My Mercedes E320 Won't Start: Troubleshoot
- 1). Insert your key into the E320's ignition and turn it. Listen for a "clicking" noise. If you hear the clicking noise, you will need to have the car towed to a garage to have the alternator replaced.
- 2). Look at the fuel gauge while the key is in the ignition. Add gas to the car if needed and then try to start the E320.
- 3). Open the E320's trunk and locate the battery. Make sure that the battery terminals are connected to the battery properly. You can tell this by the "+" and "-" signs on the terminals and the connecting wires.
- 4). Connect jumper wires to the "+" and "-" terminals on your battery and then connect the other end of the jumper wires to a different car battery. Start the other car with the wires connected and then try to start your car.
- 5). Leave the E320 running for about 15 minutes to allow the battery to charge. Turn the E320 off and wait for a couple of minutes. Start the E320 again. If the car will not start, you need to replace the battery.
