Symptoms of Jeep Grand Cherokee Intermittent Starting Problems
If you’re experiencing intermittent starting problems with your Jeep Grand Cherokee, it can be frustrating and concerning.

Not being able to start your vehicle can leave you stranded and unable to go about your day.
However, identifying the symptoms of this issue can help you diagnose and fix the problem quickly.
Below are the common symptoms of Jeep Grand Cherokee intermittent starting problems.
Clicking or Grinding Noise
This noise indicates that the starter motor is not receiving enough power to start the engine.
If you hear this noise, your battery is likely low or failing, or there may be a problem with your starter motor or alternator.
The Engine Cranks, but Won’t Start
This means that the starter motor is turning the engine over, but the engine is not starting.
This can be caused by a variety of issues, including a bad fuel pump, a faulty ignition switch, or a clogged fuel filter.
Intermittent Starting
This means that sometimes your vehicle starts with no issues, while other times it won’t start at all.
This can be caused by a faulty ignition switch, a bad starter motor, or a problem with the fuel system.
Slow Cranking
If your Jeep Grand Cherokee is cranking slowly when you turn the key, this is another symptom of starting problems.
This can be caused by a weak or failing battery, a faulty starter motor, or a problem with the alternator.
Dashboard Lights Flicker
Finally, if the dashboard lights flicker or dim when you turn the key, this can be a sign of the Jeep Grand Cherokee’s intermittent starting problems.
This indicates that there is a problem with the electrical system, which can be caused by a faulty battery, alternator, or starter motor.
Common Causes of Intermittent Starting Problems in Jeep Grand Cherokees

Here are the common causes of intermittent starting problems in Jeep Grand Cherokees:
Weak or Failing Battery
If your battery is low or failing, it won’t be able to provide enough power to start the engine.
Faulty Starter Motor
The starter motor is responsible for turning the engine over when you turn the key. If it’s faulty or failing, it won’t be able to start the engine consistently.
Bad Ignition Switch
The ignition switch is what sends power to the starter motor when you turn the key. If it’s faulty or failing, it can cause intermittent starting problems.
Fuel System Issues
Problems with the fuel system, such as a bad fuel pump, clogged fuel filter, or faulty fuel injectors, can cause intermittent starting problems.
Electrical Issues
Electrical problems, such as faulty alternator or wiring issues, can cause intermittent starting problems by preventing the battery from charging properly or delivering power to the starter motor.
Faulty Fuel Pressure Regulator
The fuel pressure regulator is responsible for maintaining the correct fuel pressure in the fuel system.
If it’s faulty, it can cause intermittent starting problems by not delivering enough fuel to the engine.
Clogged Air Filter
A clogged air filter can restrict the flow of air to the engine, which can cause starting problems, particularly in colder weather.
Troubleshooting Tips for Jeep Grand Cherokee Intermittent Starting Problems

Below are some troubleshooting tips for Jeep Grand Cherokee’s intermittent starting problems:
Check the Battery
Start by checking the battery. If it’s weak or failing, it may not be able to provide enough power to start the engine.
Use a voltmeter to check the voltage of the battery. If it’s below 12 volts, it may need to be replaced.
Check the Starter Motor
If the battery is fine, the next step is to check the starter motor. A faulty starter motor can cause intermittent starting problems.
Use a multimeter to test the resistance of the starter motor. If the resistance is outside of the manufacturer’s specifications, it may need to be replaced.
Check the Ignition Switch
If the battery and starter motor is fine, the next step is to check the ignition switch. A faulty ignition switch can prevent power from reaching the starter motor.
Use a multimeter to test the continuity of the ignition switch. If it’s not working properly, it may need to be replaced.
Check the Fuel System
If the battery, starter motor, and ignition switch are fine, the next step is to check the fuel system.
Problems with the fuel system, such as a clogged fuel filter or a faulty fuel pump, can cause intermittent starting problems.
Check the fuel pressure and fuel filter for any signs of damage or clogs.
Check the Electrical System
If everything else is fine, the problem may be with the electrical system. Check the alternator, wiring, and fuses for any signs of damage or wear.
Use a multimeter to test the voltage of the alternator. If it’s not charging the battery properly, it may need to be replaced.
Check the Air Filter
A clogged air filter can restrict the flow of air to the engine, which can cause starting problems. Check the air filter for any signs of dirt or debris. If it’s dirty, replace it.
