No start No dashboard lights and no start?

Hello,

Have you tried to jump start it?

Unless there is a issue with wiring you should get dash light to come on.

When you turn the key does anything happen at all? Sounds like a drained battery so we should load test it but if you try and jump start it and get more action out of it then that would indicate a battery drain issue.

Here are a couple guides that will help with this. Let's start with jump starting it and going from there.

If your 2011 Nissan Sentra is not displaying any dashboard lights and is not starting, it could be indicative of an electrical issue. Here are a few possible causes to consider:

Dead Battery: Check the battery voltage and ensure it has a sufficient charge. If the battery is dead or the connections are loose or corroded, it can prevent the electrical system from receiving power.

Faulty Ignition Switch: The ignition switch is responsible for sending power to various components, including the dashboard lights and the starter. A faulty ignition switch can cause a complete loss of power and prevent the vehicle from starting.

Blown Fuse: A blown fuse in the electrical system can result in a loss of power to the dashboard lights and other vital components. Inspect the fuses and replace any that are blown.

Faulty Starter Motor or Solenoid: If the starter motor or solenoid is not functioning correctly, it can prevent the engine from starting. You may hear a clicking sound when attempting to start the vehicle if this is the case.

Malfunctioning Body Control Module (BCM): The BCM is responsible for controlling various electrical functions in the vehicle. If it malfunctions or fails, it can result in a loss of power and prevent the vehicle from starting.

Let me know little more info and I am sure we will be able to figure this out.

Thank you.
