How to Fix Car Ignition Problems
The car won't start unless the switch sends an electrical signal to the starter. Normal wear and tear over time can cause the switch malfunction.
With the help of special tools, you are able to remove the trim on your steering column and access the ignition cylinder module. Refer to your repair manual for guidance on how to do this correctly.
1. Make sure you check the Switch
A defective switch is among the most common ignition issues. It acts as a bridge between two contacts, regulating when relays activate and deactivate. Since it doesn't harness the full power of devices like the starter, it's a lighter-duty component that is less likely to fail. However it's still possible for the switch to become damaged or damaged or corroded.
A bad switch is recognized by a slow time turning the key. This can be caused by many things such as improperly inserting the key, or the mechanism wearing out over time. It's also commonplace for people to misplace their car keys with someone else's, which can result in mechanical damage.
If the switch isn't working there are a few things you can try before calling a locksmith. You'll first want to ensure that the battery is fully charged and that there are no electrical issues in the system. It is also important to test the voltage of each component to determine if it's capable of supplying enough power. After you've completed these steps, you're ready to begin troubleshooting.
The ignition switch is simple to replace. It's connected to the ignition cylinder, which is a round module that holds everything together. To replace it, you'll require a flathead screwdriver and something long enough to push the pin into. This can be anything from paintbrush handles to Kabob skewer, but you should avoid using anything brittle that could break inside the hole.
Remove any trim pieces that are covering the area around the switch when you're ready to get started. After you've removed the trim pieces remove any screws that are holding the switch in position. Then carefully pull it out. Depending on the model, you might need to disconnect any cables that connect to it. Find out how to do it in the manual of your vehicle.
It is best to have the ignition switch replaced by professionals in the event that it isn't working. It is possible to replace it by disabling the steering column, which may trigger unintentional deployment of airbags if done in a wrong manner. It's best to allow your locksmith to take care of this.
2. Check the Wire
If you are unable to turn the key in the ignition or your car isn't starting, your problem could be related to any of the components in your car's ignition system. It's crucial to understand how the ignition system works to identify issues and make the necessary repairs.
The ignition switch is a low voltage multi-pole electrical switch which is operated by a key. It has four positions including off run, accessory, and "lock." If the switch is locked (which is typically marked by an red light) the ignition circuit is activated and it is inaccessible to start your car.
You can use a voltage meter to quickly test the ignition switch or coil. If the ignition switch is running, the voltmeter should show about 12.6, If the voltage drops below that, it indicates there's an open circuit in the system. This could be at the solenoid, the battery or the ignition coil itself.
Connect the electrical connector to ensure that it doesn't interfere with the test. Then, set the voltmeter to the continuity or resistance mode and put 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 show any voltage, you should replace the switch.
When changing the switch, make sure to use a brand new ignition cylinder as well as a high quality key cut to ensure that your car will start and run correctly. When replacing the switch, make sure not to hit the pins of the cylinder's ignition with your tools. In the event of a collision, they'll get stuck and the engine won't be able to run. In certain vehicles, you'll need remove the steering column and gear selector in order to access the ignition cylinder. This can be difficult and isn't recommended until you have an owner's manual that states it's safe. If you do not then you could cause irreparable damage to your steering column and the shift mechanism.
3. Check the Cylinder
If you've sifted through the wiring, battery, and ignition switch and still cannot get your car to start, it might be time to examine the cylinder. It's the component that holds your key and is connected to the lock on the steering wheel to ensure that thieves can't control the car without the key.
If your cylinder has started to wear out, you may notice that the key won't turn. The pins in the cylinder may become stuck when they adapt to the shape of your key. This could cause your vehicle to not start. The cylinder could also be shaky, but a tap with the small hammer from a tack can aid in releasing it. Be careful not to jumble the springs within and make sure that your key is properly inserted before tapping.
If you are required to jiggle and move your key before it will begin, it is a indication that your cylinder is been damaged. This is a bad sign, and it should be corrected right away, since it will only worsen over time.
To check the cylinder you must remove the cover for the steering wheel and disconnect the battery. You'll then be able to pull out the old ignition switch as well as the cylinder for ignition made of metal. If you don't have a spare ignition switch lying around, it's possible to take your original ignition switch and the cylinder to a locksmith in order to reuse them as long as they're in good condition. After replacing ignition lock repair services and cylinder, ensure that you reconnect the wiring harness, secure it in place and then reattach any covers or panels that you have removed.
4. Check the Spark Plugs
The spark plug is the final link in your ignition system chain. If it fails, the engine can't run. It could be that your car will not start at all or will run poorly. In either case, it is likely that one or more things are hindering or preventing electrical current from crossing spark plug gaps, which then ignites the mixture of fuel and air inside your engine.
Before you begin working on your spark plugs, make sure that you work on a safe surface, using gloves and tools that are protected to keep from being zapped. Spark plugs can get very hot and cause serious injuries if touched with bare hands.
You may notice a light brown or gray residue on the top of the electrode when the spark plug is defective. The electrode may also have a dark coating. These deposits, also known as fouling, may prevent high-voltage electricity from crossing the gap between the spark plug and sparking your engine.
If you suspect that your spark plugs may be the cause You can test them if you remove them from their tube inside the ignition coil. This can be done by disconnecting the coil from the plug wire and following the appropriate procedure for your vehicle to remove any components that are covering the spark plugs. After removing the plugs place them on a metal surface that is grounded and start the engine. If they are good you should be able to see a strong blue spark extending across the gap between the tip of the central electrode.
If you don't see a spark, you've identified the problem. The next step is to work back through the ignition system chain, testing each part until you can determine what is blocking the spark plugs from doing their job. Every system will wear out and eventually fail and this is especially relevant to ignition systems. But, regular maintenance can reduce the wear and tear and avoid a big headache at the worst possible moment.
