Thread: Fiesta 1.4 TDCI poor starting and low power

    Default Fiesta 1.4 TDCI poor starting and low power

    Hi, we have a 2002 Fiesta 1.4 tdci diesel with 88k on the clock. It has become difficult to start on cold mornings and cuts out if we lifts off before it warms up. It is very sluggish in acceleration and will not drive at more than 70 mph. It has been checked on several different diagnostic systems yet does not return any fault codes (only checked when warm engine). When trying to start from cold it emits a cloud of grey/ white smoke while turning over and makes a lumpy, banging noise before eventually catching on and firing up. More difficult to start when very cold or fuel tank is below quarter full. Once it is warmed up it starts much easier, but the power output is very sluggish. No acceleration for overtaking and crawls up hills with foot flat on the floor. Air bubbles are visible in the fuel line. Patchy service history so don't know when fuel or air filters etc. last changed. Dual mass flywheel and clutch and cambelt recently replaced. All the suggestions so far are very expensive and don't guarantee to fix the problem. Any ideas please? Thanks. Pete, Southampton.

    Hi Pete,

    you wil need to have a "live data" readings and a leak off controlled measurement session, a bit more advanced these days,

    A Good local Inependent Garage, should have the equipment available to diagnose this issue.

    From your description of bubbles visible in the fuel pipe it sounds like you are getting air into the fuel system.

    The hard starting could be related to this or it maybe a problem with the glowplugs or glowplug control circuit.

    Unfortunately, Anything to do with repairing cars is expensive.

    Hi Wes
    thanks for the reply but don't know what that is. How does a "live data" session differ from normal diagnostic tests? What does a "leak off session" mean please? Thanks. Pete

    Hi Mr Danno, thanks for the reply.

    Would air getting into the system also cause the lack of power do you think? I would have expected a problem with the glow plugs etc to show up on the diagnostic check, or would that be too easy?

    The reason I say it is expensive is because the local Ford main agent has quoted us 1300 to replace the injectors, but won't guarantee that this will fix the problem. Having spent similar money already on the flywheel and clutch replacement we are not keen to spend this kind of money again without a bit more certainty of success.

    To be honest, It is impossible to say what is wrong without doing some simple diagnostic tests.

    The 'leak-off' test is done by attaching little bottles to the leak off connection on each injector. The engine is then run and the amount of diesel in each bottle is compared.

    If there is air leaking into the fuel system it will cause problems as it will stop or reduce the amount of fuel getting to the injectors.

    The glowplugs can be tested in the car by measuring the resistance of them and checking there is power getting to them.

    I would be inclined to take it to a diesel engine specialist rather than Ford.
