Hyundai Matrix 2005 CRDI does not start

I have an Hyundai Matrix year 2005 Trichindric Credi starts and the issue is stopped. Fuel are changed when the circuit with the first activation of the pump the engine starts but then someone stops some idea that it can be or if it has the motor manual.
This engine brings a high pressure pump but it is not seen that a gear pump has incorporated to suck the oil of low or will it be that the electric pump feeds the fuel low circuit?.

From what I have seen, the electrical pump only works when we put the plate then when the engine starts, the fuel circuit is working with the lifting pump only if it stops it can be because air is being put before the high pump or the pump is sending under low caudal meter mear in case it has any damaged fuel sensor.

Hello, how are you friends to scan it many times in that car when it does not turn on it is because the position sensor of the Leba tree is flying ..
