gas pedal not working????
« on: December 23, 2012, 08:56:12 AM »
I got back from a 2 hour drive, unloaded truck, and then cleaned it out. It sat for about 2 hours. I went to go to store and the gas pedal is not working; it physically works, but doesn't have any effect on giving fuel to motor. Hoping to go out of town day after Christmas. OOPS, its a 2001 F250 with 7.3. I just had LCD, in Livermore, put a tuner, exhuast, and intake on it about 2 months ago, but they are closed for the weekend!!!

May be the idle validation switch not working.  You should hear a click when the pedal is depressed and another click when the pedal returns to idle position.  If it is out of adjustment then it does not reset and the PCM does not get a signal that the throttle pedal is being depressed, the engine stays at idle.  There is a microswitch that the pedal linkage operates that can be adjusted by bending or the switch itself may be sticking.  Watch the pedal linkage as you depress and release the throttle pedal, if the linkage completely clears the microswitch then it is sticking.  Spray it with electrical contact cleaner (from auto parts house or Radio Shack), if you get lucky, it will free up and operate.  The other condition is that the linkage does not completely clear the microswitch and the switch does not have full travel to release.  You have to bend the linkage to allow the switch enough travel to reset.  You should be able to hear a click on depressing and releasing the pedal.  You have to hear the click several times before declaring a fix.  If these two fixes don't work you need to go to Ford, bend over and buy another complete throttle pedal assembly, the microswitch is not available individually.$$$$

TPs gives erratic throttle action or no full throttle not no throttle response.
