***update***

left battery unplugged for around 12 hours, hooked back up with JVC cd player attached and everything was good. Tried to install jvc cd player by putting mounting kit and all that in, which required unhooking cd player. After i hooked it back up i got the crazy sytem again. I unplugged the battery, hooked up the factory radio and tried again. with a battery charger on the battery, i get power in truck, but w/o it i get nothing. With charger on truck will not start. maybe unplug battery again for several hours with GM radio installed?
