Diesel Leak Around Injectors...... Read And You'll Understand It Better Lol

[Bailey2.0]

OK so basically I had a 2.0 TDCi Zetec S a few years back on an 04 plate that had diesel pooling around the injectors. It turned out to be the Leak off pipes/ connectors, we changed the lot to be sure. However when we changed it the car would not start at all! It took about a week of disconnecting and really connecting rando stuff to.get it finally started in limp mode. After that it was fine and the error we were getting of low pressure in the fuel rail went. Now I've just bought a mondeo 2.0 TDCi Zetec again with the same issue if diesel pooling around the injectors. My concern is ill.change the pipes and connectors and my car won't start again! Can anyone she'd some light on why that would happen?

Thanks in advance :)
