Car will not turn over have power when turn the key nothing?

If your 2020 Mitsubishi Eclipse is not turning over when you turn the key and you have power, there are a few possible causes for this issue:

Weak or dead battery: Even if you have power to some electrical components, the battery may not have enough power to crank the engine. Check the battery voltage using a multimeter or have it tested to ensure it has sufficient charge. If the battery is weak or dead, you may need to recharge or replace it.

Faulty starter motor: The starter motor is responsible for cranking the engine. If the starter motor is faulty or worn out, it may not engage and turn the engine over. A clicking noise or a single click when you turn the key could indicate a problem with the starter motor.

Ignition switch or ignition system issue: A malfunctioning ignition switch or a problem with the ignition system can prevent the engine from starting. Faulty ignition switch contacts or a faulty ignition coil are possible culprits.

Fuel delivery problem: If there is a problem with the fuel delivery system, such as a clogged fuel filter or a failing fuel pump, the engine may not receive enough fuel to start.

Engine immobilizer system: The engine immobilizer system is designed to prevent unauthorized starting of the vehicle. If there is an issue with the immobilizer system, it may prevent the engine from turning over.
