You know how old the battery is?

You tested the voltage across the terminals?
Got 12.6 volts?

  • Anonymous May 30, 2012

    battery is only 4-6 months old, the voltage is 12.13

  • Anonymous May 30, 2012

    Now you have to see if it will take a charge
    At 12.1V it is completely dead
    The alternator may not be working
    or you have some module not timing out

SOURCE: 2003 cts will not start - 101,000 miles

it sounds like your alternator let go, therefore your battery is not charging, you will need to investigate further but the rattling would be explained by the alternator mechanically breaking internally and failing to charge the battery resulting in your present situation

SOURCE: Please help

You sound like you have a computer problem on your car, as all this stuff would not go bad at the same time, unless hit by lightning or you had a major electrical melt down. You can try to disconnect fuses for the different systems you do not need and see if it will start and run, starting with the security system fuses.

After that, I would probably look for a used computer and install it. It is located under the glovebox in the trunk and is pretty easy to change if you are up to it. They are not mounted in there very hard, and the biggest thing would be to find the same computer to verify that this is your problem. I have one for a 95 Eldorado and is probably the same, but I can't be positive on this. You might want to find out from a dealer. Most of the systems dhould be the same, but there could be some differences.

It would be best to take it to a dealer, but they would probably want to order a computer to check it out and charge you for it, whether it fixes it or not.

Like I mentioned, most of them computers are the same, and they do have a chip that can be changed that has the differences in your car programed into it. You could find a computer, change it out, then with the computer out, change the chips and try it again.

This is a pretty big gamble, but for that many things to go wrong at the same time, it would be my guess that is your problem.

go have your battery and alternator tested. Then you can reset your computer by leaving the battery disconnected for 30 minutes. Sounds like you ahve a bad battery, alternator, or voltage regulator. The voltage regulator is inside the alternator.

When stopped at traffic light or just stopped with motor running it has a jerking motion, have just had one of the fuel injectors replaced, it looses power when driving has plenty of power taking off

If you have a check engine light on, pull the code. Jerking while stopped is often a sign of needing a tune up, but it can be other things too. If it's been a while since last tune up, change plugs and wires.

2001 4Runner. Car security went bust first, then the horn stopped working, then the hazard lights. Now, the brakes as well. Any help please?

All except the brakes sound like fuses failing, or wires breaking. A quick check of the fuse box should remedy those.

What do you mean by "the brakes"?

does the pedal go to the floor without stopping the truck?
do the brake lights not come on?
is the brake indicator on the dash on?

need a little more to go on

You should have disconnected the battery and fully charged it before starting the car.
The low voltage may have damaged some of the electronic components in the alarm system.
Charge the battery fully, then reconnect it and see if that helps.

My car horn randomly goes off while car is off?

The horn works by earthing, normally done by you pressing switch, if the horns wire or the internally creates a contact to earth(chassis) your horn will sound. Take your switch apart on you steering wheel & give it a clean.
Hope this helps, if not, remove wire at horn end, leaves you with no horn but peaceful nights.
Have a nice day.

Engine light comes on intermittently after car shimmies

Even though the light went out, there should still be a code stored in the computor.Without the code, or testing this and that to pin point the problem it's hard to say. I don't want to tell you replace this or that without knowing. It would be a waste of money for things you don't need. good luck.

My automatic focus sometimes will not go into gear properly

This may be caused by fluid starvation from a plugged trans filter, also a shift solenoid inside the trans may be sticking, I would recommend u change the trans fluid and filter (required at 60,000 miles), also go to a Kragen auto or any chain parts store like it and ask to have a code test run on the powertrain control module , it is free.
