Cranks no start cold day?

Posted this question before but I cannot find it. One cold day tried to start it it made a noise and died, then kept trying but didn't start, sounded like starter is bad or no compression. Left for another day, floored it and tried took forever but started, would idle fine without misfire but if u take your foot off would die. No codes at all. Pulled camshaft cover, and I am seeing the chain is not lined up based on what I know, also, the tensioner I believe is way out unless am mistaken, need your input on it. Only 94k and a chain stretch? Maybe, not sure. No codes no matter what. Took off intake and HPFP in case its stuck, compression was all 30psi across before I took everything off. Does not make sense, something happened all of. Sudden, don't know If it bent valves or just jumped time, can't see any indications from intake holes.
