So I've been working on my mother's V70xc. Was trying to replace the radiator fan because it would never shut off and kept running the battery down.

so I pulled it out to get the model number. Hadn't replaced it and needed to move the car real quick.

so now it wont start. I plugged I. The obd2 and it said it was a serious issue with the TCV. I realized I had unplugged the vacuum line to it by accident. I made the mistake of clearing the computer data so it wont give me the code anymore, and I can't reset the check engine light. Is there some safety reset, or have I blown the car up? Help!

 

The starter is going bad so it was something else
