My 2006 ford f150 cranks but it wont start. I checked the fuel pump and its good as well as the sparks look good. I sprayed ether on the carburetor and not even that made the truck to start. The diagnostic computer shows these codes p0121-throttle/pedal position sensor a circuit range performance,p0221-throttle/pedal sensor/switch b circuit range performance,p2104-forced idle,p2106-forced limit power,p2111-throttle actuator controll system stuck open. The truck was driving fine and the next morning it didn't want to start. help please
