MK4 akl no start. Im seriously confused
 

Hello everyone, i drove my akl golf mk4 home and next day wouldnt start no matter what. Next day i continued to diagnose and suddenly it started right up without doing anything, took it for a spin and turned it off, had a hard time starting a couple times and then it wont start at all. I diagnosed that it doesent get spark. Ive replaced crankshaft pos sensor, ignition coil, ecu relay, ecu, checked all fuses and cleaned grounds. Not sure if it was a software issue or something else but vcds wouldnt show any codes and vcds wouldnt let read live data (the block in vcds was gray). Im really puzzled about what it could be. Sometimes fuel pump stays on after i try cranking until i take the key out.
Thanks for any ideas on what it could be.
