It can be hundred reasons, so you need read errors. However first check is it correct fuel pressure on rail. When you crank engine, it must be 350 bar +/- 50 bar.

tdci 135ps,

Sorry to hear that I would be checking everything is plugged in and no broken wires, check the crank sensor, cam sensor, cht sensor etc, if it was running ok in the donor vehicle and not now it could just be a case of a loose/no connected plug. N

Could it not just be air in the fuel system as that's all that's been disconnected and reconnected
