[QUOTE="bobcatguy, post: 102299, member: 11457"] So to update: After paying the tech to come out and guess, I went ahead and changed the suction control valve that I sourced from the UK. That didn't fix the problem. The next best guess by the tech is that the high pressure pump is bad. Now wouldn't someone think that a Deere technician could do better than guess as to which part is the problem? I'm now looking into the Pressure Relieve Valve on the high pressure fuel rail. As I understand it, if the PRV sticks open which is fairly common on some diesel trucks, it can cause the same no start situation because the rail can't build pressure. Now mind you the tech was there, saw that it wasn't building pressure and immediately went to the SCV or HPFP without doing any sort of verification as to whether the relief valve was bypassing fuel. I'm not sure why I paid them. I will report back. [/QUOTE]
