Late work problem

Selamünaleyküm friends, I have a problem, my vehicle partner adventure 2.0, when he waited for a day or two in the cold, he worked late, worked late, stopped or not working, went to the master, said that spark plugs could be a solid pump, injectors could be said, I didn't believe much, the next day, I opened the hood and started pumping with the hand pump the next day without pumping. I did a little bit of diesel oil from the filter box, I started to work more easily. My problem may be related to the filter or the filter box.

I think you got air because you said it was leaking. There is something called spider hose (on the handlebar part). If you change it, the problem seems to be solved.

Thank you for the information you provided.

It is necessary to have the hoses checked by my teacher.

I'm going to have a master in oil care
