If you're still having issues and you suspect fuel delivery, or no fuel in bowl, or
you just want to eliminate fuel in the bowl before trying to start it. Heres a link to show how to check the float level with the vehicle running. This would insure the fuel level in the bowl is correct and you can use the same gauge to see if theres fuel in the bowl after the truck has set for a while.

I used this style of gauge when I use to work on the computer controlled quadrajets. Hope this helps
