Hi all , I’ve a fiesta st 2014 eco boost won’t start , with a fault code po53f cold start fuel pressure ,
tank pumps working and supplying , ( not check pressure yet ) , I’ve replaced high pressure pump , cam bucket , fuel rail with injectors and regulator , no leaks , cam lifts good ,
good spark , engine speed signal ok ,
before I drop the tank is there any thing common on these engines that can throw up this code ,
plugs don’t look wet after turning over for a good period ,

many thanks in advance
