I’m sorry to hear that your Nissan Sentra is giving you trouble. The most frequent causes of a Nissan Sentra not starting are a bad starter, a bad alternator, or a dead battery.
Your Nissan Sentra won’t start or is having trouble starting for a variety of reasons. Even while the majority of the problems aren’t critical, if your battery entirely dies or your alternator stops functioning altogether, traveling without correcting them could leave you stranded.
The following are the most typical causes of a Nissan Sentra not starting:
- defective starter motor
- inadequate alternator
- Key fob battery failure
- fuel pump malfunction
- worn-out ignition plugs
- Battery deterioration
- an inadequate or dead battery
By measuring the voltage of your battery with a multimeter at home, you can determine if it is the problem. If you measure 12 to 13 volts, your automobile battery is healthy and the problem lies elsewhere. If the voltage reading is less than 12, the problem will probably be resolved by replacing the battery.
