Hyundai Matrix

Dear friends, I have a Hyundai Matrix 1.5 CDI that when I leave it all night off, the next morning does not start, once I manage to start it I can use it all day is summer or winter.
I have already changed the battery, the starter engine, the heater and the diesel filter, they have reviewed and almost changed the whole car (with the pasta it supposes), if any of you has had this problem, please help me because they no longer know what the mechanics do.
As help I can tell you that giving it a push of 0.50 cm the car starts without problems.

I await your answers, greetings and thanks.

Hi MAJO because of the push so small, it may be, if you have your car, the camshaft sensor or some other type of sensor that detects the position of the engine before starting, it has happened to me with a Santana only that it could not start. I hope to help

The symptoms that you comment have seen them in a Corsa of gasoline, when it seemed not to start but with a small pushing istantaneo. It was the revolution collector did not give any error and once in motion perfect

To a colleague my spent in an Xsara and at the end of everything it turned

But is it only in the morning games? Ami happened to me something similar with an H-1 and alfinal was not the filter or the pump was only the basis of the filter that brings a small metal lain that serves as an antiretorno of the diesel, then at the night where the vehicle was stopped the fuel line was emptied and the fuel line was emptied and the next day it had to fill again.
Trying the diesel filter in the morning before starting the engine.
