A few days ago I was able to tun the key and everything would light up now when I do so nothing happens, I have checked the battery and all the fuses and they are all good. I thought it may be the starter switch so I checked that as well and everything other then the black and red wire has 12 volts. Any ideas what might be causing this?

 

Power to main fuse panel under hood? Blown 80 amp main fuse?

 

What does light up mean? Have you checked the battery terminals, or battery itself? If you jumpered the car do you get the very same results.

 

This is going to sound insane but...

Last night when leaving work, everything on my car worked but the starter would NOT spin. My co-workers helped push start it. I got home and the starter still wouldn't spin. Thought I needed a new starter.

I sat on my porch for about 30 minutes and had a cig, after work, drank some beer and my beer hat told me something!

"It isn't the starter , it's the positive battery terminal!"

So, I popped the hood and poured some beer for my homies on my battery terminal. Started right up.

Check your battery terminals.

 

The fuse is good and has power going though it. As for the terminals they are a few weeks old. By light up I mean when I turn the key nothing comes on not even the door lights or the key in chime. I used a multi meter and found that I have power coming from the battery though the main fuse block and into the fuse block under the dash. I also have it coming into the ignition switch but nothing comes on when it's turned.

 

Do the wipers or turn signals work w/key to on. And the BTN fuse powers some of the items you mention. It's in the engine fuse box and it powers a White/Red wire and should have constant power so check this fuse/wire. This fuse powers the hazards and stop lights as well as interior lights.

 

Nope nothing comes on.

 

You say is has 12v but I don't know if you mean that is the colloquial "full charge" or in the technical "it only has 12v". Traditional batteries are made up of 6 lead acid cells of 2.1v nominal each for 12.6v.

12v resting voltage at the battery is low.
Even a battery with the proper 12.6v resting voltage could be dead and give these symptoms.

If the battery has 12.6v resting voltage but the rest of your system has 12v resting voltage then there is a big problems somewhere in your wiring, likely the main power or ground wiring.

If you haven't already, I'd get the battery tested and/or swap in a known good battery with similar ca/cca rating.

 

The plug at the ignition switch which receives voltage from the main fuse would house two wires. The Black wire would have the constant voltage which is the wire you must have checked. Correct? The other wire in the plug would be Black/White which powers the IG1 fuses in the interior fuse box and this B/W wire would have voltage w/key to on. Does it. And are you sure you didn't reverse the polarity on the battery by placing the battery terminals on reverse wise? If you are certain the battery is connected properly then make sure the ground wire is grounded to the body properly. If all this checks out and the B/W wire at the ignition switch does not have voltage w/key to on then the ignition switch could be faulty but the interior lights are independent of the switch so that is a bit of a head scratcher.

The fuse which lights the interior lights is the illumination fuse so check the fuse to see if it is receiving 12 volts or not.

 

I had some time today to go out and look at the car. When I pulled the battery in I heard beeping from in the car do to me leaving the key in the acc position. Having a hunch I turned the car off and plugged in the aftermarket radio and sure enough it wouldn't turn back on. I turned it off and unplugged it and the car came back on. Any ideas what could cause this?

 

Your battery likely needs recharging for starters. And your ignition switch might be acting up which is why it was stated how to check it in a previous post.

 

Well I went out and checked the switch like you stated. The first time I checked it with the key out I didn't have any power going to the acc fuse and then I switched the key on and suddenly had power and again I checked the acc fuse and I was getting 12.5 volts. again I tried to plug the radio in and it died. This time I checked the acc fuse and with the key out I am still getting 12.5 volts.

 

The ignition switch has a series of plugs connected to it. One plug has a Blue wire and a Black/Red wire. W/key to ACC the Blue wire should have power (B/R wire has voltage w/key to on). If the Blue wire has voltage w/key to the off position or key not in the ignition then that points to a problematic ignition switch.

 

i think you need to fix your battery terminals.
