So, I drove my car all day yesterday, battery is charged, everything is in working order. Overnight we get freezing rain and its about 15 degrees. Won't start. Cranks and cranks. I let the glow plug warm till after the light goes out. I use the plugs a few times before cranking. I attach a booster charger with the jumper cable attachments. Its turning faster and souonds like its running while it cranks but it just won't start.

I don't want to run the battery down so I leave it alone, but I would like it to start hopefully by Wednesday! Am I missing something? Does this happen sometimes or is it a sign there is a wink link in the charging/ignition system?

Here she is today:
