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 could cause the switch to malfunction.
Utilizing specialized tools, you can take off your steering column trim and access the ignition cylinder module. Check the repair manual to get guidance on how to do this properly.
1. Check the Switch
A malfunctioning switch is among the most common ignition issues. It controls the time when relays are activated and deactivated by acting as bridge. It is less likely to fail because it does not channel full power from devices like the starter. It is still susceptible to being damaged or corrosion-prone.
A defective switch is recognized by a slow time turning the key. This can be caused by a number of factors that include incorrectly inserting a key or the mechanism being worn out over time. It's not uncommon for people to mix keys with someone else's. This could cause mechanical damage.
If the switch isn't working there are a few things you can try before calling a locksmith. First, you must ensure that the battery is fully charged and there aren't any electrical issues in the system. You should also check the voltage of every component to ensure that they are providing enough power. Once you've done these steps, you're ready to begin troubleshooting.
Fortunately the ignition switch is simple to replace. It's connected to the ignition cylinder, a round module that holds everything together. To replace it, you'll require an flathead screwdriver as well as something long enough to push the pin into. You can use anything from a paintbrush to a kabob stick, but avoid anything that is hard as it could break into the hole.
Remove any trimming pieces that are covering the area around the switch when you're ready to go. Once you've done this remove and loosen the screws that keep the switch in place then gently pull it out. Depending on the model, you may have to cut off any cables connected to it. If you have a manual for your vehicle and model, it will show you exactly how to do this.
It's best to get the ignition switch replaced by an expert if it doesn't work. The replacement process involves turning off the steering column, which may trigger unintentional deployment of airbags if done improperly. This is why it's best to have the locksmith in your area handle this for you.
2. Check the Wire
Your car might not start if you are unable to turn the key or if it will not start. This could be due to any variety of components in the ignition system. Understanding how the ignition system functions will help you identify problems and make the correct repairs.
The ignition switch is an electric switch with multiple poles that is controlled by the key. It has four positions including off run, accessory, and "lock." If the switch is locked (which is usually marked by an red light), the ignition circuit is activated and it is inaccessible to start your vehicle.
You can use a voltmeter to quickly test the ignition switch and ignition coil. The voltmeter should be reading 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 a solenoid, the battery, or the ignition coil.
Remove 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 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 is "open" or does not detect 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 you replace the switch, make sure not to touch the pins of the cylinder's ignition with your tools. Otherwise, they'll become stuck and the engine will not run. In some vehicles, you'll have to remove the steering column and gear selector to access the ignition cylinder. This isn't easy and should not be done unless you have an owner's manual that states it's safe to do so. If you don't you could cause severe damage to your steering column and shift mechanism.
3. Check the Cylinder
If you've worked your way through the wiring, battery, and ignition switch and still can't get your car to start, it could be time to look at the cylinder. It's the part that holds your key, and is mechanically connected to the steering wheel lock to ensure that thieves can't drive the car without a key.
If your cylinder is beginning to wear out, you may be noticing that your key isn't able to turn. The pins inside the cylinder may become stuck as they adapt to the shape of your key. This can cause your car to not start. The cylinder could also be sloppy. A tap with the small tackhammer may help. Be careful not to mix up the springs and ensure that the key is properly installed.
Another indication that your cylinder is going bad is if you have to jiggle the key and try different positions before it gets started. This is a bad indication and should be corrected immediately, as it will continue to get worse as time passes.
To test the cylinder, you'll have to disconnect your battery and remove the cover around your steering wheel until you're able to 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 an extra ignition switch lying around, it's likely possible to take your original ignition switch and cylinder to a locksmith to reuse them, as long as they are in good condition. After replacing the ignition switch and cylinder, ensure that you reconnect the wiring to secure it, then reattach the panels and covers that you removed.
4. Make sure you check the Spark Plugs
The spark plug is the ignition system's last link. The engine won't run if the spark plug breaks. This could take the form of your car not running at all, or may start but run poorly. In ignition cylinder replacement near me , the cause is likely to be one of several things that hinder or prevent the flow of electricity across the spark plug gap, which ignites your engine's air and fuel mixture to run.
Be sure to use gloves and protective tools before working with your spark plugs. Spark plugs can be hot and cause serious injury when touched with bare skin.
When a spark plug goes bad, you may observe that the edge of the central electrode has a slight brown or gray residue on it. The electrode may also have a dark layer. These deposits, or fouling, can stop high-voltage electricity from jumping across the gap between the spark plug and igniting your engine.
If you suspect your spark plugs might be the cause You can test them by having them remove them from their tube inside 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 any components that are covering the spark plugs. After you have removed the plugs, place them on a surface that is grounded and start the engine. If they're good you will see a bright blue spark crossing the gap in the middle of the central electrode.
If you don't detect a spark, you've identified the problem. The next step is to go through the ignition chain, testing each part until you discover what's hindering the spark plugs from doing their job. Every system will get older and eventually break, and this is particularly applicable to ignition systems. But, regular maintenance can reduce the wear and tear and avoid a major problem at the worst time.
