You mention you changed and checked spark plugs. But you also mention you have a CDI? CDI signifies you have a Diesel engine and diesel engines do not have spark plugs....Please clarify, maybe you changed the glow plugs? Did you check the wiring harness for the glow plugs?

Yes, it's CDI. All diesel engines have spark plugs, but they have other principles than those on gasoline.

Diesels don't have spark plugs.
