I had a Honda dropped off this afternoon because it had run out of fuel, the owner refilled and it wouldn't start. I went through the obvious tests, check it has spark put in new plug,pull the air filter and squirt starter fluid in and not a sign of it starting. I then decided to empty the tank ( he assures me it is unleaded 91) and I immediately thought the colour looked wrong. It was a yellowish colour and against the 91 I have here which is an orange colour. Anyway I got it running on my fuel and a new plug ( I believe the diesel has killed the plug) but I am interested to know if there is a simple way to test diesel. When I tip the container to pour the fuel, it has a bluish tinge which is why I think it is diesel. The owner says no way but I have to disagree with him. Any thoughts?
