Engine cranks but does not start, no spark

Engine was starting just fine a few days ago, battery drained so I decided to replace my crankshaft sensor camshaft sensor and o2 sensors. Because I had codes for them. Changed them tried to jump start didn’t work went a got a new battery to see if that was why than nothing. Then I find out ignition coils are getting no spark. Only happened after changing crankshaft sensor. Really stumped because I have no idea what happened it was running mint before battery drained. I don’t know how but it did start once but it was jumping RPMs up to around 1,500 then it would start to drop to stalling out and it would keep jumping up 1,500 until it shut off and now it won’t start at all. Just cranks no start.
