If you’re having trouble starting your 2019 Jeep Cherokee, you are not alone. There are many ways to fix the issue. Check your battery terminals and the spark plugs to ensure they’re in good condition. Also, check your fuses. If all of those things are OK, you can try checking your fuel pump.
Check battery terminals
If you’ve experienced a hard time starting your Jeep Cherokee lately, check your battery terminals for corrosion. Battery terminals connect your battery to your car’s load, including the ignition and other accessories. They’re usually big metal clips marked with a positive or negative sign. If the terminals are dirty, they’ll disrupt the flow of power and interfere with the way power is delivered to your Jeep.
In case you don’t know where to find your battery, consult your owner’s manual. Some batteries are hidden beneath the floorboard, while others are in the trunk. In order to remove the battery, turn the engine off and loosen the bolt that holds the black negative battery cable.
Check spark plugs
If your Jeep Cherokee is having trouble starting, it may be time to check the spark plugs. In some cases, spark plugs can become fouled by too much fuel inside the combustion chamber. If this happens, the spark plugs will develop black and sooty carbon deposits. The only way to fix this issue is to fix whatever is causing your engine to run rich. Common causes of this problem include a dirty MAF sensor, a bad upstream O2 sensor, or a leaky injector.
A bad starter is another possible reason for your Jeep Cherokee not starting. You can take it to an auto shop to get the problem diagnosed. It is not a good idea to try to jump-start a car with a bad starter because jump-starting it will only make the problem worse. A mechanic should be able to identify the problem and replace it.
Check fuel pump
If your Jeep Cherokee is not starting, you may be having a problem with its fuel pump. Check the fuel pump connector at the back of the fuel tank. You’ll find four wires that connect to the pump. Pull off the connector and listen carefully to the fuel pump running. The fuel pump runs for approximately two seconds when the engine is off.
A faulty fuel pump can result in a number of problems. A faulty fuel pump will make the engine jerk, and engine performance may drop. A faulty fuel pump will need to be replaced. A bad fuel pump will also affect the alternator, which is directly connected to the battery. If the alternator is not working, the battery will not be able to produce the necessary electricity. This can cause problems starting and charging.
Check fuses
There are many causes of a 2019 Jeep Cherokee not starting. Some of them can be easily fixed, while others will require professional help. A blown a fuse will cost around $110 to 140, not including labor. If you can’t figure out the cause of your Jeep not starting, check the fuses.
If you notice an F19 in the fuse box, there’s a good chance that a fuse is blown. It’s easy to check with a multimeter or test light. If you don’t have either of those tools, the dealer’s service department can help you locate the faulty fuse and find out the cause of the issue.
Another common cause of a 2019 Jeep Cherokee not starting is a faulty fuel injector. This can be fixed by visiting an auto repair shop in your area. Alternatively, a faulty ignition coil pack could be the cause. Ignition coils send voltage to the spark plugs and can also cause a Jeep to not start.
Check blown fuse
If you’ve been experiencing difficulty starting your 2019 Jeep Cherokee, it’s most likely that you’ve blown a fuse. To check the fuse, simply pull the fuse holder away from the panel. If you’re not sure where to look, turn off the Jeep and make sure that the key is off. If the problem persists, you may need to consult a mechanic. A qualified mechanic will be able to check the fuse and determine whether a larger issue is at fault.
If the fuse is blown, you’ll need to replace it with an exact duplicate. Typically, these are squarish plastic fuses with two prongs. There are also cylindrical glass fuses. Make sure you replace the fuse with the same voltage as the one you’ve pulled out. Changing a fuse with a different voltage could cause further damage to the component.
