Diesel not starting after cam belt change

Hi guys hope you can assist me.
I'm from RSA.
I replaced die fuel pump on my 2005 c3 1.4hdi.
Cam belt is replaced and all marks line up.
Bled out air from the injectors.
The problem is its not starting... At first it seem as if it Wil go for 1sec and then it's just not.
I noticed on the clear fuel line (return) that the fuel seems to flow back when it stands for a while.
I'm seeking some advice on this matter

Hi

Did the engine run before the work

And, why did the fuel pump get changed?

Yes the car was running until some noise came out from the cambelt side. I opened up and the fuel pump was wonky... Maybe a bearing or something.
I got the new fuel pump for a good price and decided to replace the fuel pump instead of repairing the old one...
So yes the car was running.
The new fuel pump does pump as I Bled out the air

SOME feed back its been some months now and stil no luck... A dieselmac told me that the engine is not getting fuel... I Bled out the top fuel rail and now air commung from the return. Can it be on the injector side that there is stil a airlock? And if so, how do I get the airlock out of the injectors and injector pump?

Have you cracked the injector nuts at the pipe union? It is a dangerous thing to do because of the high pressure fuel, but it can tell you if the fuel is at least getting to the injectors.

Good day.
It's very difficult to get to njectors nuts... So I haven't done that yet. I know on older diesel engines that's the best and easiest way to bleed out air of the fuel system, but now where have find a tutorial on how to bleed the high pressure side of this hdi engine. Only got ways to do the low presure side. So I have thought it's only necessary for the low pressure side... Maybe some advise on this would help as well.
I have ordered a cheap diagnostics unit to help me get fhualt codes and clear them and see what pops up again to fix it that way.
