2G Several electrical problems

your ecu has a KAMP.. that is keep alive memory power, might be worded different, and so does your radio. it will spark when you connect them. if your battery doesnt go dead with sitting for a week then i would not worry about it.. usually you will get the multimeter and put it between the ground on battery and the ground terminal(with possitive still connected and negative not) and measure DC AMPS. that will tell you your current battery draw..

also when you turn your key on your check engine light will come on for a number of different things. because your car isnt running your ecu doesnt have all the inputs it needs so it is on.. when you start it they go away because they are "soft" faults.. which means they clear out when they are fine.(i.e. no oil pressure, battery light, etc)

if you have that o2 unplugged that would be a hard fault and the light should stay on even when car is running. but it might not. i would think so being your car is OBDII. do you have an aftermarket radio? if so maybe someone wired it into the wrong ground or power and it is taking it from the wrong place..

alot of things when not turned on will act as a "ground". so someone probing for ground wire might use the wire for the dome lights because the factory radio is connected to the dimmer switch for the interior lights... just a thought.if they didnt use a plug and play connector
 
Sorry about the multiple threads, I thought it didnt post so i made another one. This was helpful alot. Its an aftermarket radio and i took it out, the wires are all hacked so today i will rewire all of it the right way and see what happens there. Yeah, the use of the multimeter confuses me alot because there are so many diff things you can test on it and i dont know what numbers i am looking for like resistence or voltage and if it should be high or not, but the other thread you sent me i have bookmarked so i will read it over and over. thanks guys
 
Ok well then i must not have a short. The aftermarket radio wires were all hacked up in the first place so i will start there first by rewiring it the right way. And sorry if you guys see another thread that is the same as this by me, I accidently made two. And for the multimeter part, that helped a little, I am just trying to figure out what numbers i am looking for and what i should test first, battery, alternator, and etc
 
What are you looking for exactly? I think you need to restate your problem so us thread dwellers can give you better advice. Are you still concerned about the interior lights not coming on, door ajar, etc or is it another issue?

Side note on the rear O2 sensor, mine was unplugged for the longest time, and I'd only occasionally get a CEL for it. On and off it went. Meh.
 
Yes the interior lights like you said and the door ajar noise along with no power to the ecu diagnostic port and radio dont work. I rewired the radio wires the correct way but still no fix. I been reading all these other threads that you guys sent me but i still am confused, electrical is not my forte.
 
CD player loses power
no dome light
no door ajar ding
No security light
CEL quit lighting up
Now, when you open the door the CD player shuts off

Since the last thing in the first post was the CD player shust off when you open the door, lets start with the Dome Light circuit. Start by removing the bulb(s) from the Dome Light. Now, turn on the radio and open the door. Does the radio stay on? if yes continue, that tells us there is at least a partial short in the dome light circuit. If the radio turns off still, let's move to the switches in the door jams.
Close both doors with the radio on, and open one at a time. Does the radio turn off when you open either door, or just one or the other? If it is just one door, it is probably the door jamb switch shorted to ground. This will cause no voltage to get to the dome light, and can take voltage away from other components. To verify this, you will probably need to remove your kick panel and have some very small hands. You may also want to remove the door panel and take a look at the wiring inside the door. Make sure the insulation is not broken or rubbed through. Shorts can be a very tricky thing to trace out and can make even the most experience troubleshooter cuss and throw tools.

Let's start here, and move on after we eliminate these issues.
 
I would follow this but my cd player doesnt turn anymore. It hasnt for a while so i just leave it un hooked. Is there another way other than using the radio to help me find this problem. I thank you guys so much for helping me this far.
 
I will have to try to hunt down a schematic for the 2g... Like I said, without one, it is nearly impossible to guide you without some kind of test like the radio. The radio turns off when you open the door kinda points me to a door switch, but it could be something else. I will start searching for a schematic and get back with you.
 
Yeah I understand, I will try my best to try and find this problem.

I was going to ask, do you think it might work if I hook up the radio and do what you say to do, would it turn the radio on if im pulllin out bulbs and what not?
 
i lost power to my diagnostic port and interior power once. it ended up being my fuse in the engine bay. it was one of the ones that is bolted in on the top left side. 100amp fusible link..
 
Easiest thing to do is disconnect power 12v Ign and ground from the radio. Run your own 12v and Ign to the ignition switch under the steering column. Ground your own source to the chassey. Cap off the wires not being used behind the radio. What it sounds like to me is that you have an illumination wire hooked up to your radio. When you open the door it changes polarity and is shorting the radio out. You may have cuased some damage to wiring or fusebox and possably ecu. First I would wire the stereo like I said and see if that fixes the radio issue and go from there.
 
ok, after pouring over an electrical section of a service manual I found online, I found that all of those things are connected to the factory security system. Perhaps it has an internal short that is pulling voltage away from those items.

They are also all connected to dedicated fuse 11 and fusible link 2. We can assume those to be good, because you get power off and on. I have seen some fuses do wierd crap though.

Then of coarse, there is the ETACS system. I don't know if you have that on your car or not, but it controls all of those Items from what I can tell. I would start by unplugging the security system and see if your dome light works again. then go from there.
 
The service manual didn't show the location for the security system...

this is the link to the manual... the diagram is in about 100 pages, and kind of hard to follow. There is a section that shows where all the components are, but I never saw the security system. Maybe it is integrated to the ETACS computer. Someone else may have more info on that for you.
 
Ok i been busy with school stuff and My car is in the shop getting a new window so when i get it back later today and i will try doing with daddyo says and i will see what the outcome is, wish me luck

i will also do what palmetto said to do with disconnecting the dome light.
 
Now my dash lights and back lights dont even turn on.

nvm it ended up being on of my 10a fuses that was blown from trying to rewire my radio. Brace with me people, I am by far the worst with this kinda shit
 
Now, I got my dash lights and back lights to work. I used to have lights that worked on my gauges that are in my pod and in the beginning of all this is when they sometimes would come on and turn off. I look under the steering column and there was a blue wire that was connected to all the gauges in the pod and it must have been connected to something and now its not. Could someone please tell me what its suppose to be connected to?

scratch that. Found out it was a power wire and it was hooked up to a power wire on the dimmer switch. Is that where its suppose to be hooked up? I know this doesnt have anything to do with my thread but no one has got back to me, If i have to take my car to a shop, where whould i take it and what do i have to do to make my car acceptable to be looked/worked on?
