Others will pitch in for solutions to your problem... but here are my
suggestions...

- engine not running, manually turning the throttle... Do you hear a faint
clicking noise?... if not the throttle switch needs adjustment till you
hear the clicking noise.
- check all the vacuum hoses...
- check the AFM connector... pull it out, spray some carb cleaner on it and
reconnect.

good luck and report back,
