I wouldn’t jumper the relay. Just turn key on until “wait” light goes out. Turn key off. Immediately turn back on. Do this 3 times then crank.
You don’t need a camera about the smoke. It will look like a gasser with a severe blown head gasket- TONS of white smoke that smell like diesel fuel comes out the pipe to the point as a gasoline mechanic you will get nervous.
Remember : Diesels, white exhaust smoke is either unburned diesel fuel or coolant burning in the cylinder and the identifier is the smell - coolant or diesel smell.
Cold starts it is common and hurts nothing to have the white smoke from diesel - it just tells you you’re not preheating enough. Also diesels never run “rich” or “lean” they don’t idle if lean and rich just puts out white smoke when engine is cold or black smoke when warmed up. Lack of air flow like boost loss creates black because it is “lean on airflow”
Here is a video of a tired old engine that needs its timing adjusted. The smoke is unburned fuel and when he unplugs the coolant temp sensor the computer takes that as super cold and maxes out timing advancement enough to clear up the smoke. Not saying you should do this, just so you see the smoke we are talking about.
