Hello, I am Jose Sebastian. Your automotive expert, It's a pleasure to me to attend your question. Thank you very much for trust in just answer.
Dear customer, does the engine turn over when you try to start it? Did you check with a purge of the injection system?
I would also like to know how this problem happened.
Dear customer I understand the problem you are experiencing, according to the symptoms there is a possibility that the problem is at the fuel injection level.
But fuel preheaters can also cause this kind of problem.
Let me explain the factors that a diesel engine needs to start properly: the first thing is good fuel pressure and high compression in the cylinders because as the diesel is a bit volatile it needs to spray at high pressure in the injectors and then be subjected to high compression in the cylinders.
But first of all they need to be preheated so that the fuel can give the first combustion and then the same temperature of the engine allows the good operation of the vehicle, the preheating is given by preheating spark plugs when they are not heating the fuel unfortunately the vehicle does not start.
But also a loss of injection pressure and a lack of compression of the cylinders can cause the vehicle not to start.
