    00 4.3 vortex won’t start unless you pour gas in the throttle. New pump spark plugs dirty. Spark plugs the problem?

    won’t start unless you pour gas in the throttle ….
    Certainly sounds like a fuel delivery issue.
    You state a new pump installed, I assume you mean a fuel pump.
    Have you tested fuel pressure at the rail?
    Have you confirmed fuel injectors are functional and are flowing fuel at the correct volume?
    Have you checked / tested fuel pressure regulator for proper operation?
