Why Won’t My Jeep Compass Start?

There are many reasons why a Jeep Compass might not start. Some are more serious than others, warranting a complete replacement rather than a quick fix. What are some of the most common reasons a Jeep Compass might not start?

Let’s discuss each of these causes to determine what might be causing this error in your vehicle. The more you know about your Jeep Compass, the sooner you can address the faults and get back on the road.

Dead Battery

The most frequent cause of a Jeep Compass failing to start is a dead battery. Most of the time, this fault occurs when the vehicle sits around for a long time without use. The engine doesn’t have enough power to start, resulting in a lack of energy from the engine.

Unless the battery is at the end of its lifespan, you can fix it with a jump-start. If that process does not work, it’s necessary to replace the battery of your Jeep Compass. The battery is necessary if you want to move the car forward.

Alternator Troubles

The alternator is a critical component in a Jeep Compass, providing energy to charge the battery. This issue most often occurs in cars that are more than six years old. The alternator can only last so long, and it will fail if it works for too long. Without the alternator, there is no supply to the battery.

If you determine the alternator is in trouble, it’s necessary to replace it. It will cost much more to fix the alternator. If you know how to work with the car system, you can save money on labor and replace the alternator yourself. If not, take it to a professional and have them complete the job for you. Don’t attempt it if you don’t know what you are doing.

No Fuel

Another common reason is much simpler – there is no fuel in the tank. Your car may have run out without you noticing, especially if you have just been on a long trip. Many forget how low their tank is when parking the vehicle for the night, then come back to an empty car. A leak is rarely the issue.

It’s simple to fix this fault if you notice no gas in your tank. You need to obtain gas, bring it to your vehicle, and refill the tank. Once the fuel settles inside the car, you should be able to start it once again. This fix is the simplest to address.

How Do You Start a Jeep Compass With a Dead Battery?

The best way to start a Jeep Compass with a dead battery is to jump it. To complete this process, you need jumper cables and another car or power source with enough power to bring life back to your vehicle.

You can jump-start the Jeep by:

  • Connecting the red cable to the positive ends of each battery source
  • Placing one end of the negative to the working vehicle
  • Putting the other black end to an unpainted part of the engine
  • Starting the Compass
  • Removing the cables in reverse order

It should work after these steps.

Take care to remove jewelry and keep open flames away from the jumping process. Otherwise, damage could hit you and anyone else nearby.

If you have a manual transmission you could try popping the clutch. Roll the vehicle forward while in neutral and then slam into gear. The momentum should turn the engine over. It doesn’t always work and it’s not the best thing for your transmission.
