NEED HELP 2006 chevy trailblazer relearn

[ayalamarcus5223]

I have a 2006 chevy trailblazer. I was installing a new radio and failed. I pulled some fuses when I had no power and now my car won't start. I turn the key power comes on but when I try to start it acts like a dead battery. Both the battery and ignition switch are good. Its like I set off a safety cut off

Hi and welcome.

Is this a stock or aftermarket radio? If the latter, did you use an interface adapter?

 

[ayalamarcus5223]

Is it just a plug with wires or does it have a "box"? If you have the make and model of it, that would help. Does your truck have Bose? Sounds like you either got the wrong harness or it was wired wrong. Did you try disconnecting it to see if the truck starts?

I did disconnect but no luck

Does the lock icon come on or flash when trying to start? I doubt very much adding a radio would activate VATS.

All the lights come on when I turn key on then they all turn off after 10 second but lock icon is present and they all blink

If security light goes out, it's not a VATS issue. You'll have to troubleshoot like all other No Crank situations.

This what happened to me. I installed a radio and same problem no start, all other lights worked. Check the main fuse under hood that may have blown. That's what happened to me anyway.
