No throttle?
#2
What year and which engine? Does the engine start and idle normally, just no speed up when throttle is opened? Check for codes. If it is a "Drive by Wire" system, it may have been forced into one of the "no run" modes, such as "Forced Engine Idle", or "Forced Engine Shutdown".

The first is self-explanatory. The second means the drive motor is not responding to computer commands correctly. I believe if the cause were in the Throttle Pedal Sensor, a code would say that, in addition. If no other instrument cluster lights are staying on, namely the "wrench" and/or ABS, the trouble likely lies with the Throttle Actuator Drive Motor. If no other lights on, I would replace the Throttle Body Assembly; I don't believe the motor is serviced separately, but you could check. imps

Throttle positioning sensor
Where the TPS attaches to the throttle body is there a spring the goes inside the throttle body where the TPS mounts to it? I'm thinking there should be a spring but I'm not seeingone. If there is supposed to be a spring can you tell me where I can get one and what size it might should be? Thanks

On my 2010 it's throttle by wire. I put in a new TPS sensor and a new gas pedal. You may need to take your gas pedal off (unplug the plugs first) then undo the torx screws on the side, remove the cover and clean out the contact surfaces. Reassemble and see if that helps. Or get a new throttle body as it may be heat soak damaged. ROCKAUTO.com has them for a good price.

During that one second test, PCM compares Throttle Position Sensor output to determine no fault is present. If a fault is detected, the engine is put into Forced Idle only condition.
Something is screwed up, either the TPS is improperly attached, it's electrical connector not making contact, or the TPS itself is faulty. The other possibility is that the servo drive motor is faulty. You cannot rebuild/re-work the Throttle Body yourself. I have done it, and I can tell you it may drive you nuts trying.

I'm leaning towards it being the TPS. The new one in ordered from Ebay does not have a spring inside it. I have several other TPS for earlier model Mustangs and out of curiosity I opened one and yes it has a spring. Attached is the before / after of the TPS.
