Finally fixed after sourcing a new fuel regulator thanks for the help guys Lessons learned for me 1:- diagnose with lexia first 2: Should have removed the inlet manifold as this would have revealed the large amout of fuel and petrol which blackened the inlet manifold and port would have saved me a fair bit of money bit swapping and guessing Also discovered to my disgust the lack of support from Peugeot Citroen around making parts for this car anymore Regards Aron
