If this was a fuel delivery issue, why wouldn't it start if I spray a little fuel directly into the carbs? I would imagine that would get the truck to run for 30 seconds or so..

I do have 0 gauge wire for ground as well as to the starter. It seems to be charging very well. It also helps that I keep the battery on a trickle charger too...

I will check the fuel system. I will disconnect the fuel line going to the carbs and see if my fuel pump is pumping fuel when I crank the motor. I expect to see fuel pumping... That way we could at least cross the fuel pump off the list.

As for the fuel itself... it is very clean and fresh. The tank looks brand new. I be this restoration was done a year or two ago... Again, the truck fired up and ran with no problem or struggle.
