Hi just got a TD4 runs great starts on the button when warm but is very difficult when cold.....
replaced rear fuel pump and filter still and one injector replaced still no go. Also when trying to start when cold the Rad cooling fans come
on!!!! Have managed to find Coolant Sensor and cleaned pins + WD40 ...... this seemed to help and it now starts a little
better..... I am going to replace the CTS ..... are these cars know for this??? ..... could it be the CTS when cold is telling the
ECU it is hot???? This may answer cooling fan start up can anybody shine any more light on this...grey unburnt fuel seems to
come out exhaust when it does fire ..... this clears then it is fine...pulls like a train. Help!!!
