Missing Power in Boxer 2.2 HDI

Good to all, I have a problem with a Peugeot Boxer 2.2 HDI of 2005.
Soon to start the engine, a red light (engine) is turned on and the van does not exceed 2500 rpm. The stops and if you try to start, but if you take away the key and put it again it starts and as if nothing. The injectors are fine and the connections are also reviewed.
By the way, the diagnosis machine the only fault is lack of fuel pressure.
Thank you all

If the diagnosis tells you that, and your peugeot is 2005, it is caused that the electrical pump is in malfunction, this peugeot has an electrical pump that sends the fuel to the Camon Rail mechanical pump, if it is well generates a good flow and a good pressure, the problem lies in a valve that is inside the mechanical pump, this is a lift valve that is to supply the precion of the system. The 2500 rpm, I tell you because a 2005 boxer arrived with the workshop with the same problem and after the Peugeot house changed an infidity of things the owner no longer had money or wanted Precion is fine, if you have a better manometro, this electrical pump is used to get the oil to the mechanical pump, nothing more than that, and the lift valve is the one that worries the precion and the flow for the highest RPMs, any questions question, the pump does not disassemble the pump.

Thank you, it is already solved, check the pressure of the pump with a manometro, it has to be 2.5 bars.
Combe the leftover of the injectors and there was one that had a lot of excess, communicated through its interior. That was the problem.

Ok thanks for communicating the problem then it was the flow of return, now that you tell me that, that was also one of the problems that I repaired did not remember thanks for refreshing the memory and for publishing your answer.
