My 2003 Mercedes Benz C230 Won#039;t Start


1. Add an additional gallon of fuel to your C230's tank. Turn the key in the ignition to the 'START' position, but not all the way on. Turn the key on and off several times while pumping the gas pedal. This helps to engage the fuel pump if it has been empty.
2. Plug in an onboard diagnostic tool (OBD) to your Mercedes C230. The outlet for the OBD is under the steering wheel. Turn it on and then turn on your vehicle. Allow the OBD to read your car. It will show the codes for problems within the engine. Consult your dealership to translate the codes. The incorrect coding that caused the recall can lead to the check engine light not coming on when it should. The OBD tool will show any items that would have caused the check engine light to come on.
3. Turn the key in the ignition, but do not start the car. Check dashboard lights to see if they are dim or do not come on. Dim lights indicate a drained battery. No lights indicate a dead one. Recharge or replace as necessary.
4. Turn key to start the car. A clicking noise can indicate the starter. A thumping noise is a sign that several parts are malfunctioning, including the fuel line or its components such as the pump or filter. If there is no noise and the battery has been replaced, there may be a problem with the ignition.
