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 fail.
You can remove the steering column trim using special tools to gain access to the ignition cylinder module. Consult your repair manual for guidance on how to do this in a safe manner.
1. Make sure you check the Switch
One of the most frequent ignition issues is a defective switch. It acts as a bridge between two contacts, regulating the relays' activation and deactivation. Because 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 get damaged or corroded.
A malfunctioning switch is identified by a difficulty turning the key. This could be due to a variety of things that include incorrectly inserting the key or deteriorating the mechanism over time. It's also commonplace for people to misplace their keys to their car with another's, which could lead to mechanical damage.
If the switch isn't functioning, there are a few things you can try before calling a locksmith. You'll first want to ensure that the battery is fully charged and there aren't any electrical issues within the system. It is also important to test the voltage of each component to determine if it's capable of supplying enough power. After you've completed these steps, you're ready to begin troubleshooting.
The ignition switch is simple to replace. It's connected to the ignition cylinder, which is a round module that holds everything together. To replace it, you'll need a flathead screwdriver, and something long enough to press the pin into. It could be anything from a paintbrush handle to a Kabob skewer. However, you should stay clear of anything that is brittle and break within the hole.
Remove any trim pieces that overhang the switch once you're ready to get started. After taking off the trim pieces, remove any screws holding the switch in place. Then, carefully remove it.

When the switch is in the lock position (which typically has an indicator in red) the ignition circuit is active and it is not possible to start the engine.
To determine whether the ignition switch bad or if the ignition coil itself is bad, you must conduct a quick electrical test using an Voltmeter. When the ignition switch has been running at a certain voltage, the voltmeter should read approximately 12.6, If the voltage falls below that, there is an open circuit somewhere within the system. This could be at the solenoid, Car Ignition system repair the battery or even the ignition coil itself.
Remove the electrical connector from the ignition and key replacement switch so that no other components interfere with the test. Set the voltmeter in the resistance or continuity modes and connect 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 voltmeter is "open" or does not register any voltage, you must replace the switch.
Make sure you use a new ignition key and a high-quality ignition cylinder when you replace the switch to ensure that your vehicle starts and runs correctly. When replacing the ignition switch, be careful not to hit the pins of the ignition cylinder with your tools, or they'll become stuck and your engine will not start. You'll have to take off the steering wheel and the gear selector on some vehicles to gain access to the ignition cylinder. This isn't easy and shouldn't be done unless you have an owner's manual that states that it is safe to do so. If you don't you could cause serious 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 check the cylinder. It's the part that holds your key, and is mechanically connected to the lock on the steering wheel so that a potential thief cannot control the car ignition system Repair without the key.
If your cylinder has started to wear out, you could be noticing that your key isn't able to turn. Sometimes, the pins inside the cylinder are stuck when they adjust to the shape of your key, which could cause your car not to start. The cylinder could also be loose however a tap using the small hammer from a tack can assist in releasing it. Be careful not to mix the springs, and make sure your key is correctly placed.
If you need to jiggle and move the key around before it will start, this is another indication that your cylinder is become damaged. This is a bad indication and needs to be fixed immediately, since it will only get worse with time.
To check the cylinder, you'll need to disconnect your battery, and then remove the cover from your steering wheel until you can access the ignition module. You'll then be able to 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 cylinder to a locksmith to reuse them as long as they're in good condition. After replacing the ignition switch and cylinder make sure to reconnect the wiring to secure it, then reattach all covers and panels that you took off.
4. Check the Spark Plugs
The spark plug is the final link in your ignition system chain. The engine will not start when the spark plug is broken. It could be that your car will not start at all or will run poorly. In either of these scenarios, it's likely that one of several factors are hindering or blocking the flow of electricity across spark plug gaps, which ignites the air and fuel mixture in your engine.
Be sure to wear protective tools and gloves before you begin working with your spark plugs. Spark plugs are hot and could cause serious injuries when touched with bare skin.
There may be a slight gray or brown fleck on the tip of the electrode when the spark plug is damaged. The electrode could also be covered with an opaque coating. These deposits or fouling can hinder high-voltage electrical currents from jumping across the gap between your spark plug, igniting an engine.
If you suspect that your spark plugs could be at fault, you can test them by taking them from their tube in the ignition coil. This can be done by disconnecting the coil as well as the plug wire. After that, you'll have to follow the proper procedure for your vehicle to remove the components that surround the plugs. After removing the plugs, place them on a surface that is grounded. Then begin the engine. If they're working, you should see an intense blue spark at the tip of central electrode.
If you do not see a spark, you've identified the problem. Next, you'll need to go backwards through your ignition chain and test each part until the spark plugs aren't working. Every system will wear out and eventually break and this is especially relevant to ignition systems.
