I am new here and am very excited about my new project. 1984 300D. It is hard to start in the morning unless the block heater is plugged in. Glow Plug problem I guess. Where do I start looking? The glow plug light on the dash does not light up when the key is turned on. Is there a fuse to check? How do I test the relay? What is the most common problem. Warn out plugs, Bad relay timer? Can you please tell me what and how to diagnose this system?
Thanks
Foxhole
