How to Fix Car Ignition Problems
The car won't begin to start until the ignition switch transmits an electrical signal to the starter motor. Over time, normal wear and tear can cause the switch to malfunction.
Utilizing special tools, you can take off the steering column trim and gain access to the ignition cylinder module. Consult the repair manual to get guidance on how to do this properly.
1. Make sure to check the Switch
A defective switch is among the most frequent ignition problems. It controls when relays are activated and deactivated by acting as bridge. It is less likely to fail due to the fact that it doesn't channel full power of devices such as the starter. The switch can still be damaged or damaged or corroded.
One indication of a defective switch is difficulty turning the key. This can be caused by many things, including incorrectly inserting the key or deteriorating the mechanism over time. It's not unusual to see people confuse their keys with keys from someone else's. This could cause mechanical damage.
Before contacting a locksmith, you can try a few things. First, you must 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 see if they're supplying adequate power. Once 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. You'll need to use a flathead and a piece of material long enough for you to press the pin in. You can make use of anything from a paintbrush to a Kabob stick, but be careful of anything that is hard as it could cause damage to the hole.
Remove any trim pieces that are covering the area around the switch when you are ready to get started. After you've removed the trim pieces take off any screws that hold the switch in place. Then, carefully take it off. Depending on the model, you might also have to unplug any wires that connect to it. If you have a manual for your vehicle and model, it will show you exactly how to do it.
If the ignition switch isn't functioning, it's best to have it replaced by an expert. car ignition replacement 's not easy to replace the ignition switch without removing the steering column. This could result in an accidental deployment of airbags when you don't do it correctly. For this reason, it's often best to have your local locksmith handle this for you.
2. Check the Wiring
If you can't turn the ignition key or your car isn't starting, your issue could be due to any of the parts of your car's ignition system. It's crucial to understand how the ignition system functions to be able to spot issues and make the necessary repairs.
The ignition switch is a low voltage multi-pole electrical switch that is operated by a key. It includes four positions "off", "accessory", "run" and the "lock". When the switch is in the lock position (which typically has an indicator in red) the ignition circuit is active and it's impossible to start the engine.
To determine whether the ignition switch is damaged or the ignition coil is bad, you need to do a quick electrical test using the help of a Voltmeter. 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 it indicates that there is an open circuit within the system. This could be at the solenoid, the battery or even the ignition coil itself.
Remove the electrical connector so that it doesn't interfere with the test. Then, set the voltmeter to the continuity or resistance mode and place one lead on one of the terminals on the ignition switch. The other lead should go to the positive terminal of the battery. If the voltage meter shows "open" or does not register any voltage then it's time to replace the switch.
Make sure you use a new ignition key and high-quality ignition cylinder when you replace the switch to ensure your vehicle runs and starts properly. Also, when replacing the ignition switch, be careful not to hit the ignition cylinder pins with your tools, or they'll get stuck and your engine won't start. In some vehicles, you'll need remove the steering column and the gear selector to access the ignition cylinder. This can be a challenge and isn't recommended until you have a vehicle's owner's manual that states it's safe. If you don't you could cause serious damage to your steering column and the shift mechanism.
3. Check the Cylinder
If you've sifted through the wiring, battery, and ignition switch but cannot get your car to start, it might be time to examine the cylinder. The cylinder is the piece that holds the key and is mechanically linked to the steering lock to ensure that burglars won't be able to drive the car without it.
You might be noticing that your key does not turn if the cylinder has worn out. The pins inside the cylinder could become stuck as they adapt to your key's shape. This can cause your vehicle to not start. The cylinder could also be loose. A tap using the tackhammer can help. Be careful not to mix with the springs and ensure that the key is properly installed.
Another indication that your cylinder is going bad is when you have to turn the key and test it in various positions before it starts. This is a bad indication and needs to be fixed immediately, as it will only get worse over time.
To examine the cylinder you'll need to unplug your battery, and then remove the cover from your steering wheel until you can access the ignition module. You should then be able to remove the old ignition switch as well as the metal ignition cylinder. 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 as they're in good working order. After replacing the ignition switch and cylinder ensure that you connect the wiring, secure it and reattach all covers and panels that you removed.
4. Check the Spark Plugs
The spark plug is the final link in your ignition chain. The engine won't run when the spark plug is broken. It can be that your car will not start at all or will run poorly. In either of these scenarios, it's likely that one or more things are preventing or impeding electrical current from crossing spark plug gaps, which then 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 avoid being struck. Spark plugs can be extremely hot and can cause serious injuries if they are handled with hands that are not protected.
If a spark plug goes bad, you might notice that the tip of the central electrode is covered with some light brown or gray substance on it. The electrode could also have a dark coating. These deposits, or corrosion, can prevent high-voltage electricity from jumping across the gap between the spark plug and igniting your engine.
If you believe that your spark plugs are at fault You can test them by taking the plugs from their tube in the ignition coil. You can do this by disconnecting the coil from the plug wire and following the correct procedure for your car to remove the components that cover the spark plugs. Once you have removed the plugs you can place them on a metal surface that is grounded and turn the engine. If they are working you should be able to see a strong blue spark at the edge of the central electrode.
If you don't see a spark you have identified the problem. The next step is to work through the ignition chain, testing each element until you discover what's hindering the spark plugs from doing their job. Every system will wear out and eventually fail, and this is particularly true for ignition systems. Regular maintenance can reduce the wear and tear and avoid an issue at the worst possible time.
