Check injectors, fuel filter, fuel rail, timing, fuel lines and now the starter. I'll even suggest the fuel regulator cus if thats stuck in the open position your fuel pressure will be little to none. A clog sounds more like the problem though. One question though...Don't you know that pumping the gas pedal "thinking" it'll give the engine more gas doesn't do anything at all? I mean come on this is a fuel injected vehicle, not some ancient carburated domestic pos. All your doing is flaping the throttle which does nothing to help cus the IAC valve (if working properly) will be able to supply the engine with enough air and signal the ECU to send proper amount of fuel to start the engine. And the ECU doesn't read the TPS for fuel supply purposes until the engine is fully running. So , pumping that gas pedal is pointless...
