Question about 2004 Pontiac Bonneville

5 Answers

Will a weak battery cause my 2004 pontiac bonneville to just shut down while driving down the road?

My wife was just driving down the road and the car started slowing down and just shut off.She waited for about a half hour,it started and ran for about five minutes and shut off again.The battery is only showing about 8-9 volts.

Yes it will (shut the car down)... and if your diode bridge is the PROBLEM... that means you are running AC current into your DC BATTERY...

Things will DEFINITLY not work that way.

Two recovery steps...

-The battery may just be seriously annoyed... Get it charged.
If it takes a charge...

-Pull the Alternator and get it to your AUTOZONE... recommended for their online documents wiring schematics, trouble shooting guides... and specialty tool loaning program...

If they won't test it... find a shop that will... FREE.
Fix it.. replace it... whatever!

Put it back and make sure the battery terminals are all clean & happy... Get some of those cute little red/green No-Oxidation rings and put them on your car (to keep evil spirits away).

Just not at amazon or Costco unless you have a BIG fleet of cars.

Be happy... Drive carefully.

Nota bene:
Two quickest/most common ways smoke your diodes...
Jump starting another vehicle... or not disconnecting your negative battery lead before putting a SERIOUS BATTERY CHARGER on the car.

Napaonline says the same stuff... use whoever you TRUST...!!
(but autozone does have REALLY nice ON-LINE manuals, schematics... etc.

The battery could be the problem but if it was so bad that the engine shut down, I suspect that there is insufficient current going into the battery and electronics system to run everything
The procedure here is to have a load test done on the battery to check for bad cell/s
The next check is the out put of the alternator and the condition and tension of the drive belt
The electronics work like this
The battery is a storage receptacle for the current required to start and run the engine
The alternator is there to provide extra current over and above that which the battery can supply
If the extra is not forth coming then the extras have to come out of the battery which means that over a period of time the battery voltage falls below that which is required to run the electronics so important items such as ECM performance , spark voltage , fuel pump operation etc all come to a stop
Batteries have an ability to recover to a point to start an engine on a once only basis but any extra power is used by the systems and so it will again fail
Have the alternator bench tested for correct voltage (14.5 -14.8 volts dc) and the regulator is operational up to the rated output in amps of the alternator
Check for bad ground wires, dirty black battery terminals, loose terminals, corroded wires around the battery

2004 pontiac bonneville ran for about 5 minutes then shut off. i scanned the computer and it showed a p0230 code.fuel pump primary circuit misfunction.now it wont start at all.battery alittle weak.


check that the pins in the relay socket and the PCM connector are good and make contact youshouldsee12v at pcm... PCM is last resort. Check the fuel relay first for melting or burnt smell.

While driving the car will shut down along with all gauges. after it sets a while it will then start


DO NOT DRIVE YOUR VEHICLE IN THAT CONDITION, IT IS A HAZARD TO YOU AND OTHER ROAD USERS.
If everything shuts down you have amajor issue. The car should be inspected by a GOOD auto electrician...not a mechanic. Describe the symptoms to him.

I react badly when I read about this particular problem, we had a car that once did the same thing while we were on the road, the wife and girls were in the back. Could have lost control and killed us all. Please do not drive it if it does it again. I had that car scrapped straight after

GoodLuck

Engine shut down while driving


2 different issues, Engine shutting off usually with your car is the ignition module under the coils, Windows usually is a broken wire in between the door and the body jam, inside the rubber tube. Might be suprised to find a couple more wires broken

My car stoped while driving down the road. Jump started it but it died again while trying to get home.


Check the alternator to see if it's charging the battery. If the battery is approaching 3 years old then replace the battery.

hi,
i actually used to have a 1995 pontiac grand am that did the same thing....only difference was i didn't have to restart the car....usually what i would do was drop the car in neutral and gas the car and i'd notice my temp gauge go down and my heater gave heat.....chances are it's a sticky termostat. Hopefully that helped.
