Okay, usually on cold mornings my truck Just fires up first turn of the key, no pumping on the gas, nothing. This morning, My truck did not start.. I pumped on the gas, and it tried once, but nothing. It turns over, but never tries to run.

I pulled my fuel line off of my carb, and pumped my gas; And no gas squirted out.
I put gas into my carb, and my truck starts and dies VERY quickly.
What does this sound like to you guys?
