How to Fix Car Ignition Problems
The car won't begin to start until the ignition switch is sending an electrical signal to the starter motor. Normal wear and tear over time could cause the switch malfunction.
You can remove the steering column trim with special tools to access the ignition cylinder module. Refer to the repair manual to get guidance on how to do this properly.
1. Check the Switch
One of the most frequent ignition issues is a malfunctioning switch. It functions as a bridge between two contacts, regulating when relays activate and deactivate. It is more likely to fail since it does not channel full power of devices such as the starter. However, it's still possible for the switch to be damaged or corroded.
A malfunctioning switch is recognized by a slow time turning the key. This can be caused by various reasons such as the wrong way to insert a key, or the mechanism being worn out over time. It is also common for people to mix up their keys to their car with those of another's, which could cause mechanical damage.
Before contacting a locksmith, you might want to try a few things. First, ensure that the battery is fully charged and that there are no other electrical issues that could be affecting the system. Also, you should examine the voltage of every component to determine if it's capable of supplying enough power. Once you've completed these steps, you can begin troubleshooting.
Luckily the ignition switch is simple to replace. It's connected to the ignition cylinder, a round module that holds everything together. You'll need to use a flathead and something long enough to press the pin in. You can use anything from a paintbrush, to a kabob stick, but avoid anything that is hard as it could cause damage to the hole.
Remove any trimming pieces that are covering the area around the switch once you're ready to get started. After this take off and loosen any screws that are holding the switch in place 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 the vehicle you own and model, it will show you exactly how to do this.
It is recommended to have the ignition switch replaced by a professional when it's not working. It's difficult to replace the ignition switch without removing the steering column. This could lead to an unintentional airbag being deployed when you don't do it correctly. It is recommended to leave it to your local locksmith to take care of this.
2. Verify the Wire
If you are unable to turn the key in the ignition or your car isn't starting, your issue could be related to any of the components in your car's ignition system. It is important to know how the ignition system functions to be able to spot issues and make the necessary repairs.
The ignition switch is an electrical switch that has multiple poles and is operated by the key. It has four positions: off, accessory, run and "lock." If the switch is locked (which is usually indicated by an red light), the ignition circuit is active and it is impossible to start your car.
You can use a voltmeter quickly test the ignition switch or coil. The voltmeter should be reading around 12.6 volts when the ignition switch is in the run position. If the voltage is lower than that then there is an open circuit somewhere within the system. This could be at the battery, the solenoid or even the ignition coil itself.
Disconnect the electrical connector from the ignition switch to ensure that no other components interfere with the test. Set the voltmeter on the continuity or resistance modes and then place one lead on one of the terminals of the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltmeter shows "open" or does not register any voltage, you must replace the switch.
When changing the switch, make sure to use a new ignition cylinder and a top quality key cut to ensure that your car will run and start correctly. When you replace the switch, ensure not to strike the pins of the cylinder's ignition with your tools. Otherwise, they will get stuck and the engine won't be able to run. You'll need to take off the steering wheel as well as the gear selector in certain vehicles to get access to the ignition cylinder. This can be a challenge and isn't recommended until you have an owner’s guideline that states it's safe. Otherwise severe damage to the steering column or shifting mechanism is likely.
3. Check the Cylinder
If you've worked your way through the battery, wiring and ignition switch but cannot get your car to start, it might be time to look at the cylinder. It's the part that holds your key and is mechanically 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 could be noticing that your key isn't able to turn. Sometimes, the pins inside the cylinder become stuck when they adjust to the shape of your key, which can cause your car not to start. Alternatively, the cylinder may be loose however a tap using a small tack hammer can aid in releasing it. Be sure not to mix up the springs and ensure that the key is correctly inserted.
If visit this web page link have to jiggle and move the key before it will begin, this is another indication that your cylinder is become damaged. This is a red flag and needs to be fixed immediately, as it will only get worse over time.
To test the cylinder, you'll need to disconnect your battery and remove the cover around your steering wheel until you can access the ignition module. The old ignition switch should be easy to remove, as well as the cylinder made of steel. If you don't have a spare switch, you may be able to take your original ignition cylinder as well as switch to locksmiths for reuse as long they're in good shape. After replacing the ignition switch and cylinder, ensure that you reconnect the wiring, secure it and reattach the panels and covers that were removed.
4. Make sure you check the Spark Plugs
The spark plug is your ignition system's last link. When it is damaged, the engine can't run. It can be that your vehicle won't start at all or will run badly. In either case, the reason is likely to be one of a few things that prevent or impair electricity from crossing the spark plug gap, which ignites your engine's air and fuel mixture to start.
Make sure you wear protective tools and gloves before working with your spark plugs. Spark plugs can be hot and cause serious injuries if you touch them with your naked skin.
You may notice a light gray or brown residue on the top of the electrode if the spark plug is defective. The electrode could also be covered with an opaque coating. These deposits or fouling can stop high-voltage electrical current from crossing the gap of your spark plug and igniting an engine.
If you suspect that your spark plugs may be to blame you can test them by removing 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 vehicle to remove any components that are covering the spark plugs. After you have removed the plugs, you can place them on a grounded metal surface and then crank the engine. If they're good you will be able to see a strong blue spark crossing the gap at the tip of the central electrode.
If you do not see a spark, you've found the issue. The next step is to go through the ignition chain, testing each component until you can determine what is blocking the spark plugs from performing their job. It's important to remember that all systems wear down and break over time and this is particularly applicable to ignition systems. Regular maintenance can reduce the wear and tear and avoid a major headache at the worst possible time.
