HELP - Won't Crank "engine temp" light 15deg F in Maine

[StrongCo]

Noob here...recently bought a 1994 F250 4x4 w/ 7.3 IDI turbo diesel w/ fisher MM plow to plow my private drive in Maine....

Its been starting and plowing fine (unplugged w/o block heater) while the temps have been between 30-45 degrees F and last night it was going to be in the mid-teens and had snowed all day so I plugged it in overnight....

This morning at ~5:45am
Put key in - let glow plugs engage ~30sec then they turn out - go to turn over and nothing... just the ENGINE TEMP light comes on....?

Is it indicating too cold or too hot?
the block heater "plug" is working

But it will not crank does not even try....Any assistance is appreciated as I could have burned that thing to the ground I was so pissed this morning,,, but it doesn't take long to cool off in Maine and I'm back to my senses

Thanks and glad to be part of the forum.

Batteries good? Bump for ya.

Did you try to cycle the glow plugs twice and do you hear them buzzing when the "wait to start" light is on?

I don't know if there is a sensor to stop it from starting when it's too cold, but it was 12 degrees F this morning and she started fine after being plugged in over night. Sounds like a dead battery, did you try to jump it?

Auto transmission or shifty?

if it wont crank...its one of five things more than likely.....

Batteries

Starter

Starter relay

Fuse

Wiring

Agreed.

Did some work last night - but was cold as Sh*t! Looking like Battery or Starter - will solve or eliminate those (2) items Friday or Sat. morning....


Thanks to all.
