Do you know if the check engine light comes on with the key in the on position?

Customer: replied 1 year ago.
it is
Expert:  Amedee replied 1 year ago.

Ok, then your next step is to check to see if pin 16 of the diagnostic connector under the dash has battery voltage on it and to see if the throttle position sensor on the side of the throttle body is getting a 5 volt reference with the key on.
