So I just installed a new head unit and bypassed the factory amp. Everything went well the speakers all worked and sounded good. Left the stereo on for 40 minutes while I put the car back together. Then I noticed the music stopped to I tried to start the car. Heard no clicks or anything. Just a weird buzzing near the intake beside maf. The obc and light work. The stereo doesn't light up and car wont crank, fuel guage moves when I put it to the on position. So what's wrong. Should I try checking fuses then looking to find all the grounds?
Also there was a memory wire the po had cut off to radio. So I connected that to the new head unit. What's wrong? Can someone give me a order in how to diagnose it?
