Anytime you drive, you turn the ignition to get the engine running. But since this practice is usually second nature, it’s easy to miss warning signs that parts of the starting system—such as the alternator or starter—are in trouble. If you want to avoid an unexpected breakdown, here are five common indicators of a problem.  

5 Common Warning Signs of a Faulty Ignition

1. Failure to Start

A non-starting engine is the most common tell-tale sign of a system problem. If the engine is cranking or the dashboard lights come on, it’s possible that you simply need to jumpstart a dead battery. If no electrical components turn on, your ignition switch—where the key is inserted—may not be transferring power. However, if power is being transferred and the engine won’t turn over, you may need a new starter.

2. Misfiring

Misfiring occurs when one or more of the engine’s cylinders fails, causing the system to sputter, vibrate on idle, and jerk around during travel. Sometimes, this issue is due to a cylinder needing a new spark plug. However, if the spark plugs are intact, an electrical problem may be to blame. For instance, a weak ignition coil won’t be able to properly convert battery power to fire up all cylinders.

3. Stalling

When your vehicle stalls while driving and you haven’t run out of gas, there may be an issue with the ignition coil. Specifically, a bad coil may not be delivering a steady stream of power to the spark plugs to keep the engine running. In other instances, stalling may be linked to a bad alternator or a faulty fuel system.  

4. Hot Switch

If you notice that the ignition switch is hot when you take the keys out, there could be an electrical wiring issue that is causing overheating. In some cases, this problem may cause your vehicle to jerk. Since electrical problems only get progressively worse, get professional repairs as soon as possible.

5. Poor Fuel Economy

A bad ignition coil may not always produce physical warning signs—such as shaking or misfiring. In some situations, it may impact the way fuel is used by the engine. When this happens, your fuel economy will suffer and you may notice that you have to fill up your gas tank more than usual.
