a 2011 Seat Ibiza
1.2 TDI that has done just over 100k miles. It has a check engine light and the
glow plug light flashes occasionally. The engine light is permeant and the glow
plug light sometimes flashes when the car is giving syptoms but then
sometimes the car is fine and the glowplug light does not flash. When it does
flash codes on a snap on ECU come up saying that the cars fuel rail system
pressure is too low. I bought a new fuel rail which I installed and the car could
not start. I assumed it was a problem with the fuel rail so I bought another and
installed it. The car started eventually but took some time getting started with
the ignition on. At first there was no warning lights but eventually they came
back on, same warning of fuel rail pressure being too low. Is this to do with
something else possibly the pressure sensor on the fuel rail itself or could it be
a more serious problem such as the fuel pump or an injector. The car
occasionally idles higher or very rough and out of balance. Aswell as this it
sometimes struggles to pick up speed or the miles on the dash suddenly go
from 100 to 75 even though I have done 1-2 miles. Any help would be
appreciated as I am very interested in diagnosing the problem but do not have
the money to try all the options. Thank you.
