Installed my 15% Alta pulley today and all went okay... After much ado, I finished and after unplugging and replugging the ecu and ignition stuff because I got the EML light soon after starting it, I eventually got it work wonderfully. And on the ride home I didn't want to turn the radio on because I wanted to just listen for any problems and all that. Well after a while that got boring and tried turning it on, but it doesn't turn on?! The lights work on all the button, but the screen doesn't light up and doesn't do anything else? So does anyone suggest anything?

Thanks

 

Its broke?
