Renault Clio 3 1.5 dci year 2006

Good partner,
I tell you my problem summarized. RENAULT CLIO 3 YEAR 2006 Motor 1.5 DCI 132000KM. The car doesn't want to start. When he manages to start it only 1-2 seconds and drown, suddenly stops. In other words start (when you want) but in 1 second one stops. Any advice?
I have changed heater high pressure pump but still does not want to start. Any idea?
Thank you

Your problem is in the injectors the fault is that they are returning a lot of fuel that is why it starts or when it starts it does not keep the march to disconnect the hoses that go in the injectors by there returns the diesel there you give it starts and you look at you that quantity returns practically it should not return anything since it does not injected any fuel to the engine. If you have a lot of return with the injectors replace them all is the solution in those vehicles, do not change the injectors' platelets because they do not last anything greetings
