The Worst Advice We've Received On Fix Car Ignition
How to Fix Car Ignition Problems
The car won't start until the switch sends an electrical signal to the starter. Normal wear and tear over time could result in the switch not functioning properly.
With the help of special tools, you can remove your steering column trim and 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
One of the most frequently encountered ignition problems is a bad switch. It regulates the moment relays are activated, and deactivated, acting as bridge. It is less likely to fail due to the fact that it does not channel full power of devices such as the starter. The switch could still be damaged or corroded.
A malfunctioning switch is identified by a difficult time turning the key. This can be caused by many things that include not inserting the key correctly or the mechanism wearing out over time. It's not common for people to mix their keys up with someone else's. This can cause mechanical damage.
Before contacting a locksmith, you can try a few things. First, make sure that the battery is fully charged and that there are no electrical issues with the system. It is also important to test the voltage of each component to determine if it's providing enough power. Once you've completed these steps, you're ready to start troubleshooting.
The ignition switch is easy to replace. It's connected to the ignition cylinder, which is a round module that holds everything together. You'll need to use an elongated flathead as well as something long enough for you to insert the pin. This can be anything from an artist's brush to a kabob skewer, but it is best to avoid anything that is brittle and break inside the hole.
Remove any trim pieces that overhang the switch when you're ready to go. After that take off and loosen any screws that hold the switch in place and then gently remove it. Depending on the model, you might need to disconnect the cables that connect to it. If you have a manual for your vehicle, this will tell you exactly how to do this.
It's best to get the ignition switch replaced by professionals if it doesn't work. It can be difficult to replace the ignition switch, without disabling your steering column. This could lead to an accidental airbag being deployed when you don't do it correctly. Therefore, it is recommended to let your locksmith take care of this for you.
2. Check the Wiring
If you're unable to turn the ignition key or your car won't start, your issue could be related to any number of components in your car's ignition system. Understanding how the ignition system works can help you spot problems and make the appropriate repairs.
The ignition switch is a low voltage multi-pole electrical switch that is turned by the key. It includes four positions "off", "accessory", "run" and the "lock". If the switch is locked (which is usually shown by the red light) the ignition circuit is active and it is not possible to start your car.
To determine whether the ignition switch bad or the ignition coil is bad, you must conduct a quick electrical test with a Voltmeter. When the ignition switch is running at a certain voltage, the voltmeter should read approximately 12.6, If the voltage falls below that, it indicates there's an open circuit in the system. This could be at the battery, the solenoid or the ignition coil itself.
Connect the electrical connector to ensure that it does not interfere with the test. Set the voltmeter on the continuity or resistance modes and then place one lead on one of the terminals on the ignition switch. The other lead should go to the positive terminal on the battery. If the voltage meter shows "open" or does not register any voltage then it's time to replace the switch.
When changing the switch, make sure to use a brand new ignition cylinder and a good quality key cut to ensure that your vehicle will start and run correctly. When you replace the switch, ensure not to strike the pins of the ignition cylinder with your tools. Otherwise, they'll become stuck and the engine won't run. In some vehicles, you'll have to remove the steering column and the gear selector to access the ignition cylinder. This can be a challenge and should not be done unless you have an owner's manual that states it's safe to do this. If you don't you could cause irreparable damage to your steering column and the shift mechanism.
3. Check the Cylinder
If you have tried the battery, the wiring, and the ignition switch but still can't get your car started it could be time to check the cylinder. The cylinder is the part that holds the key and is mechanically attached to the steering lock to ensure that burglars won't be able to drive the car if it's not there.
You might notice that your key will not turn if the cylinder has worn out. The pins inside the cylinder can get stuck as they adapt to your key's shape. This could cause your car to not start. The cylinder could also be loose and a tap using a small tack hammer can aid in releasing it. Be careful not to mix up the springs and make sure your key is properly placed.
Another indication that your cylinder is in trouble is if you have to move the key around and test it in various positions before it gets started. This is a sign of trouble, and it must be fixed immediately, since it will only worsen over time.
To check the cylinder you will need to remove the steering wheel cover and disconnect the battery. The old ignition switch should be easy to take off, as will the cylinder made of steel. If you don't have an extra switch, you may be able 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 connect the wiring, secure it and reattach the panels and covers that you removed.
4. Check G28 Car Keys is the last link in your ignition system chain. If it fails it stops the engine from running. It can be that your car will not start at all or will run poorly. In either case, it is likely that one of several factors are hindering or blocking electricity from jumping across spark plug gaps, which then ignites the mixture of fuel and air inside your engine.
Before you begin working on your spark plugs, make sure you're working on a safe surface, using protective gloves and tools to prevent being struck. Spark plugs can be extremely hot and cause serious injuries if touched with bare hands.
When a spark plug is bad, you may notice that the tip of the central electrode has a slight brown or gray residue on it. The electrode could also have an opaque coating. These deposits, also known as fouling, may prevent high-voltage electricity from jumping across the spark plug gap and igniting your engine.
If you think that your spark plugs are at fault 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 correct procedure for your vehicle to remove the components that cover the spark plugs. After you have removed the plugs, place them on a metal surface that is grounded and start the engine. If they're working, you should see a strong blue spark crossing the gap in the middle of the central electrode.
If you don't see any spark, you have found the problem. The next step is to go back through the ignition chain, testing each part until you discover what's hindering the spark plugs from doing their job. All systems will wear out and eventually fail, and this is particularly relevant to ignition systems. However, regular maintenance can reduce the wear and tear and prevent a major headache at the worst moment.
