Expert:  Amedee replied 6 months ago.
Thank you for the VIN! Does the engine start and run? Does the check engine light come on with the key on for a bulb check?
Customer: replied 6 months ago.
Yes, the engine starts and runs perfect and the check engine light comes on once the engine is running.

there is no popower is down to pin 16, in fact there is no power to pin 16.
Expert:  Amedee replied 6 months ago.
Ok, lets start by checking the 15 amp CIG LTR fuse located in the underhood fuse block. This fuse supplies power to pin 16 of the data link connector. If this fuse is good, then check to be sure this fuse has power on it with the key on. If so and there is still no power to pin 16 of the DLC then you just have an open or a break in the wiring between that fuse and the data link connector. Here is a wiring diagram.
