Engine swap no start issue

[Bradco02]

Long story short, I broke plug on previous engine and metal fell in cylinder piston and wall damage, bought used nine supposedly 73k miles, installed cranks but no start I did some checking and I know I did not put back ground to block on passenger side could it be this? Or other grounds I used my coils, new water pump and thermostat, besides ground where should I check, my previous engine worked so can’t be fuel pump, it sounds like no spark
