7.3 crank over no start

[big hauss]

I have a 2000 F-350 7.3L international. For the past three days the daytime high has been in the fortys or lower and windy. I plug my truck up at night and cranks just fine then i drive it to work and let it sit for 8 hours when i go to crank it up it will turn over but not crank. any ideas thank you in advanced. It will hit immediately when either fumes get near it. i have noticed smoke during cranking but after it is idleing there is no more smoke or rough idle.

You need to check your glow plug relay for operating properly and test your glow plugs.

I checked the glow plug solenoid this evening and even with the switch off it read 0 volts on the left hand terminal so i turned the switch on and it read 0 on the rite hand terminal while the glow plugs were heating up. thanks my next question is should i replace the relay in the fuse box also or just the solenoid
