Mercedes-Benz C320 no crank no start issue after new battery installation on Mercedes-Benz C320

Some Mercedes-Benz C320 owners report experiencing a no crank, no start issue after installing a new battery, which may indicate a ground problem that requires checking the throttle body and measuring all wires for ground connection issues. Additionally, a common cause for this problem could be a failed crankshaft position sensor, which is relatively easy and inexpensive to replace. Owners also note that if the lights and radio activate but the engine does not start, it might suggest the battery has very low power. Utilizing diagnostic tools, such as an Ancel diagnostics tool, can aid in accessing modules and diagnosing the root cause of the issue. Furthermore, some owners find that problems with the fuel system, including fuel pressure, fuel pump, or fuel filter issues, can contribute to the no start condition. If these troubleshooting steps do not resolve the problem, seeking assistance from a professional mechanic or dealership is advisable for a thorough diagnosis and repair.
