How to Fix Car Ignition Problems
The car will not start until the switch sends an electrical signal to the starter. Normal wear and tear over time may cause the switch to malfunction.
You can remove the trim on your steering column using special tools to gain access to the ignition cylinder module. Consult your repair manual to learn how to do it correctly.
1. Check the Switch
A malfunctioning switch is among the most common ignition issues. It functions as bridge between two contacts, and controls the relays' activation and deactivation. Because it isn't able to harness the full power of devices such as the starter, it's a less powerful component that is less likely to fail. The switch could still be damaged or corroded.
One sign of a bad switch is the difficulty in turning the key. This can be caused by various factors that include improperly inserting the key, or deteriorating the mechanism over time. It's also common for people to misplace their keys to their car with those of 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. First, you'll need to make sure that the battery is charged and that there are no other electrical issues within the system. Also, you should examine the voltage of each component to make sure they're sufficient power. Once you've done these steps, it's time to begin troubleshooting.
The ignition switch is easy to replace. It is connected to the ignition module, a round component that holds everything together. It's necessary to use a flathead and a piece of material that is long enough to insert the pin. This can be anything from a paintbrush handle to a kabob skewer, but you should avoid using anything brittle that could break inside the hole.
If you're ready for the work, you'll need to remove any trim pieces covering the area around the ignition switch. After this take off and loosen any screws that keep the switch in place and then gently pull it out. Depending on the model, you may need to disconnect the cables that connect to it. You can learn how to do it in the instruction manual for your vehicle.
It's best to get the ignition switch replaced by professionals if it doesn't work. Replacing it can involve turning off the steering column, which could trigger an unintentional airbag deployment if it's done improperly. It is recommended to let your local locksmith take care of this.
2. Check the Wiring
If you are unable to turn the key in the ignition or your car isn't starting, your problem could be related to any number of parts of your car's ignition system. It's important to understand how the ignition system functions to identify issues and make the appropriate 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 locked (which is typically marked by an red light), the ignition circuit is active and it is not possible to start your car.
You can use a voltmeter to quickly test the ignition switch and ignition coil. The voltmeter should read around 12.6 volts when the ignition switch is in the run position. If the voltage falls below that, it indicates there's an open circuit somewhere in the system. This could be at the battery, the solenoid or at the ignition coil itself.
Disconnect the electrical connector so that it does not interfere with the test. Then you should set the voltmeter in the continuity or resistance mode and place one lead on one of the terminals on the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltage gauge shows "open" or does not register any voltage, it's time to replace the switch.
When you're changing the switch, make sure to use a new ignition cylinder as well as a high quality key cut to ensure that your car will start and run properly. When replacing the switch, make sure not to hit the pins of the ignition cylinder using your tools. In the event of a collision, they'll get stuck and your engine won't be able to run. You'll need to take off the steering wheel and the gear selector in some vehicles to gain access to the ignition cylinder. This isn't easy and is not recommended unless you have an owner's manual that states it's safe to do so. If you don't, it is possible to cause serious damage to your steering column and shift mechanism.
3. Check the Cylinder
If you've sifted through the wiring, battery and ignition switch, but you can't get your car start, it might be time to look at the cylinder. It's the component that holds your key and is mechanically connected to the steering wheel lock so a would-be thief can't control the car without a key.
If your cylinder is beginning to wear out, you might notice that the key won't turn. The pins in the cylinder could become stuck when they adapt to your key's shape. This could cause your car to not start. The cylinder may also be sloppy. A tap using the small tackhammer may aid. Be careful not mixing up the springs and ensure that your key is properly placed.
If you need to move the key before it will begin, it is a sign that your cylinder has been damaged. This is a bad indication and should be corrected immediately, since it will only get worse over time.
To check the cylinder you'll need to take off the cover for the steering wheel and disconnect the battery. The old ignition switch should be easy to remove, as well as the cylinder made of steel. If you don't own an extra switch, you might be able take the original ignition cylinder and switch to a locksmith for reuse as long as they're in good condition. After replacing the switch and cylinder, ensure that you reconnect the wiring harness and secure it and reattach any covers or panels you removed.
4. Check the Spark Plugs
The spark plug is the final link in your ignition system chain. When it is damaged it will stop the engine from running. car ignition barrel replacement near me can take the form of your car not running at all, or may start but not run well. In either case, it's likely that one of several factors are hindering or blocking the flow of electricity across spark plug gaps, which ignites the fuel mixture and air within your engine.
Be sure to wear protective tools and gloves before working with your spark plugs. Spark plugs are hot and can cause serious injuries if you touch them with your skin.
You may notice a light gray or brown residue on the edge of the electrode if the spark plug is damaged. It could also have a black layer on the sides of the electrode. The deposits or fouling may prevent 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 taking them from their tube inside the ignition coil. This can be accomplished by disconnection of the coil and the plug wire. Then, you'll need to follow the correct procedure for your vehicle to remove the components that cover the plugs. Once you have removed the plugs, you can place them on a surface that is grounded and crank the engine. If they're good you will be able to see a strong blue spark across the gap at the tip of the central electrode.
If you don't see a spark, you've found the problem. The next step is to go backwards through the ignition chain and check each component until the spark plugs aren't functioning. It's important to remember that all systems wear down and break down with time, and this is especially the case with ignition systems. That said, routine maintenance can reduce the wear and tear and avoid a major problem at the worst moment.
