Yeah but he ran it ALL THE WAY out. It needed all six bled.

 

My old man ran his '02 bone dry one day. His fuel gauge gave up the ghost and he didnt realize it. (common issue on later model 2nd gens)

Bled everything at the VP, then cracked the first injector. Decided to give it a go and it fired up on bleeding just one.

That was about 20,000 miles ago and the VP is still alive. I think he got lucky.

 

Mine has been compleatly dry two times and I just cracked three lines.

 

As long as the pump is getting fuel into it, and you have a 2-3 lines cracked it will pump the fuel up and fire. Once its running the pump will push the air out of the other 3. I don't think it matters if you run out completely or just gelled up, the truck will start if you have fuel at the pump, and good enough batteries to spin it until it fires. Done lots of big truck like that, and there is no way to bleed those pumps or injectors. Just fill the filter and pray it takes, lol.
