it indicates that the alternator is not functioning sufficiently to keep the battery charged.
bad ignition, bad battery, bad starter, need more info in the question
The starter motor requires a great deal more of electrical current than do ordinary light bulbs. The lights working is not always an accurate measure of the battery condition.
My 2002 chevy impala security lock but i can jumpstart it and it start but after a few hours it dose it again how can i fix it
Not without "hotwiring" it
try turning key on (don't start) then pump gas to floor 6 times, light should flash then go out (works with many chevy's, but not sure about Impala)
Just like you jump start any other car. Connect positive cable to positive post of battery and connect negative to any metal part of the engine or frame.
your battery may be dead or try unhooking your battery for 1 hour then hook back up and try again
An alternator keeps the battery charged in a vehicle. In a 2006 Chevrolet Impala when the alternator fails the battery will keep dying and no power will be available when attempting to start the car.
Turn on the ignition but do not start the engine. Depress the accelerator to the floor 3 times within 5 seconds. The oil light should blink and then go out.jd
Your 2003 Impala might not start up because the battery is dead or the starter is broken or damaged. It might also not start because the fuel tank is empty or the fuel pump is broken.
get a circuit tester and start looking with the key on
If a 2001 Chevy Impala will not start after replacing a thermostat, perhaps it is possible that a sensor was bumped unknowingly. Check all of the sensors that might have been touched during the changing of the thermostat to see that they are all still plugged in.
