I installed an after market radio in my vehicle and one day it just quit working. I put the factory radio back in and nothing no power. It doesn't ask for codes or anything. I have looked at all the fuses and replaced the radio fuse but I still cant get any power or anything from the radio.

Hello,

Here's the power feed wiring colors for the radio, let me know if these match what you have at the back of your radio, just to make sure we've got the right ones, you can check power on these wires coming from the ignition switch with a test light. Also check that the black ground wire didn't come loose.

Do you have any of these wire colors at the back of the head unit? White, purple, and black. These are the wires that power up the head unit. Can you send a picture of those plugs, make sure you have power at the radio fuse too? you can check that with a test light attached to battery negative.
