Whenever there is no throttle movement, codes are set. You need to read the codes to get an idea of where the problem is.

It could be wrong/bad pedal, wrong/bad TAC module, wrong pedal-to-module harness, bad throttle body, broken wire, etc.

Are all the parts from the same vehicle?

I've seen people piece these systems together from Ebay to save money, and spend months trying to figure out they had the wrong combination of parts.

Hey, thanks for the help. I checked it out today. Heres what i noticed. First the battery was dead. so after charging the batt. It started right up. It ran, and the throttle worked. I shut it off. checked some things out. Started it again. Every thing worked. This time I let it run till it died. I then started it again but this time the throttle did not work. But the check engine light was on now.
So if the engine stalls out and dies causing a code it will disable the throttle?
