Question
Back in 2004 I purchases a CD player from Best Buy and had them install it for me.  They said that in 2000 Cavaliers the computer of the vehicle was in the factory stereo and they would have to mount the old stereo in my trunk. Not too long after I did that I noticed issues when it came to starting my car.
(Please keep in mind that I am a girl and dont know all the correct motor lingo.)  My car would have problems starting. When I would turn the key it would make noise like it was trying to start, but would hardly start on its first try.  Sometimes after you get the car started the Theft System and the light right next to it (I cant remember right off the top of my head) light up, but this is only SOMETIMES.  Other times after you get it started no light come on at all.  We have taken the car to the shop multiple times and they cant tell us anything due to no dashboard symbols indicate a problem.
My question is, do you think that something could be wrong with the factory stereo that is mounted in the trunk?  Have you heard of this problem before?  Please let me know if this sounds like it’s the problem.

(I know you are unable to give me an answer as you have not seen my car, but though it is 10 years old, I have taken very good care of it.  The only maim problem Ive ever had was with the air conditioner.)

Answer
I see this  problem every day, the problem is many  the idea of the radio in the trunk is the most dummest i dea i seen ,
the other mistake was to allow kids out of high school doing the installation

go back and tell them to put the factory stereo back the way it was, remove all cables they run

unplug the battery and wait 30 minutes, the vehicle will go back to factory
and everything will work again
drive it for a few weeks,
if something happends go to the mechanic again most likely that is not going to be the case

after a few week that the vehicle i working ok  ask me again how to install your aftemarket radio  back n the vehicle

there will be  no radio in the trunk, it will be at home in a closet
