It is possible that your car battery has a trickle draining with a leak in the electrical electronic system.Due to this the battery is drained of when the car is off.You will need to check for the drain current with an ammeter in series to the battery and to individual circuits. you can find the circuit with the high drain., Now check also the charging circuit , the alternator and rectifier/regulator.
The car stopped in traffic maybe due to poor firing or tuning which must be checked with an overall check on ignition and fuel tuning.

Get your alternator checked. You could also have a grounded wire or an interior light is staying on. Check the lights in your sunvisor mirrors, sometimes they fall just a little and allows the light to come on.

Bought new battery. morning vuka don't want to start. mornings I had to jump start it 0km still refuse to start on its own


Probably something draining the battery overnight. Interior light left on? The regulator in the alternator could be bad and keeping the ignition energized draining the battery. If your jump start it drive to work get off work and it starts after 8-9 hrs you have a system voltage leak some where. If nothing is left on overnight have the voltage regulator tested in the alternator.

My 2000 cadillac deville wont start. Battery and alternator good. Trunk or gas door will not open either until I start it. I jump start it and its fine all day until the next morning.


If you can jump start it, then it is most likely the battery. Unless you have had the battery Load Tested, a simple voltage check is not enough to ensure there are enough amps there to start the car, especially on cold mornings. Since you can warm start it and it seems to do well all day, my bet would be a weak or dead cell in the battery.

I have a 1998 hyundai coupe 1599cc the engine cuts out when idling and i have to jump start it or wait for about half an hour before it will start again


This sounds like a battery or alternator problem.

Lets start with the battery, just because the car starts in the morning does not mean the battery is good, A bad battery will start the car and as car is running and drawing power out of the battery the battery which is getting charged back up from the alternator but if battery is bad and not accepting the charge this will do a few things.
First it will cause damage to the alternator because , the alternator will try to charge the battery with no result and so it keeps charging at high rates and heats up and causes damage to itself , the next thing is battery loses voltage slowly until it does not have enough voltage to keep engine going , inturn engine stalls out,
I would start by first having the battery tested by a shop with a battery tester, the next thing is the alternator , have that tested.

Your problem will be a bad alternator or battery. good day.

Hi my car wont start,after i get a jump it will run that hold day then the next morning nothing will come on no lights anything


your charging system is working okay or you would have to have it jumped more than once a day.you have a bad battery that needs replacing as running it during the day the charging system keeps the battery charged up enough to work.you could have a drain on the battery from something in the car that is not shutting down that you will have to have checked out.or sitting over night the battery runs down to the point that it needs to be jumped started if its an old battery(over5-6years).

GOT HOME FROM WORK YESTERDAY AND CAR DROVE FINE. GOT IN THIS MORNING AND CAR ONLY TURNS OVER , BUT WILL NOT START.ANY IDEAS?


Sounds like the battery might not have enough power to start engine. Even though, the radio might play and the lights may come on does not mean there is enough power to start engine. Try charging or jump starting it. These are simple tests to see if it is the battery. If the car starts after charging or jump starting, it was most likely the battery. Just let the car run for ten or so minutes before shutting off to charge the battery. Hope this helps

Had to jump start my battery this morning. Now


It's kind of something telling you that your battery shot. The battery isn't pushing out enough amperage to have things properly function. Replace the battery if the car will not start again after running for about 2 minutes
