Truck wont start

[popsthebuilder]

I'm pretty sure the choke is disabled on my 73 c20 350 th400, but this morning is the first time that I can't get it to fire up at all. Turns over just fine. I am officially late. It's kinda chilly (around 50 deg.) but not too bad. Should I walk to the store and see if they have a can of starter fluid? What can I do to get her fired up? Any relevant suggestions would be greatly appreciated.

     Since you said it turns over, the next step is to see if you have spark at the spark plugs.  Anything else would be a guessing game.
