Jeep wont crank or start

I have a 2004 jeep liberty with a 3.7 v6 in it , blew head gasket fixed head gasket now wont start up again or crank

My girlfriend drove my jeep with a ripped heater hose and blew the head gasket , I was able to get it home and I repaired the heater hose and replaced the head gasketgasket, but now it won't start anymore , it cranked a few times and started roughly and now it doesn't even crank , I'm replacing the spark plugs that are caked in oil , will is the spark the real issue here or something much worse?

pray it didn't break other things inside the engine. Do a wet and dry compression test of all cylinders first, and if it's OK, try this video https://www.youtube.com/watch?v=064Ilsz8Fzg
