Renault scenic 1.6dci fuel pressure problem

[koranx]

Hello, I have a problem with a Renault Scenic with a 1.6 dci 130 engine.

The problem is that the car starts at idle, generates 1800 bar of fuel pressure, runs for a while and then turns off.


If I press the accelerator pedal all the way, the fuel pressure drops to about 150-200 bar


So far I have done the following in the car:


1. High pressure fuel pump


2. Low pressure fuel pump


3. Injection rail with a mechanical valve and pressure sensor


4. Fuel injectors


5. Fuel filter


6. Fuel in the tank replaced


7. Fuel system patency


8 . checked electrical installation


9. Replaced engine controller


I have no ideas what could be wrong with this car

it is possible that you have the wrong fuel pressure control valve, it works the other way around,

tienes un corto en algun sensor

Check the power for the sensor. Peugeut uses the same power for some sensors and actuators, so if the actuator is faulty the power drops for some sensors too and then the measured values drops too.
