20 Questions You Should Always Be Asking About Fix Car Ignition Before Purchasing It
How to Fix Car Ignition Problems
The car won't begin unless the switch transmits an electrical signal to the starter. Normal wear and tear over time can cause the switch to malfunction.
You can remove the steering column trim with special tools to gain access to the ignition cylinder module. Consult your repair manual to learn how to do it correctly.
1. Make sure you check the Switch
A defective switch is among the most frequent ignition problems. It acts as bridge between two contacts, and controls the time when relays are activated and deactivated. Because it doesn't transmit the full power of devices such as the starter, it's a lighter component that's less likely to fail. It is still susceptible to being damaged or damaged or corroded.
A malfunctioning switch is identified by a difficulty turning the key. This can be caused by various factors that include not inserting the key correctly or wearing out the mechanism over time. It is also common for people to misplace their keys to their car with the keys of someone else, which can lead to mechanical damage.
If the switch isn't functioning, there are a few things you can try before calling a locksmith. First, you'll want to ensure that the battery is charged and that there aren't any other electrical issues in the system. You should also examine the voltage of every component to see if they're providing enough power. After you've completed the above steps, you're ready to begin troubleshooting.
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 need an flathead screwdriver as well as something long enough to press the pin into. You can employ anything from a paintbrush to a Kabob stick, but you should 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 work. After removing the trim pieces, take off any screws that hold the switch in position. Then, gently pull it out. Depending on the model, you may need to disconnect any cables that connect to it. You can find out how to do this in the manual of your vehicle.
If fix ignition switch isn't functioning it's recommended to replace it by an expert. It is possible to replace it by disabling the steering column, which may trigger unintentional deployment of airbags if done improperly. It's best to allow your locksmith to handle this.
2. Check the Wire
If you can't turn the ignition key or your car isn't starting, your issue could be due to any number of components of your vehicle's ignition system. It's important to understand how the ignition system works to identify issues and make the necessary repairs.
The ignition switch is an electric switch with multiple poles that is operated by the key. It includes four positions "off", "accessory", "run" and the "lock". If the switch is in the lock position (which typically has an indicator in red) the ignition circuit is active and it's not possible to start the engine.
To determine whether the ignition switch is defective or if the ignition coil is defective, you will have to conduct an electrical test with an Voltmeter. If the ignition switch is set to run, the voltmeter should show about 12.6, If the voltage falls 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 on the resistance or continuity modes and place one lead onto one of the terminals on the ignition switch. The other leads should go to the positive terminal on the battery. If the voltmeter reads "open" or does not detect any voltage, you should replace the switch.
Use a new ignition key and a top-quality ignition cylinder when you replace the switch to ensure your vehicle runs and starts properly. When replacing the ignition switch, you must be careful not to hit the ignition cylinder pins with your tools, or they'll get stuck and the engine won't be able to start. In some vehicles, you'll need to remove the steering column and gear selector to get access to the ignition cylinder. This can be difficult and should not be done unless you have an owner's manual that indicates it's safe to do this. Otherwise serious damage to the steering column and shifting mechanism is likely.
3. Check the Cylinder
If you've worked your way through the battery, wiring and ignition switch but can't get your car to start, it could be time to examine the cylinder. It's the part that holds your key and is connected to the lock on the steering wheel so that a potential thief cannot control the car without keys.
If your cylinder has started to wear out, you might be noticing that your key isn't able to turn. The pins of the cylinder may become stuck when they adapt to your key's shape. This can cause your vehicle to not start. Alternatively, the cylinder may be loose however a tap using the small hammer from a tack can assist in releasing it. Be careful not to jumble the springs within and make sure that your key is correctly placed before tapping.
Another sign that your cylinder is failing is when you have to jiggle the key and try different positions before it gets started. This is a sign of trouble and should be addressed immediately, since it will continue to get worse as time passes.
To check the cylinder you must remove the cover for the steering wheel and disconnect the battery. The old ignition switch should be simple to take off, as will the cylinder for ignition made of metal. If you don't have an extra switch, you may be able to take your original ignition cylinder as well as switch to a locksmith for reuse as long as they're in good working order. After replacing the switch and cylinder, be sure to reconnect the wiring harness, secure it in place and then reattach any covers or panels you've removed.
4. Check the Spark Plugs
The spark plug is the last link in your ignition system chain. When it is damaged it will stop the engine from running. It can be that your car will not start at all or it will run poorly. In either case, the reason is likely to be one of the things that prevent or impair electricity from jumping across the spark plug gap, which ignites your engine's air and fuel mixture to start.
Be sure to wear gloves and protective tools before working with your spark plugs. Spark plugs can be very hot and could cause serious injuries if touched with bare hands.
If a spark plug goes bad, you may notice that the tip of the central electrode is covered with a light gray or brown residue on it. The electrode may also have a dark coating. The deposits or fouling may prevent high-voltage electrical current from jumping across the gap of your spark plug, igniting an engine.
If you suspect your spark plugs may be the culprit You could test them by remove the plugs from their tube inside the ignition coil. This can be done by disconnecting the coil from the plug wire, and following the proper procedure for your car to remove the components that cover the spark plugs. After removing the plugs place them on a metal surface that is grounded, and begin the engine. If they're working, you should see a bright blue spark across the gap between the tip of the central electrode.
If you don't see a spark you have found the issue. The next step is to work back through the ignition system chain, testing each part until you find out what's blocking the spark plugs from performing their job. It's important to remember that all systems wear down and break down over time, and this is especially the case with ignition systems. However, regular maintenance can help to slow down the process and prevent a major headache at the worst possible time.
