TU5JP4 NFU INJECTORS 1-4 NOT CONTROLLED BY ECU
Hi mates,

My TU5JP4 NFU (Peugeot 307, MY 2003, 1.6 16v) has start-up and slow motion problems.

I changed many part of the car (ignition coil, water and pressure sensor, spark plug, ...) but problems are still there.

I took out the injectors and start the engine. Only injector 2 and 3 work even when switching injectors (see the same problem here https://www.youtube.com/watch?v=8YkiutxJJjs).

What's wrong? Thank you in advance

Cylinder 1 and 4 share the same ignition coil, on the other hand one coil for the two cylinders. The problem should be on coil driver system faulty then the ECU shuts down the injection so the two.

Did you also check that there is no spark too ?

Thank you for your answer. I'll check for sparks as soon as possible.

Hi Zmann, thanks for the help. I checked for sparks, there are sparks at the 4 spark plugs.

Check for engine fault codes

I would check or replace camshaft and crankshaft sensors.If the problems keeps on,please look if you have good earth points for control unit.The last step,I think is ecu replacement.....

I Zmann, ECU is ME.4.4 and i have PP2000/DiagBox too. So i check for fault codes every times. 
The last diag detected misfire on cylinder 2 and 4.
