'84 300D did not start this morning.... what happens when fuel "gels"???

This is my first experience with a diesel. I just started driving the '84 300D I bought only 3 days ago. So far I have had a pretty good experience, but not this morning.

Last night it was about +3 F out. I did not have the oppertunity to plug in the block heater. This morning when I turned they key, (after turning the key on & off about 4 times to get the glow plugs going multiple times), the motor would not even crank. I got nothing. Keep in mind, my battery is 2 days old, and has plenty of CCA's for this motor (1000).

Is this what happens when the fuel "gels"??? Like I said this is my first experience with a diesel. I would have at least expected the motor to turn over.

Any advise would help. Also, I was considering maybe doing the 20-30% mixture with kerosene. I have read about this. Would this help my problem??? I only ask because I do not have the option to plug in my all the time.


Thanks guys!!!

Sounds like the neutral safety switch. You got a good hunch there!
A way for jtoma878 to check this would be to put the gear selector in "N" or "P" and while turning the key to the start position, gently move the gear selector back and forth, staying near the "N" or "P" position. Of course it may just start if put in the "N" position.
