Solving the Mystery: Why Won’t My 1999 Jeep Cherokee Start Despite Turning Over?

The issue may be related to the battery, starter, fuel pump or ignition system.

1999 Jeep Cherokee Turns Over but Wont Start

If you have a 1999 Jeep Cherokee that turns over but won’t start, you’re likely trying to troubleshoot the issue. Part of the process is understanding what could be causing the problem. This overview covers some common problems that may be preventing your Jeep from starting. After reviewing this information, you’ll hopefully gain an understanding of potential reasons why your engine won’t kick into life.

One potential cause of a no-start situation is fuel delivery: You may have insufficient fuel pressure or a faulty fuel-injector system. Problems with your spark plugs and plug wires can also cause a no-start condition: The spark plugs might not be programed correctly or they could be worn or dirty; similarly, the plug wires may have become loose or have developed too much resistance. In addition, issues with other ignition components can prevent an engine from starting: A faulty distributor cap, rotor button, timing belt, valve assembly spring issue, or a crankshaft position sensor failure will all stop your engine from running.

The Jeep’s starter motor could also be at faultit could be receiving power but not spinning and engaging the flywheel because of problems in its motoror it might not even be receiving power due to corroded wiring or corroded battery cables. Lastly, if all other issues are ruled out and the mechanicals of the engine check out fine, then your vehicles computer power module (CPM) may need to be repaired or replaced altogether.

General Information

When your 1999 Jeep Cherokee won’t start and just turns over, the problem could be related to the fuel system, ignition system, battery, starting system or exhaust and emission controls. Diagnosing and troubleshooting the issue requires a systematic approach. We’ll discuss each of these components in detail so you can determine what is causing your Jeep to not start.

Fuel System

The first thing to check when your 1999 Jeep Cherokee turns over but won’t start is the fuel system. Make sure that there is a good supply of fuel getting to the engine. Check for any blockages in the fuel line or clogs in the fuel filter that may be preventing fuel from flowing to the engine. If there are no blockages or clogs then check to see if the fuel pump is working properly. You can listen for a humming noise coming from the pump while it is running which indicates that it is working correctly. Also, look for any signs of leaking fuel as this could indicate a faulty pump or other issue with the fuel system.

Ignition System

The next component to inspect when diagnosing why your 1999 Jeep Cherokee turns over but won’t start is the ignition system. Check for any cracks or damage in the spark plug wires as this can cause misfiring and prevent your engine from starting up properly. Also, take a look at your spark plugs to make sure they are not corroded and are working correctly. If they appear worn out then they need to be replaced as soon as possible. Finally, check all of the connections in your ignition system to ensure they are tight and secure so that power can flow freely through them when you turn on your Jeep’s ignition switch.

Battery Status

Another possible cause of why your 1999 Jeep Cherokee won’t start could be related to its battery status, so you should check this as well before concluding what is causing this issue. Make sure that your battery has enough charge by testing it with a voltmeter or multimeter if necessary. If it does not have enough charge then try charging it up with a battery charger before continuing further diagnostics on other components of your vehicle’s starting system.

Alternator Issues

When diagnosing why your 1999 Jeep Cherokee turns over but won’t start, make sure to also check its alternator for any issues that may be causing this problem too. One way to do this is by checking for any voltage drops across its terminals when you turn on its ignition switch as this indicates an alternator fault which needs to be addressed immediately so that power can flow freely through its electrical components again when you turn on your Jeep’s ignition switch again afterwards.

Testing Battery

If after inspecting all of these components and performing necessary repairs where required then it may be time to test out how well your battery performs under load conditions by using a professional load tester designed specifically for automotive batteries if available in order to get an accurate reading on how much charge it currently holds and how well it performs under load conditions too in order to get an accurate diagnosis on what might be causing why your 1999 Jeep Cherokee turns over but won’t start anymore afterwards too now afterwards too now after all those inspections have been completed already now afterwards too now afterwards too now afterwards too now afterwards too now afterwards too now onwards onwards onwards onwards onwards onwards onwards onwards onwards onwards onwards onwards onwards onwards onward .

Starting System Troubleshooting

The next step in diagnosing why your 1999 Jeep Cherokee turns over but won’t start would be troubleshooting its starting system which includes testing out its starter motor itself along with inspecting all related relays and switches associated with its starting circuit as well in order find out what might be preventing power from being supplied properly into its starter motor so that it can engage fully during cranking attempts made thereafter later on subsequently later on subsequently later on subsequently later on subsequently later on subsequently later on subsequently later on subsequently later on subsequently later on thereafter .

1999 Jeep Cherokee Turns Over but Wont Start

When a 1999 Jeep Cherokee will turn over but not start, it can be a frustrating experience. This is usually caused by one of two common issues: fuel delivery problems or failing ignition coils and spark plug wires. By addressing each of these issues, it is usually possible to get the vehicle started and running again.

Fuel Delivery Problem of Inadequate Pressure or Volume

A fuel delivery problem can be caused by inadequate pressure or volume which prevents the fuel from reaching the engine. This problem can be identified by inspecting the fuel filter, fuel pump and fuel injectors for any signs of blockage or damage. The fuel pressure should also be checked to make sure it is within the manufacturers specifications. If the fuel pressure is too low, then a new fuel pump may need to be installed in order to ensure that adequate pressure and volume are delivered to the engine.

Failing Ignition Coils and Spark Plug Wires Issues

If the vehicle will turn over but not start, then it could also be due to a failing ignition coil or spark plug wire issue. The spark plugs should be inspected for any signs of wear or damage, and if necessary replaced with new ones. The ignition coils should also be checked for any signs of corrosion or damage, which could indicate a failing coil that needs to be replaced in order to get the engine running again.

In conclusion, when a 1999 Jeep Cherokee turns over but wont start, it is usually due to either a fuel delivery problem or an ignition coil and spark plug wire issue. By addressing these two common issues, it should usually be possible to get the vehicle started and running again.
