Peugeot 206 1.9 d xtd does not start in cold

Hello, you will see, my car does not start in cold, it has new battery and new heater and I have proven that if energy comes to them, but in cold it costs him a lot to start if it starts, I have thought that perhaps it is the relay of the heaters, but I do not know that part of the engine is, if someone can help me Pliss!

It is in the motor compartment, the basis covered with a black plastic is green, and they reach it and leave more less an amount of 4 or 5 cables, if you do not find it you can segir the cable that reaches the ramp of the incondent spark plugs, or candles, to the blissful relay, anyway, try with a test lamp to see if it reaches current until the spark plugs.

Thanks friend, I already found the relay, it is just behind the battery compartment.
I have done the test with the lamp and if it has electricity that is lit 2 min or so, with which I think it would have to rule out the relay .. I do not know more that it can be because it only has a hard time starting in cold, what do you think it can be?

You can have problems with the starter engine or with some injector. You will have to try, you have a simple test heat the spark plugs and then pushing the car to see if it starts if the starter engine is immediately crushed.

You should check if you have diesel or an air intake. It is common in these engines that take air through the bombin that is next to the filter. With the kilometers to me I have given the case that the valves are step on and you have to make them adjustment.
