If the black and red ignition wire sparked and you replaced it but now the vehicle won't make a sound when trying to start, there are a few potential reasons for this:
Electrical damage: The spark that occurred when the wire hit something may have caused electrical damage to other components in the ignition system or the vehicle's electrical system as a whole. It's possible that the spark damaged a fuse, relay, or even the starter motor itself. In this case, further inspection and testing of the electrical system may be necessary to identify and resolve the issue.
Poor connection: When replacing the wire, it's important to ensure that the connection is properly established. If the wire is not securely connected or if there is a loose or faulty connection elsewhere in the ignition system, it can prevent the electrical current from reaching the necessary components, resulting in a lack of sound when trying to start the vehicle.
Faulty starter: It's also possible that the spark or electrical surge damaged the starter motor directly. If the starter motor is malfunctioning or if its internal components are damaged, it may not engage and turn the engine over when attempting to start the vehicle.
In any case, if you have replaced the ignition wire but the vehicle still won't make a sound when trying to start, it is recommended to have a professional mechanic inspect the ignition system and electrical components. They will be able to diagnose the specific issue and make the necessary repairs or replacements to get your vehicle running again.
