Welcome to the fest!

Pumping the gas pedal does nothing. These cars are fuel injected and don't have an accelerator pump. You probably have a bad check valve in the fuel line or a leaking injector. The car should maintain fuel pressure long after it's turned off. If it leaks back, or leaks into one or more of the cylinders, it will be hard to start. If it leaks back, the system has to repressurize before the injectors get enough fuel to spray into the intake. If the injectors are leaking, it will be hard to start because one or more of the cylinders will be flooded. In that case opening the throttle and keeping it open during start-up is the way to go, not pumping it.
