Been researching on hella forums to figure this pesky issue out.
Keeping a log on Trello -

It's a public board, so feel free to add comments, I am sufficiently stuck!
Background: One random day a few weeks ago it started spinning during ignition which I thought was a little bit weird. But sometimes I was timid when turning the car on so I thought it might have been me. Then driving back late one night the car just cut off in the middle of the road. I was able to park it somewhere and get it towed. And since then it cranks but will not turn over. Will be checking for spark soon. But, you can look at the progress of the diagnostics on the log part of the board.
