How to Fix Car Ignition Problems
A car won't start unless the ignition switch sends the electrical signal to the starter motor. Normal wear and tear over time can cause the switch to malfunction.
You can remove the steering column trim with special tools to access the ignition cylinder module. Check your repair manual for instructions on how to do this in a safe manner.
1. Check the Switch
A bad switch is among the most frequent ignition problems. It functions as a bridge between two contacts, controlling the time when relays are activated and deactivated. It is less likely to fail due to the fact that it does not channel the full power from devices like the starter. It is still susceptible to being damaged or damaged or corroded.
A defective switch can be recognized by a slow time turning the key. This could be due to a variety of things that include improperly inserting the key, or the mechanism wearing out over time. It's not common to see people mix their keys up with those of others. This can cause mechanical damage.
If the switch isn't functioning there are some things you can try before calling a locksmith. First, make sure that the battery is fully charged and there are no electrical issues with the system. Also, you should test the voltage of each component to determine if they're providing enough power. After you've completed these steps, it's now time to start troubleshooting.
Luckily, the ignition switch is pretty simple to replace. It is connected to the ignition module, which is a round piece of metal that connects everything. You'll need to use an elongated flathead as well as something long enough to insert the pin. This can be anything from an artist's brush to a Kabob skewer. However, it is best to avoid any brittle material that could break within the hole.
Remove any trimming pieces that cover the area around the switch once you're ready to go. After taking off the trim pieces, remove any screws that are holding the switch in position. Then, gently pull it out. Depending on the model, you may need to disconnect any cables that connect to it. If you have a manual for your vehicle, this will tell you exactly how to do this.
If the ignition switch isn't functioning, it's best to replace it by professionals. It's difficult to replace the ignition switch without removing your steering column. This could result in an unintentional airbag deployment when you don't do it correctly. Therefore, it's best to have your locksmith take care of this for you.
2. Check the Wiring
If you're unable to turn the key in the ignition or your car won't start, your issue could be related to any of the components of your vehicle's ignition system. It is important to know how the ignition system functions 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 that are off, accessory, run and "lock." When the switch is in the lock position (which usually has the red indicator), the ignition circuit is active and it's impossible to start the engine.
You can use a voltmeter to quickly test the ignition switch and ignition coil. If car ignition replacement near me is set to run and the voltmeter is reading approximately 12.6, If the voltage drops below that, it indicates there's an open circuit in the system. It could be the solenoid, the battery, or the ignition coil.
Connect the electrical connector to ensure that it does not interfere with the test. Set the voltmeter to the continuity or resistance modes and then place one lead onto one of the terminals of the ignition switch. The other lead should go to the positive terminal of the battery. If the voltmeter reads "open" or fails to detect any voltage, you must replace the switch.
When you're changing the switch, make certain to use a new ignition cylinder and a good quality key cut to ensure that your vehicle will start and run correctly. When you replace the switch, make sure not to hit the pins of the ignition cylinder with your tools. In the event of a collision, they'll become stuck and the engine won't run. In certain vehicles, you'll need to remove the steering column and gear selector in order to access the ignition cylinder. This isn't easy and should not be done unless you have an owner's guideline that says it's safe to do so. If you do not you could cause irreparable damage to your steering column and shift mechanism.
3. Check the Cylinder
If you've gone through the battery, wiring and ignition switch, but you can't get your car start, it could be time to look at the cylinder. It's the component that holds your key and is connected to the steering wheel lock so a would-be thief can't steer the car without the key.
If your cylinder is beginning to wear out, you may notice that the key won't turn. Sometimes, the pins in the cylinder become stuck as they adapt to the shape of your key, which may cause your car to not start. The cylinder may also be sloppy. A tap with the small tackhammer may help. Be careful not mixing with the springs and make sure your key is correctly installed.
If you are required to jiggle and move the key around before it will begin, this is another indication that your cylinder is become damaged. This is a bad sign, and it must be fixed immediately as it will only get worse with time.
To check the cylinder you must remove the steering wheel cover and disconnect the battery. You should 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 an extra switch, you might be able to bring the original ignition cylinder and switch to locksmiths for reuse as long as they're in good condition. After replacing the switch and cylinder, make sure you connect the wiring harness, secure it in place and then reattach any covers or panels that you have removed.
4. Make sure you check the Spark Plugs
The spark plug is the final link in your ignition chain. If it fails, the engine can't run. This can take the form of your car not starting at all, or it could start but not run well. In either case, it is likely that one of several things are hindering or preventing electricity from jumping across spark plug gaps, which in turn ignites the fuel mixture and air within your engine.
Before you begin working on your spark plugs, make sure you're working on a safe surface and using gloves and tools that are protected to keep from being hit with. Spark plugs can be extremely hot and can cause serious injuries if touched by hands without gloves.
When a spark plug goes bad, you may be able to see that the top of the central electrode has some light brown or gray substance on it. The electrode could also have an opaque coating. The deposits or fouling may hinder high-voltage electrical currents from crossing the gap between the spark plug and starting an engine.
If you suspect that your spark plugs may be the cause you can test them by having them remove them from their tube inside the ignition coil. This can be accomplished by disconnecting the coil and the plug wire. Then, you will have to follow the proper procedure for your car to remove the components that cover the plugs. After you have removed the plugs, place them on a surface that is grounded, and begin the engine. If they're good you should see a strong blue spark extending across 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 back through the ignition chain, testing each element until you can determine what is blocking the spark plugs from performing their job. All systems will get older and eventually break, and this is particularly true for ignition systems. But, regular maintenance can to slow down the process and prevent a major headache at the worst moment.
