Hi 2004 Mondeo TDCI may be injector trouble wont start. Has anyone connected an injector to the common rail but externally on a healthy car. I have tried this today one at a time with each injector, electric connected and engine running (on 3 cyls) each of my injectors from the non running car dont inject any fuel! Surely all 4 unlikely to be faulty, not sure of history on the car 100,000 miles any advice appreciated!
