Well, I,ve just had it running. Was charging the battery today. Just put it back on , turned the key and off it went.
Engine fault light was on, read the codes and got one for cam sensor. Then realised the cam sensor was sat on the seat beside me.

Put it back on and plugged it in, turned the key and it would start. Took the cam sensor off again and tried again but it still didnt start.
So Im now as confused as ever.

It did sound ok though when it was running.
