Solutions To Problems With Fix Car Ignition

How to Fix G28 won't begin to start until the ignition switch is sending an electrical signal to the starter motor. Over time wear and tear could cause the switch to fail.

Using specially designed tools, you are able to remove the trim on your steering column and gain access to the ignition cylinder module. Consult your repair manual to learn how to do it right.

1. Check the Switch

A malfunctioning switch is one of the most common ignition issues. It regulates the moment relays are activated, and deactivated through the use of a bridge. Because it doesn't transmit the full power of devices such as the starter, it's a lighter-duty component that's less likely fail. It is still susceptible to being damaged or corroded.

One indication of a defective switch is the difficulty in turning the key. This can be caused by a variety of things that include incorrectly inserting the key or the mechanism wearing out over time. It's not unusual for people to mix their keys up with keys from 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, make sure that the battery is fully charged and that there are no electrical issues with the system. Also, you should check the voltage of every component to make sure they're supplying enough power. Once you've done these steps, it's time to start troubleshooting.

The ignition switch is easy to replace. It's connected to the ignition cylinder, which is a round module that connects everything. To replace it, you'll need a flathead screwdriver and something long enough to push the pin into. This can be anything from an artist's brush to a Kabob skewer. However, you should stay clear of any brittle material that could break within the hole.

Remove any trim pieces that are covering the area around the switch once you're ready to get started. After you've removed the trim pieces take off any screws that hold the switch in place. Then carefully take it off. Depending on the model, you might also have to unplug the wires that connect to it. If you have a manual for the vehicle you own it will explain exactly how to do this.

If the ignition switch isn't functioning it's recommended to replace it by a professional. It can be difficult to replace the ignition switch without removing your steering column. This could lead to an accidental airbag deployment if you do it incorrectly. It's best to leave it to your local locksmith to take care of this.

2. Verify the Wire


If you are unable to turn the key in the ignition or your car won't start, your issue could be related to any of the components in your car's ignition system. It is important to know how the ignition system works to be able to spot problems and make the right repairs.

The ignition switch is an electrical switch that has multiple poles and is controlled by the key. It includes four positions "off", "accessory", "run" and the "lock". When the switch is in the lock position (which typically has an indicator in red) the ignition circuit is active and it's impossible to start the engine.

To determine whether the ignition switch defective or if the ignition coil is faulty, you'll must conduct a quick electrical test using the help of a voltmeter. The voltmeter should be reading around 12.6 volts when the ignition switch is in the running position. If the voltage falls below that then there is an open circuit somewhere within the system. This could be at the solenoid, the battery or even the ignition coil itself.

Disconnect the electrical connector from the ignition switch so that no other components can interfere with your test. Then, set the voltmeter to the continuity or resistance mode and put one lead on one of the terminals on the ignition switch. The other lead should be connected to the positive terminal of the battery. If the voltage meter reads "open" or doesn't register any voltage, it's time to replace the switch.

Make sure you use a new ignition key and high-quality ignition cylinder when replacing the switch to ensure your vehicle is running and starts correctly. Also, when you replace the ignition switch, be careful not to strike the pins of the ignition cylinder with your tools, or they'll get stuck and the engine won't be able to start. In certain vehicles, you'll need remove the steering column and gear selector to access the ignition cylinder. This can be difficult and shouldn't be done unless you have an owner's manual that indicates it's safe to do this. If you don't, it is possible to 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, but can't get your car to start, it could be time to check the cylinder. The cylinder is the part that holds the key. It is mechanically connected to the steering lock to ensure that thieves can't drive the car without it.

You may notice that your key will not rotate if the cylinder is worn out. Sometimes, the pins in the cylinder are stuck as they adapt to the shape of the key, which may cause your car not to start. Or, the cylinder might be shaky and a tap using the tack hammer may help to free it. Be careful not to disturb the springs in the cylinder and ensure that your key is properly installed prior to tapping.

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

To examine the cylinder you'll need to unplug your battery, and then remove the cover on your steering wheel until you are able to access the ignition module. The old ignition switch should be easy to remove, as should the metal ignition cylinder. If you don't have an extra ignition switch lying around, it's possible to take your original ignition switch and the cylinder to a locksmith in order to reuse them, as long as they are in good condition. After replacing the ignition switch and cylinder, ensure that you reconnect the wiring and secure it before reattaching the covers and panels were removed.

4. Check the Spark Plugs

The spark plug is your ignition system's last link. The engine cannot start when the spark plug is broken. It could be that your car will not start at all, or it will run poorly. In either of these scenarios, it's likely that one or more things are hindering or preventing electricity from jumping across spark plug gaps, which then ignites the fuel mixture and air in your engine.

Before you begin working on your spark plugs, make sure you're working on a safe surface and using protective gloves and tools to avoid being zapped. Spark plugs are hot and can cause serious injury when touched with bare skin.

There may be a slight brown or gray residue on the edge of the electrode when the spark plug is damaged. The electrode may also have a dark layer. The deposits or fouling may stop high-voltage electrical current from crossing the gap between your spark plug, igniting an engine.

If you believe that your spark plugs could be to blame you can test them by taking them from their tube in the ignition coil. This can be done by disconnecting the coil from the plug wire and following the appropriate procedure for your car to remove the components that cover the spark plugs. After you have removed the plugs, you can place them on a grounded metal surface and then crank the engine. If they are good you should be able to see a strong blue spark extending across the gap at the tip 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 test each part until the spark plugs aren't working. It is important to keep in mind that all systems wear down and break down with time and this is particularly the case with ignition systems. But, regular maintenance can to slow down the process and avoid a major problem at the worst moment.
