With a defective starter solenoid, the engine won’t crank or start. You also aren’t going to hear a clicking noise if this part has failed. 

3. Poor Transmission Range Selector Contact

Within the automatic transmission shifter, there’s a range selector. This part can also be called the neutral safety switch. It could be defective in electrical contact. This can make it difficult for the engine know if it is Park or Neutral.

Thankfully, this problem can be simple to remedy if the problem isn’t beyond hope. Place your foot on the brake, and shift the lever into neutral. Start the engine once more. If it doesn’t work, put it back in Park and try once more. To reestablish the electrical contact, you may need to shift the shifter.

4. Defective Wiring

Many wires run from the switch and the starter. They all need to be in good condition to allow the car to continue to function. It can lead to major starting problems if the wiring is damaged or disengaged.

The car may also stop if the wires connecting the starter solenoid to the ignition switch become disconnected during driving. You must inspect the condition and connection of every electrical wire to diagnose the problem. 

It is also a good idea to check the battery twice. Jump-start your car if it doesn't have enough power.

5. Seized Engine
