A good choice would be to get a cheap automotive pressure gauge. 
(can you still buy those that measure both fuel pressure and 
manifold vacuum?) Insert it in your fuel line and have someone 
crank the starter. The gauge should go up to something like 3-5 psi.

If it doesn't, you may need to check the pump, or the gas may not 
be making it to the pump. 

My guess is that the gas tank is full of road dirt because the 
overflow hose is broken off. This has clogged the outlet screen in 
the fuel pump with dirt and the gas can't get out of the tank.

You can take to fuel sender out of the top of the tank and look 
down there with a flashlight. You SHOULD see a clean tank bottom 
with a brass filter "sock" sticking up about 3" from the bottom.

You can test the flow by taking the hose off the bottom of the tank. 
You should get a pencil sized stream that flows alarmingly fast. If it 
just dribbles, that's at least part of your problem.
