why won't my accelorator pedal work? car cranks over but will not stay running

What is your question?

replaced the bad alternator. cranks over but will start. the accelorator/gas pedal will not work there is no throttle. i disconnected the tps connector, now the cars stays running so i replaced the tps sensor, and still the same thing. cranks but does not start. i also replaced the mass flow sensor and still same thing. I checdked all the fuses and relays. i had the battey checked and certified as a good battery full charge ??????????
