Hey Guys,
Thanks for the advice, tips and commiseration.....
My battery was dead after all. Got a new one this morn, and after some minor messing around with Marvel Mystery Oil and adding more fresh regular diesel it STARTED. Glow plugs, starter, fuel lines are FINE! Whew....
Now onto other issues and other forums to get my Beloved White '85 300D Perfect again. She only has 175K miles and should last many more years. I've been driving her here and there all day just for the joy of it, and to listen to one of my favorite sounds, The Diesel Engine.
