This article is also intended to give you useful guidance to assist with the investigation and is created under the premise that you are seeking a way to fix the issue.

Causes Of Jeep Compass Not Starting But Has Power

Jeep Compass Won't Start But Has Power

Imagine turning the key and hopping inside your Jeep does nothing. Your day can be thrown off if your Jeep Compass won’t start while you attempt to get somewhere. When a car doesn’t start, it can be incredibly annoying.

Even though having a Jeep not starting but has power is annoying purely by itself, the fact that you don’t know what’s wrong with it only makes things worse.

We’d speed up the diagnosing procedure by providing you with the most common frequent causes for a Jeep Compass won’t start, so you wouldn’t have to sit there frustrated and perplexed.

A Dead Battery

Bad batteries are the most frequent reason a Jeep Compass won’t start. The battery health in the Jeep could drain, delivering little to no starting energy to get the vehicle started.

Long-term abandonment and inactivity of a vehicle slowly drain the batteries. The battery’s discharging cannot be monitored by the vehicle’s generator.

If your Jeep Compass has remained idle for a time, the battery may need more power to fire up the motor. You may either jump-start your automobile or swap the battery to repair this.

Furthermore, if your battery is older than three years, it might be necessary to replace it as it isn’t retaining a charge.

Poor Battery Connection

Your Jeep Compass’s battery might be in fine shape, but a poor connection, a damaged cable, or damage to the electrical connections could prevent power from passing.

A poorly connected battery is a typical electrical issue, particularly if the connected battery power is older than two years old.

When battery acid meets with metal connections, corrosion takes place, which can cause a loss of connection and a reduction in the current that flows.

You might only get clicking noises from the solenoid when you attempt to turn the engine if you don’t have enough flow of current to push it.

You must look at the electrical connections to determine if the Jeep Compass not starting but has filthy terminals of the battery, causing power issues.

Examine the connections for any damage by lifting the covers. You might only need to wipe the batteries if you find white or silvery-green deposits but no additional fractures or damage.

If that’s not the case, you are advised to have a battery replacement.

Bad Ground Connection

A bad ground connection is often known as the threshold voltage of the battery being linked to the frame or structure of the Jeep Compass.

Additionally, the vehicle needs a grounding connection to operate; however, due to the vehicle’s mounting, the alternating energy cannot pass between the motor and the chassis.

The connection between the motor and the frame is made using a grounding belt or cable.

You will experience a variety of power failures, including cracking sounds, and a Jeep Compass won’t turn over if the ground connection of your Jeep Compass becomes faulty due to wear and tear.

The vehicle’s grounding connection is necessary for the car engine and its motor to operate effectively.

The starter engine’s large voltage need may prevent it from turning the vehicle over when the grounding is poor, but the starter motor may still function and generate clicking sounds.

A resistivity examination between the battery’s negative electrode and the motor will allow you to evaluate Compass’s grounding connection’s reliability.

For any additional indications of mechanical damage, check the grounding wire connections.

Faulty Alternator

You might have a damaged or bad alternator if your 2015 Jeep Compass won’t start but has power. As well as activating the engine, the alternator charges the battery.

The battery will only have sufficient capacity to start the vehicle if it operates properly.

As a result, even if you switch out the batteries because you believe the battery is to blame for the vehicle’s inability to start, the cell will eventually run out, and the engine will not start.

The alternator must be changed to resolve this issue. A qualified mechanic ought to handle this task.

Rarely do alternators malfunction. Newer vehicles, in particular, are supposed to perform better and last 200,000 to 300,000 kilometers.

However, based on how you use it, it could malfunction, and the alternator might be extremely dated in the case of an older car. Keep your defenses up at all times.

Problems With The Starter

When trying to start your vehicle, your 2019 Jeep Compass wont start, but you still hear buzzing noise if your starter motor has malfunctioned and you cannot crank the engine.

As a short-term solution, there is a tried-and-true way of powering an automobile with a bad starter motor.

While your companion attempts to ignite the engine from inside the car, get a hammer and begin lightly tapping the starter.

This solution works when the starter’s internal components are jammed together, or the gears are only somewhat out of position.

It is advised that you have the starter evaluated by an experienced mechanic because it is conceivable that it is almost at the end of its lifespan.

Poor Starter Electrical Connection

The starting motor power line and its interconnections from the battery to the ignition system in Compass should be looked into after battery problems have been checked out.

If a connection has become weak or the connectors have eroded, the power source to the starter may be cut off.

Although the starter isn’t receiving any electricity from the battery, the starter solenoid’s clicking sound is being made, which is still powered because it is on a different circuit.

Lack Of Fuel

When your automobile doesn’t start, it might not have enough fuel. This is a typical issue, particularly if you have yet to refill your gas tank recently.

Refill up your vehicle fuel tank with gasoline to solve this issue. The Jeep Compass will be capable of starting once it has adequate fuel.

Your Jeep Compass won’t turn over if the gasoline system breaks down. In most cases, the pump must ensure that the vehicle’s fuel injection receives the correct amount of gasoline and fuel pressure under enough level from the container.

You should get your gasoline engine inspected if your vehicle’s engine frequently fails, is challenging to start, rattles slightly, or performs poorly. These symptoms typically occur before your fuel pump collapses.

Faulty Ignition Switch

After attempting these above solutions, there might be an issue with the ignition system or ignition switch if your 2015 Jeep Compass won’t start but has power.

To start the vehicle, you need to turn on the ignition switch. The engine will only start if it’s operating correctly. You will have to change the ignition switch to resolve this issue.

Clogged Fuel Filter

Your Jeep Compass may have trouble starting if its fuel filter is blocked. Before the gasoline reaches the cylinder, the filtration is in charge of removing debris and other pollutants.

An obstructed filter prevents the engine from starting. This happens due to the dirt impeding the fuel passage to the motor.

Your Jeep Compass’s gasoline filter doesn’t deteriorate with time like a mechanical component, but it becomes clogged with debris and other floating material. Both the gasoline flow and the filter’s conductivity decrease.

Although this doesn’t matter in the grand scheme of things, if the fuel filter becomes too dirty, the motor won’t run as efficiently.

In some cases, it can even fail to start. You could only replace the filtration system; wiping is not an option.

Worn Spark Plugs

Spark plugs ignite the gasoline in the cylinder. Wearing them out could prevent them from effectively igniting the fuel.

The result will be a non-starting engine. Damaged electrical spark plugs frequently cause a loss of horsepower or malfunctioning pistons.

If your spark plugs are broken, unconnected, or too old to work correctly, they might easily prohibit your Jeep from starting.

The 2017 Jeep Compass wont start if the spark plugs aren’t working. A flaw frequently does not affect the spark plugs themself.

Instead, the electrical system’s plug connectors loosen. You can solve the issue on the spot only when a single plug is genuinely unfastened. If a spark plug breaks, it must be changed during a repair.

Test 12V Battery

Using a multimeter to measure the correct voltage is the simplest method for testing the dead 12v battery in a Jeep Compass. A battery that has been charged up should have 12.6 volts or greater.

A voltmeter, however, will only give you a general notion of the current battery’s health. There are situations when a battery displaying more than 12.4 volts may need to be increased to provide enough power to start the motor.

The power loss of the battery cells when you attempt to start the vehicle can also be checked. Your battery lacks sufficient energy to operate the motor if the voltage goes too low, under 10 volts.

Give Your Jeep Compass A Jump Start With Jumper Cables

If your Jeep Compass won’t turn over due to a flat battery, your safest bet is to jump-start it from another car.

Before connecting the red cable to the positive electrode of the source cell, please attach it to the positive electrode of the dead battery in your Jeep Compass.

Next, attach the black cable to the negative electrode of the source battery before connecting the bare metal in the Compass’ engine compartment. Launch your Compass first, then the other vehicle. In reverse sequence, take out the cords.

Clean Battery Corrosion

You must detach the pole wires to clean the batteries on your Jeep Compass. This doesn’t involve special skills; it only takes a little focus because the order is crucial.

You can use tools to unlock a pretty tight pole clip. Although we recommend against doing so, you must be cautious not to contact any other body parts if you use a metal clamp.

Check Battery Terminals

You must look at the electrical connections to determine if dusty terminals of the battery cause the Compass starting issues. Inspect the connections for any damage by lifting the lids.

If there are no additional cracks or damage, you can get away with cleaning the battery instead of replacing it.

Inspect The Ground Connections

If your Jeep Compass not starting but has power, you should investigate the state of your Jeep Compass’s grounding connections. By doing this, you can check for any trace of rust or damage.
