Best place to start is diagnostics. If you can get it on Lexia or Diagbox, that should begin to give some indication with stored faults.

Could be worth some easy start to see.if you can get her running again

Given what you have said already, "..pressed all the wiring I could see.." would suggest that you may have a loose connection / plug or some dirt in one of the connectors if not a loose or broken wire wherever it was that you were poking about!

A systematic check and clean up of all your connectors with some electrical contact cleaner may be worth a shot in the first instance - put it this way - it won't make things worse than they are. Then get it on a Lexia for a global test, clear the faults, and re-test. Any faults that remain can be accepted as 'new' temporary or permanent faults and will form the basis of where to start.
