Hi, I have an 09 civic, automatic transmission with 141,000m. I brought my car to the mechanic to get my ac fixed. They pulled it into the garage, snd started to diagnose where the ac problem was to make sure it was my compressor. (Messing with fuses and stuff) But when they tried to start the car again it didnt start. I've never had any issues with it starting in the pass. It will crank but wont start, and they cant connect to the computer to pull any codes from it!

check the fuses

Also check grounds, you need both +12 volts and a good ground at the OBD-II connector.
