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

Try turning your ignition and removing your ground cable from your battery. This will reset the computer in the truck and clear your trouble codes! If it works it didn't fix your problem but maybe you can at least drive it to a service center.

I took it to the dealer and the problem was the battery. That is weird I would never suspect that the battery could do that! Thanks for the help

That is certainly strange. Was there any strange instrumentation activity during the cranking?

Not really, to me it looked like a fuel pump problem. They told me that the battery had a burn cell and that it was causing problems.

Totally confusing? Glad you have it resolved, would be my last choice of answers.
