Under the hood, under the brake master cylinder. There is a label on the inside of the fuse block cover. Replace the one that says "CIG LTR" it's also the power link for the ODBII port. After you replace that fuse, your code scanner will recognize that it is hooked up.

There's more than one fuse bos. Look under hood or under dash for other fuses. Otherwise you have a bad ground or wire shorted somewhere. Check the owners manual for additional fuse boxes is available.

The OBDII connector is on the same circuit as the cigarette lighter. A lot of times a cell phone charger or other device will blow the fuse and cause the scanner not to power on or communicate. I would just double check the cigarette lighter fuse. Also, maybe try a different place. Pep Boys isn't exactly known for hiring the most qualified technicians.
As or the remote start. It isn't working because of the check engine light. For some reason on late model GM vehicles, having the check engine light on disables the remote start system. Once the problem is repaired and the codes cleared the remote start will work again.

Make sure your cigarette lighter works, many car makers use the cigarette lighter circuit to power the OBDII connector. Check the fuse.
