Re: Fuel pump is working but still not getting gas and...
Just because the fuel pump is working doesn't mean it's supplying the correct pressure. You need to do a fuel pressure test to rule out the fuel pump. Change the fuel filter too if it is inline.
If memory serves, pressure should be 55-62psi with KOEO. Other things to check would be the fuel pressure regulator and related components.If memory serves, pressure should be 55-62psi with KOEO. Other things to check would be the fuel pressure regulator and related components.

It could be. Since you have a carburetor, you must have a mechanical fuel pump on the engine? Only some imports with carburetors had an electrical pump.
If your filter is in the line just before the carburetor, take the line off at the filter, then crank the engine over to see if the pump is working. Mechanical fuel pumps will pump gas when the engine is cranking or running. Use a jar or can to catch the gas. If pump is working, fuel will come out in small spurts. It's not under high pressure- carbs don't need high pressure. If no gas comes out of the line, you probably need a new fuel pump. If the pump is working, it could be the filter, but could also be the needle valve and seat at the carb's fuel inlet. Sometimes they get stuck closed and won't let gas into the carburetor.
I would have the fuel pump checked, sounds like you are not getting any gas.
Turn the key to the ON position and listen for the pump to hum, if there is no hum your pump is definitely shot or not getting power.
If you hear a hum, you may have a blockage... try a fuel treatment if you want to start simple. If that doesn't work you will need to pull the pump and see if it is actually pumping the fuel
was the engine getting fuel or was their no spark ----need to establish if fuel or ignition problem ---running out of fuel may have damaged pump -deadspot -overheat ---problem with relay need to check and test the system ---
When you turn the key to on, not start, the pump should come on for about two seconds and then shut off. It won't come back on until the car is being cranked. Then it should be on, and remain on when the car is running. If the car won't start, and you suspect a fuel or fuel pump problem, the best way to check it is have the fuel pressure tested. Correct pressure at the injectors is critical for the engine to get enough gas to run proper. If you don't want the pressure test, and only want to verify pump is working, then break into the fuel line somewhere convenient and see if gas spurts out when you are cranking the engine over. If it does, pump is working. If no gas comes out, line is plugged or pump is not working. To test for power to the pump, a mechanic would check for power at the fuel pump connector while the engine was being cranked.
Looks like you got spark, and gas in the throttle body made it fire: nice work.
Sounds like your fuel pump is out or the wiring is not turning it on. One way to be sure is to set a spare battery near the tank and hot wire the pump with jumper wires. Or if you have a voltmeter check for voltage at the fuel pump connector while the truck is cranking.. If the pump is working and getting gas to the engine, see if the injectors are pulsing. A good idea to check fuel pressure if the pump is working.
There should be a small shrader valve on the fuel rail just remove the cap and press in on the valve if fuel shoots out under pressure the fuel pump is working if no fuel comes out, check the fuel pump relay and fuel pump fuse, if both of those check out ok the fuel pump is probably bad and will require removal of the gas tank to access the pump for further diagnosis....
Can you here the fuel pump kick on? If not you will have to replace it. If the car has alot of miles and fuel filter was never changed then the fuel pump will work harder and wear out. Pump located in tank.
fuel pump......... smack the gas tank while cranking should start check the fuel pump relay you can jump the two big prongs on this that is the fuel pump good luck
