A Little Help Please
Ok so my problem is that I disconnected the battery to clear a CEL, I'll describe why I had that in a second, and now my car won't start. I turn the key and the dash lights came on at first but dimmed and now don't light at all. When I push the start button nothing happens, no clicking nothing. The lights don't turn on either. However we did push start it and I was able to drive it home no problem. I let it run for about 20min or so. So there should have been some built up charge but I tried to start it right after I shut it off and nothing again, not even dash lights.
What I've tried.
-Reseting the ECU again
-Checked the fuses UTH and Inside that I felt would pertain to this
-The battery seems to have power. The lights on my voltage stabalizer are blinking indicating good power.
The reason I had a CEL is I was doing some exhaust work and had the O2 sensor out. Well about that point I noticed that it wasn't on the lift right so we brought it down and I had to start it and move it. So running car with no O2 senso = CEL.
Any help will be greatly appreciated. I really hope I didn't fry my ECU. Oh and the battery is less than a year old.

First, put a voltmeter on your battery terminals and see what it says. A good battery should read at least 12.5V resting. If the battery is good, I'm going to guess that your voltage stabilizer kit is a piece of crap and is interfering with the power deliver from your battery.

OK, I'll go ahead and check the voltage.
As far as the voltage stabalizer I've had that on my car almost as long as the battery, and I've reset the ecu since then and never had a problem. But I'll disconnect that next if the volts are good and see what happens.
Thanks xviper.

I think Vipers point is in general, they're crap. Useless weight, like a hypergrounding system. Since the battery was good before you disconnected and it's not working now after, I doubt it's the battery. It's far more likely that somethings wrong with how you hooked it up so, it's not charging.
Get the engine running and then read the volts at the battery. If should be 14 or so. That being said, if it's the original battery it's on borrowed time anyway. I'd replace it as a first trouble-shooting step.

Ok so I just tested the battery at Advance and it came back dead. It was <1.0v. Its an optima yellow top thats about 10 months old. So I'm going to take it to sears and try and get my money back. Its still under warranty.

Yeah, unfortunately I didn't find that out until after I bought it. I just got back from sears though and they gave me a full refund. Now I just need to decide which battery I'm going to get.
Thanks for the advice.

I wanted to get a light weight battery when I bought the optima 10 mo ago but I needed it quick because my car died like this time. Well now I'm going to get what I want and suck up some down time. I read many of the posts on batteries so I got to read your opinion on batteries, but I decied to go with an Odyssey PC680T. It was about half the price of the optima I just returned so I used some of the left overs to have it shipped 2 day air.
You used to run a light weight Hawker right? What did you think about it?
