Does the injector need to be coded?.

I know it is not easy but I would suggest doing a. Compression Test May have broken valve springs.

A lot depend on what equipment you have a pro level scantool on most German diesels live data will give you an intake air grams/stroke reading for each cylinder that can help spot a valve or blocked intake port issue.

The main suspect though is going to be a compression issue, diesels need at least 300ps/22bar for a cylinder to fire without a misfire.

Basic checks on power to the injector but beyond that you would need a scope.

It is of course possible you have a bad replacrment injector. Only way to tell would be swap it to another cylinder
