Another CD Player with no power

Okay, i was putting my old system into my wife's 2003 Cavalier, ive installed 4 systems total, so i know my basics, but ive hit a wall this time, not so smooth of an installation. The factory cd player still gets sound when i hook it up, but when i put this Pioneer DEH-1400 in, it wont even turn on, and my amp doesnt power up either, im assuming the amp wont turn on if the cd player isnt getting power because of the remote wire (could be wrong) but yeah, ive checked teh fuses in the fuse box, in the cd player, and amp for the hell of it, all good, the fuse on my power cable for the amp is good too. PLEASE help

are you using a harness for the factory plug? If so, check the source you used for the switched lead; the factory plug doesn't have one.Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.

im using a harness i got from wal mart, just re wired with all the matching colors

what you mean switched lead, ive done this a few times, but someone just showed me and i self taught myself, so i need some explaining

the red wire from the stereo is the switched lead; power when the car is on; no power when the key is off; this is how the radio turns on and off with the key. The newer GM have a databus system that incorporates the radio; it keeps your radio on until you open a door and provides the chimes for seatbelts,headlights, keys leftin the ignition, etc. This signal is provided via a data wire; there is no switched 12v wire in that harness; you need to run a new one to either the fuse box or ingition harness. Life moves pretty fast; if you don't stop and look around once in a while; you could miss it.

any way you could give me some pics of this, some sort of tutorial, im always up for learning new things, and this is def. new. I would REALLY appreciate it, i can use all the help as possible, but let me get this straight, i have to run a new 12v wire, is this somthing i can get at wal-mart or do i need to go to my local radio stores, and also where would i run it to my fuse box, would that be easier than to the ignition harness, and which would you rather recommend? Is this somthing i need to solder in, or can it just be crimped in, or taped (knowing taped is the worst choice, just asking). But Thanks again for the help so far

i seen this thing at wal mart for 45.00 was somthing that had an addional hook up, that pluged into the car im assuming, and it said used to install an aftermarket cd player with stock adapter, or somthing along those lines, anyone know what im talking about?! Just wanted to know if it is what i need, if so that will save me a little bit of a headache. If your not sure ill find a link to it later, i dont have the time now. but thanks again

I don't think I'm the only one that's unclear.  Is Wal-Mart carrying modules now?  If you can post a link we can tell you more about it. My ex once told me I have a perfect face for radio.

It was like this, but about half the price. http://www.scosche.com/scosche_caraudio.aspx?CategoryID=89&ItemID=DCGM09B
