How to Fix Car Ignition Problems
The car won’t begin until the switch sends an electrical signal to the starter. Normal wear and tear over time may result in the switch not functioning properly.
You can remove the steering column trim with specialized tools to access your ignition cylinder module. Consult the repair manual to get guidance on how to do this properly.
1. Check the Switch
A bad switch is among the most frequent ignition problems. It functions as bridge between two contacts, controlling the time when relays are activated and deactivated. It is less likely to fail because it does not channel full power of devices such as the starter. It is still susceptible to being damaged or damaged or corroded.
A defective switch is identified by a difficult time turning the key. This could be due to many things that include improperly inserting the key, or wearing out the mechanism over time. It’s also common for people to mistake their keys to their car with someone else’s, which can lead to mechanical damage.
If the switch isn’t working there are a few things you could try before calling a locksmith. You’ll first want to ensure that the battery is fully charged and there are no electrical issues with the system. It is also important to check the voltage of every component to ensure they are sufficient power. After you’ve completed these steps, it’s now time to begin troubleshooting.
The ignition switch is easy to replace. It’s connected to the ignition cylinder, a round module that holds everything together. To replace it, you’ll need an flathead screwdriver as well as something long enough to push the pin inside. This could be anything from paintbrush handles to kabob skewer, but you should stay clear of anything that is brittle and break inside the hole.
Remove any trim pieces that are covering the area around the switch once you’re ready to work. After removing the trim pieces, take off any screws that hold the switch in position. Then carefully take it off. Depending on the model, you might also have to unplug any wires connected to it. You can learn how to do this in the manual of your vehicle.
If the ignition switch isn’t working, it’s best to have it replaced by a professional. It is possible to replace it by turning off the steering column, which could trigger an unintentional airbag deployment if done in a wrong manner. This is why it’s often best to have your local locksmith handle this for you.
2. Verify the Wire
If you are unable to turn the key in the ignition or your car won’t start, your issue could be related to any number of components in your car’s ignition system. It’s crucial to understand how the ignition system works so that you can pinpoint problems and make the right repairs.
The ignition switch is an electric switch that has multiple poles and is controlled by the key. It has four positions including off run, accessory, and “lock.” When the switch is in the lock position (which usually has an indicator Car Ignition Barrel Replacement in red) the ignition circuit is in operation and it’s not possible to start the engine.
You can use a voltmeter quickly test the ignition switch or coil. The voltmeter should read around 12.6 volts when the ignition switch is in the running position. If the voltage is below that then there is an open circuit within the system. This could be at the solenoid, the battery or at the ignition coil itself.
Remove the electrical connector from the ignition switch so that no other components can interfere with your test. Then, set the voltmeter to the resistance or continuity mode and place one lead on one of the ignition switch’s terminals. The other lead should be connected to the positive terminal of the battery. If the voltmeter reads “open” or fails to register any voltage, you should replace the switch.
Use a brand new ignition key and a top-quality ignition cylinder when you replace the switch to ensure that your vehicle starts and runs correctly. When you replace the switch, make sure not to touch the pins of the ignition cylinder using your tools. Otherwise, they’ll get stuck and your engine won’t run. In some vehicles, you’ll have to remove the steering column and gear selector to access the ignition cylinder. This can be difficult and is not recommended unless you have an owner’s manual that states that it is safe to do so. If you do not, it is possible to cause severe damage to your steering column and the shift mechanism.
3. Check the Cylinder
If you’ve tried the battery, the wiring, and the ignition switch, but you are still unable to get your car started it could be time to examine the cylinder. The cylinder is the component which holds the key and is mechanically attached to the steering lock to ensure that thieves can’t drive the car without it.
If your cylinder has started to wear out, you might notice that the key won’t turn. Sometimes, the pins in the cylinder become stuck as they adapt to the shape of the key, which can cause your car ignition replacement not to start. Alternatively, the cylinder may be shaky however a tap using a small tack hammer can assist in releasing it. Be careful not to disturb the springs inside and ensure that your key is properly installed prior to tapping.
If you need to jiggle and move the key before it will begin, this is another indication that your cylinder is been damaged. This is a sign of trouble and should be corrected immediately, as it will continue to get worse as time passes.
To test the cylinder, you’ll need to disconnect your battery and take off the cover around your steering wheel until you can access the ignition module. Then, you’ll be able pull out the old ignition switch and the cylinder made of metal. If you don’t own an extra switch, you might be able to take the original ignition cylinder and switch to locksmiths for reuse so long as they’re in good condition. After replacing the ignition switch and cylinder, make sure to reconnect the wiring, secure it and reattach the covers and panels were removed.
4. Check the Spark Plugs
The spark plug is the last link in your ignition chain. The engine won’t start when the spark plug is broken. It could be that your car won’t start at all or will run badly. In any case, the root is likely to be one of the things that hinder or prevent electricity from crossing the spark plug gap which allows your engine’s gas and fuel mixture.
Before you begin working on your spark plugs, be sure that you are working on a safe surface, using protective gloves and tools to keep from being struck. Spark plugs can be extremely hot and can cause serious injuries if handled with hands that are not protected.
When a spark plug is bad, you may observe that the edge of the central electrode is covered with a light gray or brown residue on it. It could also have a black layer on the opposite side of the electrode. These deposits or fouling can stop high-voltage electrical current from crossing the gap between the spark plug and starting an engine.
If you suspect your spark plugs could be the culprit You could test them by remove them from their tube inside the ignition coil. You can do this by disconnecting the coil from the plug wire and following the proper procedure for your car to remove components that cover the spark plugs. After you have removed the plugs, you can place them on a grounded metal surface and crank the engine. If they are good you should see a bright blue spark crossing the gap between the tip of the central electrode.
If you don’t detect a spark, you’ve found the issue. The next step is to go through the ignition chain, testing each element until you can determine what is hindering the spark plugs from performing their job. It is important to keep in mind that all systems wear out and break down over time, and this is especially the case with ignition systems. But, regular maintenance can reduce the wear and tear and avoid a major headache at the worst time.
