I just got my computer tuned with PCM For Less, but now my car doesn't turn on. I tried a buddy's computer, and boom...starts right up. I'll be sending it back to them, but what you think they did wrong...Maybe to much timing? Has anyone else had this problem? It's an OBDII computer by the way. Please give me your input on this.

Thanks

 

Does it turn over, and just not fire, or is it dead? Any chance you had them mess with the VATS system?
