Good morning, I have a problem that no one seem to be able to help me with so I thought I would come here,
I have an 09 f350, with a 6.4 diesel, when it get above 85 degrees out side the truck won't start , motor is warm ,but if it stays below 80 degrees, I can shut it off and it will start right up,it is only a problem on days when ambient temp is above 85, no codes and I have a friend that has a scan computer that can check everything, and its not throwing any codes , any ideas would be helpfull also where is the ambient temp sensor? ,its not behind right headlight and its not in mirror , thank you for your help.
