I've hade my 1996 7.3 Powerstroke for a few years now. It has always started well in the cold Wyoming mornings. However, this fall she doesn't seem to want to do so well. It's 34 degrees this morning and she still won't wake up. I let the gp cycle a good 30-45 seconds. It will turn over and white smoke will come out but won't fire up. Earlier this week it would do this but then it would fire after a few (4-5) tries. And after I get it fired once, I could shut it off and it will light right back up and start great the rest of the day. Any ideas?

 

What oil are you running?

 

I've got the same problem I would sure like to see what everyone thinks
