Volvo S80 car will not crank despite having a battery charger on Volvo S80

Some Volvo S80 owners report experiencing issues with their vehicles not cranking even after using a battery charger, which can be attributed to several potential problems. A weak battery is commonly cited as a reason, where dashboard lights may illuminate, yet the battery lacks the strength to crank the engine. Additionally, if the battery is functioning properly, a faulty starter motor may prevent the car from turning over. Owners also note that blown fuses connecting the battery cable to the starter can lead to this issue, as well as problems with the starter relay, where the Central Electronic Module may fail to send a ground signal. Furthermore, some owners encounter immobilizer system messages, indicating that the immobilizer may need to be checked and reset. Lastly, diagnostic trouble codes related to components like the camshaft position sensor may surface, signaling further issues that affect the starting process. It is advisable for owners facing these challenges to seek assistance from a professional mechanic or a Volvo specialist for accurate diagnosis and repairs.
