Disconnect the fuel line off the carb then turn the starter over. There should be gas shoot out. If not your fuel pump may be shot. have you ever changed the fuel filter? If its plugged it will not work.
What have you checked so far ? Is it getting spark to the plugs ? Can you spray starting fluid into the throttle body and get it to start ? Have you checked fuel pressure at the injectors ?
You need to do a pressure test on the carb, this will tell you if the inlet needle is leaking, it is also important that the metering lever onto the needle is not set too high, on the metering side of the carb the gasket goes against the carb body first to act as a spacer to the metering diaphram.
make sure your shut off valve is working right in fuel line, pull off the hose @ carb and see if you have fuel there, then pull float bowl off and see if gas is making it into there,move float up and down and see if fuel drips out of carb with float in down position, also check to see if you have a electric solenoid in float bowl, if so this has to open up with power on it. If it does'nt open you won't get any fuel in the bowl, my guess is either that or your needle is sticking closed....good luck
Check all of the fuel lines very carefully for breaks or cracks in the fuel lines, especially between the fuel tank and the fuel pump.
If the fuel lines are all in good condition then you can safely assume that the problem is in the fuel pump and you will need to replace it. (If the fuel pump is in really bad shape the engine oil on the end of the engine oil dip-stick will smell like fuel)
Ok then if it's a carburated engine you'll need to open the fuel filter and carburator itself and clean them up, as you know fuel evaporates by passage of time and they leave little hard particles that can clog fuel filer and/or carburator, you can open and wash them with gasoline, at the mean time it's a good idea to change spark plugs first hand, it might solve the problem.
Hope it helps and please don't forget to rate the answer it helps me, thanks!
your getting back into my era now but try holding down the acc. pedal when cranking if this helps somewhat then the carb is leaking fuel into the cylinders or the choke is sticking closed is it smoking black out the tail pipe? this would be from excessive fuel -- fuel evaporation can take place when a fuel line is to close to a heat source- we had vapor lock common to older cars usually when running down the road tho. another stretch is an ignition coil which will weaken with heat. oh, is the timing correct? advancing properly? great car i hope this helps!
