Help! Citroen C3 non starter

[easytech]

Hi to all.
I have a C3 1,4Hdi in the shop it fires up and then immediate stops. Looks like immo problem but thats not the issue.
The engine is swapped because the old one had bad pistons.
I know that the new engine is a later type then the old one.
All sensors and wiring are swapped but not the injectors.
I have Lexia and there are no faults at all.
Railpressure 250bar while starting crank/cam in sync. Ecu unlocked and synchronised.
Anybody have some light on this?

check CKP sensor and adjust its position carefully. sometimes if the sensor it's not fitted right, it is capable of reading the engine rotations when crancking, but after the engine start it will suddenly stop.

Thanks for the answer.
Checked that but it is not ajustable.
Tomorrow I get the old parts from the wrecked engine, the part numbers from an old and newer version cam and crank pully are different so maybe there is a timing issue.
