Can you change spark plugs on a diesel?

It depends on what car or engine you have to decide how many. No diesels don't have spark plugs. Some have glow plugs. Not the same thing. Glow plugs are used to heat the cylinders. For quicker starting. On certain old diesels, yes. For example the IH farm tractor model M diesel made in the 1940's started on gasoline (with spark plugs) and switched over to diesel when the engine was warm (spark plugs not used at this point). That is true. But I didn't think about them. Most people today have never heard of a system like that. There was also engines with pony motors used to start the main engine. I learned the hard way. Not to stand in front of the arm. When you start the main. They can kick you.

Where is the firing order printed on a Mazda Bravo 2.5 diesel?

ok since it is a diesel it has no firing order ..diesels dont have spark plugs and they dont use a spark to combust they use compression because diesels are high compression and heat and glow plugs before it starts heat it..if it will not start it might be a glow plug issue or a injector issue if everything else works like it turns when you turn key
