My Jeep Wont Crank
Cranking means that a vehicles engine will turn over and eventually start. The term comes from the cranking amps that are described on batteries. These numbers will vary by battery and vehicle. If your Jeep is not starting, there are a few potential reasons that you can examine and troubleshoot yourself. Some problems will require a professional in order to do the work correctly.
Instructions
- 1
Lift the hood of the Jeep. Sometimes, the Jeep will not crank because the battery leads and cables are dirty or corroded. You may notice a creamy green and white coloration on the battery that looks like baking soda. This is actually blocking the battery from sending power to the starter. Remove the cables and polish the battery with the wire brush. Tighten them with the wrench. Try starting the Jeep.
2Jump-start the jeep with another car and your jumper cables. Remember to place red on red and black on black when you are placing the cables. Turn the key. If the engine is whirring but still not turning over, you may need a new battery.
3Take the battery out by removing the two nuts on the top of the battery. Your local auto parts store can check the battery and give you a print out stating if you need a new battery. If you need a battery replace it and install it in the Jeep. Try starting the Jeep. If it is not starting you may have another problem.
4Listen for a whirring sound. If you are getting a whirring sound you may have a grounding problem somewhere on the vehicle. Check the wire leads around the alternator. The alternator is located near the battery on the top left of the engine as you are looking at it from the front bumper. It will have a pulley and a belt around it. If there are no loose wires or frayed wires, then you may have a bad alternator that is not transferring power back to the battery.
5Listen for a clicking sound. Lack of a whirring sound, along with the presence of clicking sound, means that you have a bad starter solenoid. This will require a professional mechanic to replace.
