Don't know if this helps but I had that exact same problem with my 180.
It was turning over and not starting
I had the battery hooked up to a van

, took off fuel line plenty of fuel being pumped in, kept turning and turning but wouldn't fire
The problem for me lead back to me messing with the wiring loom.
I accidentally brushed off some sensor?? don't know what it was for, it looked OK from distance, only when I reached down it was a bit loose (bad connection)
Then I turned and she fired up first turn
Image below shows roughly where plug is
It's worth double checking all plugs and sensors
