Power problem i have the wiring harness hooked up correctly, no fuse blown, but still no power what should i do

1.) a fried CPU (the cars computer)
2.) a lot of blown fuses in the fuse box under the hood
3.) a lot of burnt wiring in the harness.

hopefully just the fuses.. use this video to help you check the fuses. Its a free youtube vid not mine but correct non the less.

Apparently, you have no power at the 12 volt battery/memory wire at the radio harness of the vehicle. This wire is white with blue in color.
Also, based upon your description, you have connected the battery/memory wire and the accessory wire of the radio to the 12 volt accessory (switched) wire of the vehicle. This wire is white with red in color.
Check the radio/ stereo fuse of the car. You may have blown the fuse during your installation.
You have no memory at the radio because when you turn off the key, you lose all power to the radio.
Also, I mentioned the wire colors just in case you used an aftermarket radio wiring harness. Make sure that the yellow from the Pioneer unit is going to the battery power source and, the red of the Pioneer is going to the switched power source.

I would suggest checking your fuses could have blown them. or check your battery for cracks this isnt good , but worst case you would need a new battery or wiring harness but first step check the fuses then go from there

Ok, just so I get this right. You want this unit to power up, without hooking the 2 power wires??? Red is constant power, yellow is switched power. Did you use a wiring harness to hook the radio up or did you hard wire it? I alway recommend a harness. This would make the install easier. If the unit works witht them wired, use it.

sounds like you don't have power going to the red wire. should be a switched power source so it turns off with the key.

there must be a fuse that you missed check under the hood and inside the car for fuse panels and make sure that connections are still hooked up the ones that your husband did.

As long as you have connected the ground(black) try adding one wire at a time to the live(red). If possible try connection each wire one at a time to the power line and then both together. If nothing has blown(fuses) and the unit starts working then you can try by trial & error method the remaining wires. You should be able to figure out which wire is required and if there are any extra wires like cellular phone(mute) and then decide whether to connect them or keep them open.....sodeep

You have wired something wrong. Find a different power wire for your radio. Best to hook a power wire into the fuse box, and have an inline fuse for you radio. And then run a ground wire to your steering column or something.
If it's not that, then you must have pulled a wire off somewhere, and now it's grounding out and blowing your fuse. Have fun. Wiring sucks!

If the dvd player was wired right you wouldnt have that problem, however, you are probably right about the fuse. check fuses under dash.

My thought is that there is a fuse blown. If you put the factory back in and that didn't light up then there is definately a fuse blown. Correct me if I'm wrong but guessing that you didn't cut the harness, by the fact that you could put the factory unit back in, you probaby don't have a problem with wiring. Aslong as you matched up wiring colors with the harnesses the wires should be fine. The next problem should be a fuse. Not all fuses blown in a way that is easy to see. Just replace the "radio" fuse in your fuse panel and give that a shot. If you still have problems get back to me. Good Luck!
