Drove my 300 Sd 300 miles yesterday no problems....

I tried to start it this morning would not turn over..
I tried to jump start it... nothing..

The lights work and the gages move and the glow plug light comes on ..,, but it wont turn over


Thanks Guys..

Sorry I didn't describe my problem clearer,, But I am late for work.. Spent the AM fiddling with the SD...
