360 Engine cranks but won't start

I am Del and thank you for everything. We drained the oil because my guy said even though I had not driven it I didn't want that oil in it for the break in. So we are gonna prime the oil tomorrow in the engine then get her going. You know I never even heard of manually priming the oil. I guess its because there is a ton of air pockets in the engine that you don't want to just start cranking on it without priming it first. Well if I can i will post a short video here tomorrow or pictures if that don't work. It was so weird though first the ECU went bad then the ballast resistor. Both have been replaced so lets keep our fingers crossed there are no leaks tomorrow. Probably just jinxed myself lol.
