Why Did You Have To Bump Start?
3 possible reasons spring to mind,
The battery is dead,
The alternator is faulty,
the starter motor is siezed.
How Do I know Which one It Is?
The battery is located in the passenger footwell under the foam block, test the battery with a multimeter to determine the voltage. It should show over 12 volts.
Start the car up and place the multimeter on the battery terminals again, if the alternator is working correctly you should be able to read a voltage of about 14.2 volts or higher.
If the starter motor is siezed, the engine won't turn over dispite the battery being fine.
Once the car has been push started it should drive normally and the battery light shouldn't be illuminated at any time.
