Hey guys I'm new to this forum didn't know where else to turn to for help before i take the car to the shop.. well here's my scenario. My GTO will not start if i let it sit over night or a couple hours when i turn the key all it would do is click once and then click one more time but when The car only start is when i let the battery charger charge the battery for a lil bit of time or i hook up jumper cables to the battery. .. I have changed the battery checked the connections, the grounds, starter and i have had the charging and starting system tested. Im running out of ideas i really dont wanna take it to a GM dealership but if thats what i have to do i have no choice other than to do that if you guys could throw out some ideas or if this has happened to you i would greatly appreciate the help guys.. once again thanks guys hope to hear from you guys soon

The first thing you need to do is get a volt meter and check both battery voltage 12+v, and running voltage 14+v. If you do not have 14+v while the engine is running then you have a charging system issue, such as a problem with your alternator. If your battery wont take a full charge of 12+v then you need a battery. Even new ones can have a bad cell. Not very often, but it happens. After checking your voltage search this forum for starting issues with your results. Hope this helps you out.

Thanks for replying my friend but I have checked it with a volt meter and the battery was maintaining a charge of 12.6 to 12.8 after i got it to start and then when it was running the battery was holding 13.8 to 14.2 volts. Me and my buddy were thinking that there is a minor drain somewhere i remember talking to a GM Tech when i was at work and he was saying some thing about the cars computer draining the battery and the the computer would have to be reflashed but im trying to see what other ppl think before i take it to the shop since it could be some thing i over looked

You guys definitely did the right thing with the volt meter check as the first step.

If your problem is electrical, here is next place I would check. The wiring harness rubs on a metal bracket right behind the glovebox. All you have to do is pop out the glovebox (only one metal clip and a pin--pulls right out) and look up to see if the wires are stripped. I adjusted my passenger's side seat all the way back and laid upside down with a flashlight. This was the night after I bought the car (79k used), and sure enough mine were wearing through. Check out the pictures and more details in this thread:

This is found in the Tech Lounge forum along with a lot of other common problems and simple modifications people have made to maintain the car. Once your car is up and running well again be sure to give this stuff a look. It's golden and could save us all thousands in the long run. Lots of great member input and knowledge on this site.

The car electronic's won't drain the battery overnight. Unless something is taking a poop (like your BCM maybe? BCM harness is another good place to look, as mentioned by this fellow ^^^).

You may also have poor connection at the terminals or grounds, which can cause similar symptoms.

These cars normally will drain the battery after sitting for sometime, but if you are draining overnight you have have more than a minor drain. If you do a search there are quite a few threads that have the exact info you are looking for. Here is a link to a thread with your problem, and a list of things that need to be checked for parasitic loss.

Make sure your ignition snaps when you pull the key out. This removes accessory power.

Mine has been doing this from time to time. I find that if I pull both the positive and negative and put back on it starts just fine.

I have had both the battery and the alternator checked and both are fine.
