If the voltage is significantly lower, it may be necessary to jump-start the vehicle or replace the battery altogether.
Once the battery has been assessed, the next step is to examine the ignition switch. The ignition switch is responsible for sending power to the ignition system when the key is turned. If the switch is faulty, it may not provide the necessary power to start the engine. To test the ignition switch, turn the key to the “on” position without starting the engine and check for dashboard lights. If the lights do not illuminate, this may indicate a problem with the ignition switch. In such cases, further inspection or replacement of the switch may be required.
In addition to the ignition switch, it is crucial to inspect the fuses related to the ignition system. A blown fuse can disrupt the electrical flow necessary for starting the vehicle. Locate the fuse box, typically found under the dashboard or in the engine compartment, and check for any blown fuses. If a fuse is damaged, replacing it with a new one of the same amperage may resolve the issue. However, if the new fuse blows shortly after replacement, this could indicate a more significant electrical problem that requires professional diagnosis.
Furthermore, the ignition coil should be examined as it plays a vital role in generating the spark needed to ignite the fuel-air mixture in the engine. A malfunctioning ignition coil can prevent the engine from starting. To test the ignition coil, use a multimeter to measure its resistance. If the readings are outside the manufacturer’s specifications, replacing the ignition coil may be necessary.
Moreover, it is essential to consider the possibility of a faulty key or key fob, especially in newer Ford Explorer models equipped with advanced security features. If the vehicle does not recognize the key, it may not allow the engine to start. In such cases, using a spare key or reprogramming the key fob may resolve the issue.
Lastly, if all previous steps have been exhausted without success, it may be time to consult a professional mechanic. They possess the expertise and diagnostic tools necessary to identify complex issues within the ignition system that may not be apparent through basic troubleshooting.
