Gas pedal does not working after replacing brake booster and Master cylinder

Hello
My name is Dave, it sounds to me like the most likely cause would be accidental unplugging of the accelerator pedal, most probably while connecting or disconnecting the brake pedal. If you look under the dash you should see a plug that plugs into the pedal, look for it to be unplugged or the wires being damaged. I hope this helps and thanks for using 2CarPros, let us know if we can assist you further.

Yep I agree with Motor Master. Here is a diagram of what we are talking about below. Check out the diagrams (below). Please let us know what you find.
