As soon as you notice that your vehicle isn’t starting up as smoothly as usual, you’ll want to make it a priority to figure out what’s causing the problem. Otherwise, the issue could soon worsen and prevent your engine from starting at all. At Integrity Auto Care, our local mechanics are experts at diagnosing and fixing problems that cause no-start. Here’s a look at five common reasons that engines fail to start up.

Dead Battery

One of the most common reasons for a car not starting is a dead or depleted battery. If you hear a clicking sound when you turn the key or the dashboard lights are dim, there’s a good chance you have a battery problem. Common causes of dead batteries include faulty alternators, loose/corroded connections, old age, and leaving on headlights. 

Faulty Starter Motor

If you turn the key and hear a grinding noise, the starter motor may be faulty. As they age, starter motors can wear out or become damaged, preventing them from effectively turning the engine.

Fuel Issues

Running out of fuel is an obvious reason why a car won't start, but there are other fuel-related issues to consider as well. A clogged fuel filter or fuel pump failure can prevent the engine from receiving the proper amount of fuel. If you suspect that a fuel-related issue is developing, it’s best to bring it to the mechanic’s attention before it potentially leaves you stranded.

Ignition System Problems

Problems with the ignition system, such as a faulty ignition switch, can prevent the engine from starting. If you notice that the key is difficult to turn or that the engine starts intermittently, it could indicate an issue with the ignition system. 

Faulty Alternator

The alternator is responsible for charging the battery while the engine is running, so if it fails, the battery may not have enough power to start the car. Signs of a faulty alternator include dimming headlights, a dead battery, and a dashboard warning light indicating a charging system problem.
