Hello.

If you are having hard starting in the morning the first thing I would check is the glow plugs. The glow plugs are meant to warm up the engine so that it can start properly, if they are worn or faulty then the motor can have starting issues such as the ones you are experiencing.

If you decide to get this fixed, I suggest getting some help from a qualified technician who can diagnose your hard start and make the necessary repairs.
