JEP Cherokee does not start

I have a Jeep Cherokee 2.5 TD VM Motor. A month ago I had to disassemble the cylakers to change the safety plugs. I have mounted it this week but the car does not start, because the diesel does not reach the injectors. My question is, why does Gasoil not reach the injectors if it reaches the injector pump?

First check if the pump brings manual unemployment and if it is not stuck and if it brings electronic coil but you must check the type of unemployment that it brings for that cause there can be no diesel in the injectors, if it is of line by cylinder I purge them go to the engine while opening one of elllas so that the air comes out.

Did you bleed the system?

Hello, I want to tell you that thanks to you the Jeep to start today and is very good. Thank you for your responses, colleagues.
