I think your engine has a vacuum leak, check all of your hoses, and carb fittings.
If your engine cannot get enough vacuum it will not be able to draw enough fuel to run.

    Every Engine relies on Vacuum to draw fuel or fuel air mixture in.
    Fuel injected or otherwise.
    If your vehicle has a vacuum leak then it will act like yours is acting.
    Just a shot in the dark over the blind internet ;-)

1993 chevrolet silverado 1500 will not start has new filter and pump can spray fuel in to it will start then dies when it runs out of the fuel sprayed it it

It sounds like your injectors are not firing which could be a crank signal problem or wiring,distributor pickup coil problem or a computer problem.One wire to your injector should be pink this is the power wire it should have around 11.5-12 volts with the key on. The other wire is ground that the computer uses to fire the injector which you can check with a good test light hooked to voltage. and work back from that point if you have neither at the injector.

Hesitates at wide open throttle

Could be as simple as new wires. Try turning on the truck at night and check to see if your wires are not arching to the engine block/manifold. Trust me if the wires are bad you'll see it at night. If they are, they need to be replaced along with the spark plugs as this will foul the plugs because of impropper detonation.
