Hi Scotty, My Truck is having a problem starting after it reaches operating temperature. In the morning when it's bone cold it starts like a dream. But after I drive it and get it up to temp, if I stop and shut it off, I can't get it started? No check engine light. I got advice some someone that told me to change the Crank and Cam sensors. I did...no change. I'm going to change the fuel pump relay for the heck of it, it's easy enough. I believe I hear the fuel pump prime up consistently? Sometimes in my rage I might not be listening. ( : I have no trouble at any other time. Only when it reaches temp?
