Try this but the fault I have is intermittent so may take a bit to work out - switch off everything in the car so there is no noise. Turn on ingnition (do not start) and listen for the sound of of the fuel pump below the rear seat - behind the drivers seat. The pump should run for about 5 - 10 sec then shut off, it may work but if you cannot hear it it may be an ECU issue. If it does run start the car and drive it until it stops again, switch the ignition on/off and listen for the pump running. if you can confirm that the pump is running intermittently you have the same ECU problem I have. The official solution is to replace the ECU - ££££££. The low cost alternate is to run a wire from the ingnition controlled feed at rear of the radio and connect to the pump feed at the fuel tank, ensure a correct rated fuse is installed somewhere along the wire. There is a least one issue with this - if the ignition is on the pump is running, so not a good idea to sit with the key turned to listen to the radio.

SOURCE: injectors

Injectors from the same ccm engine are most probably sounds same but to be on the safe side check not only the shape but code on the top of injector too. Because they are piezo effect injectors and set by the manufacture for a specific pressure for specific engine codes.

SOURCE: peugeot 406 hdi electronic immobiliser warning

did you try the spare key? are you sure it is an immobilizer light? what does the warning light look like, can you describe it? replacing the battery in the key will not help as it is not needed for the recognition of the key(this is done by an induced current).

Check the wiring to these components first, power and earth etc, if wiring is ok you may have faulty components, especially the primary lift pump in the fuel tank, these are famous for failing.
