How to Fix Car Ignition Problems

You can remove the steering column trim using specialized tools to gain access to your 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 common ignition problems is a bad switch. It regulates the moment relays are activated, and deactivated through the use of a bridge. Since it doesn't channel the full power of devices like the starter, it's a less powerful component that is less likely to fail. However it's still possible for the switch to become damaged or damaged or corroded.

A bad switch can be identified by a difficulty turning the key. This can be caused by a variety of things, including improperly inserting the key, or deteriorating the mechanism over time. It's also commonplace for people to mistake their keys to their car with those of the keys of someone else, which can result in mechanical damage.

Before calling a locksmith, you may try a few options. First, you'll need to make sure the battery is fully charged and there aren't any other electrical issues that could be affecting the system. Also, you should examine the voltage of each component to make sure they're supplying enough power. Once you've done these steps, you're ready to start troubleshooting.

The ignition switch is simple to replace. It is connected to the ignition module, which is a round component that connects everything. You'll need to use a flathead and a piece of material long enough to insert the pin. You can use anything from a paintbrush, to a kabob stick, but avoid anything that is hard as it could break into the hole.

If you're ready for the work, you'll need to take off any trim pieces that cover the area around the ignition switch.

Understanding how the ignition system functions will help you determine the cause of the problem and make the correct repairs.

The ignition switch is a low-voltage multi-pole electrical switch that can be operated by a key. It has four positions including 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 impossible to start your car.

To determine if the ignition switch is damaged or if the ignition coil is bad, you need to do a quick electrical test using an Voltmeter. When the ignition switch has been running and the voltmeter is reading approximately 12.6, If the voltage falls below that, there is an open circuit somewhere within the system. This could be the solenoid, battery or the ignition coil.

Remove the electrical connector Fix Car Ignition so that it doesn't interfere with the test. Then, set the voltmeter to the resistance or continuity mode and place one lead on one of the ignition switch terminals. The other lead should go to the positive terminal of the battery. If the voltmeter reads "open" or does not register any voltage, it's time to replace the switch.

When replacing the switch, be certain to use a new ignition cylinder as well as a high quality key cut to ensure that your vehicle will start and run properly. Also, when replacing the ignition switch, be cautious not to touch the ignition cylinder pins with your tools, or they'll get stuck and your engine won't be able to start. You'll have to take off the steering wheel and gear selector in some vehicles to access the ignition cylinder. This can be difficult and isn't recommended until you have an owner’s manual that says it's safe. Otherwise severe damage to the steering column or shifting mechanism is likely.

3. Check the Cylinder

If you've tried the battery, the wiring, and the ignition switch, but still cannot get your car started it could be time to inspect the cylinder. It's the part that holds your key and is mechanically connected to the lock on the steering wheel so a would-be thief can't drive the car ignition switch repair without the key.

You might notice that your key will not turn if the cylinder is worn out. The pins of the cylinder could become stuck when they adapt to your key's shape. This can cause your vehicle to not start. Or, the cylinder might be shaky and a tap using the small hammer from a tack can help to free it. Just be careful not to disturb the springs in the cylinder and ensure that your key is correctly installed prior to tapping.

If you are required to jiggle and move the key before it will start, this is another indication that your cylinder is gone bad. This is a sign of trouble and should be corrected immediately, as it can only get worse over time.

To test the cylinder, you must remove the cover on the steering wheel and disconnect the battery. You should then be able pull out the old ignition switch and the cylinder made of metal. If you don't have an additional ignition switch around, it's likely possible to take your original ignition switch and the cylinder to a locksmith in order to reuse them, as long as they're in good condition. After replacing the ignition switch and cylinder ensure that you connect the wiring to secure it, then reattach the covers and panels were removed.

4. Make sure you check the Spark Plugs

The spark plug is the last link in your ignition chain. When it is damaged, the engine can't run. This could take the form of your car not starting at all, or it may start but not run well. In any case, the root is likely to be one of a few factors that block or hinder electricity from jumping across the spark plug gap, which ignites your engine's air and fuel mixture.

Before you begin working on your spark plugs, make sure that you work on a safe surface and using protective gloves and tools to prevent being struck. Spark plugs can be very hot and cause serious injuries if handled with hands that are not protected.

When a spark plug is bad, you might observe that the edge of the electrode's central portion has a light gray or brown residue on it. It could also have a black coating on the opposite side of the electrode. These deposits or a build-up of fouling could prevent high-voltage electrical current from crossing the gap of your spark plug, igniting an engine.

If you suspect that your spark plugs may be at fault, you can test them by taking the plugs from their tube in the ignition coil. This can be done by disconnecting the coil and the plug wire. After that, you'll need to follow the correct procedure for your vehicle in order to remove the components that cover the plugs. After removing the plugs place them on a surface that is grounded, and start the engine. If they're working you should be able to see a strong blue spark at the edge of the central electrode.

If you don't see any spark, you've identified the issue. The next step is to go backwards through the chain of ignition and check each component until the spark plugs aren't working. Every system will wear out and eventually break and this is especially applicable to ignition systems. Regular maintenance can slow down the process and avoid an issue in the worst case.
