I have a 1979 300SD with 256,000 miles on it. I haven't used it much as I have the wagon as a daily driver. It starts fine cold after i replaced the one bad glow plug (it only needed #3 and it's the easiest to replace), and starts fine when warm. If i start it cold and only go a very short distance, the glow plug relay assumes it's warmed up and it won't re-start unless I either wait until it's dead cold or i jump the glow plugs. Has anyone fooled around with adding a resistor or something to the temp sensor to let a tired engine start easier?
