I did let the glow plugs heat up when I went to start it but I did not have the truck lugged in over night. It started right away. Today, I have the problem described in the first post up to about 65*F. Finding a way to address a symptom does not fix the problem. I want to know what the problem is so that I can fix it without throwing moeny away on un-needed new parts.
