So recently I have been studying about automobiles a lot. Here is a minor part of my research on automobile problems and solutions. I have taken the references from various sites and medias and I am undoubtedly grateful to them. Automobile is getting interesting for me day by day!

Ignition Issues in Cars :


  • Car Fails to Start. One of the most obvious signs of a failing or faulty ignition switch is if the car won’t start when the key is turned. …
  • Key will not Turn. If you cannot easily turn the key in the ignition you may have a bad ignition switch.
  • Vehicle Stalls.
  • No Noise from the Starter Motor.
  • Dashboard Lights Flicker.

When the car doesn’t start, there are many problems which may be the root cause. Since the fuel injection system and car battery are linked to the ignition system, the problem can be difficult to diagnose. Here are the most common problems, which you may have to deal with.

Faulty Switch

If your ignition system doesn’t get triggered and your car won’t start, the prime culprit is often the ignition switch. The best way to deal with this problem is to replace it all together.

Dead Car Battery

Another reason why your ignition system might not work is the failure of the car battery. A dead car battery due to alternator failure might be the reason for it. Fixing the alternator and recharging the battery will solve your problem.

Worn Out Spark Plugs

Another problem is the wearing out of spark plugs. There is no way you can get them repaired. They must be replaced if you want the system to run smoothly.

Starter Motor Failure

The starter motor drives the flywheel, initially, that leads to the triggering of the car engine cycle. Hence, a starter motor failure may cause ignition problems. So, make sure that you get it checked, if your car won’t start.

Fuel Pump Failure

Another problem source is a systemic failure of the fuel pump. Because of it, adequate fuel won’t reach the injectors to start the engine cycle. Hence, you need to check out if the problems are being caused by fuel pump failure.

Bad Fuel Injectors

Another cause that may prevent engine cycle triggering is the failure of the fuel injection system. This may happen due to bad fuel injectors that are not functioning properly. You may have to go for a fuel injection service that will take care of these problems.

Coil Problems

The reason for ignition failure might be attributed to coil problems. Check out these bad ignition coil symptoms, to know if that is the reason your car won’t start.

Make sure that you include ignition maintenance in your periodic car servicing schedule. Make sure that any symptoms of possible issues are not ignored and are looked into immediately.
