Bowls in carb dry, Vapor lock?

[Snosh]

I have a 78 K10 4x4 with an Edlebrock 4 barrel Carb

Truck recently died on me while driving, I put a new fuel pump on it. Still won’t start, bowls in the carb are dry so my dad was filling them with gas thinking it could be vapor locked. We got it running this way but we have done this 6-8 times already, if it was vapor locked shouldn’t it be worked out by now? Could it be that something in the carburetor is sticking? And if that was the case would I just need to have the carb rebuilt?

Also we pulled the line that goes from the fuel pump to the carb and fuel is coming out, so we know the carb is getting fuel. We also tested for spark and that is also working fine. It tried to start when we used starting fluid but it never actually did.

Any help would be appreciated! Thank you in advance.

The valve that fills the float bowls is run by the floats.  Think of a toilet tank.  No fuel means:

1) floats are sunk.  They can leak and not float anymore.  Fix is float replacement.

2) valves stuck shut.  Can happen if the truck sits a while and the fuel turns to varnish.

3) valves clogged up with guck.  Can happen with a load of dirty fuel, or an old/original tank rusting internally.

Sounds to me like the valves are clogged with guck.  Open it up, clean them out, inspect all, make sure the floats in fact float, adjust float height, replace fuel filter, reassemble.

P.S.  Correction.  Forget "floats are sunk".  That would make gas flow all the time, overfill the bowls; the truck would run richer than a cob, and mileage would be horrible.  But the floats could be stuck in the UP position, keeping the valve shut off.
