Ford Fiesta 1.6 TDCi 2006 - Very Bad Problem

[SX50_Tuner]

Hi,

I just bought my first car (name in title) and my dad was driving it home today going about 50mph and then all of a sudden, we heard a knocking and then the engine just cut out, no scraping sounds or anything like that. My Dad's a mechanic and he said it could be the fuel pump or injectors/injector seals. I just want to know if anyone else has ever had this issue and what needed fixing. Absolutely gutted so would really appreciate the help.

Thanks

It could be one of a thousand different things.
Impossible to say for certain without examining it.

As your Dad is a mechanic, why aren't you getting him to diagnose /repair it?

Because I just wanted to see if anyone knew what it was before he had a look. Just to save him some time.

When trying to start it, it still has compression but it's chucking white smoke out.
