I left the radio on now my car wont start, try to jump it ,it started but it wont go fast

reversing cables blows out electronics.
only hope is fuse blow.
beyond that expensive repair.
learn use jumper cables properly or go broke fast.

You got a jump and it ran fine? It's your battery. The lights and radio are much easier for a battery to handle than spinning a car engine. Again, if all you needed was a jump, you have a bad battery.

OLder cars YEs you can jump it without a battery. But in newer cars that use computers and advanced Eltronic ignition/timing/ful injection you have to have power to the cars computer. without a good battery the car will not run.---------------------------------------------------------------------------------

Hi Chris, Check the battery and terminals. Try a jump start and if that works replace the battery. Regards John

the symtoms you describe sounds like a battery fault. but if you have had the battery properley tested and is good then you either have something discharging the battery intermittantly ie. trunk light staying on or a high resistance in the main battery leads or earth connections

need to check your starter before going to check the sensor.

charge battery fully do not jump it turn key on for 30 sec than offf ,car should start

Check the connections to the starter for corrosion gets everywhere

Hi
Try to jump start the car.
Put the jump leads on and leave it for 10 mins
that will charge the battery up
then try and start.
Also check the starter motor.

flat battery. jump start it
