4 Common Reasons that Cars Struggle to Start

Express Oil Change & Tire Engineers • July 29, 2025

Few things are more frustrating than turning the key or pressing the ignition button and finding your car reluctant—or completely unable—to start. Whether it’s a slow crank, clicking noise, or no response at all, starting issues can leave you stranded and uncertain about what’s wrong. At Express Oil Change & Tire Engineers, our local mechanics are experts at diagnosing and resolving starting-related problems. Here are four common reasons that may be to blame.


Weak or Dead Battery

One of the most common reasons cars struggle to start is a weak or dead battery. Over time, batteries lose their ability to hold a charge. If the battery doesn't have enough power, you may hear a clicking sound or experience slow cranking when trying to start the engine. Corroded battery terminals or loose connections can also interfere with power delivery. 


Failing Starter Motor

The starter motor is responsible for turning over the engine when you try to start the car. If it’s faulty, the engine may not crank at all, or you may hear a grinding or clicking noise. A worn-out starter can’t generate the force needed to engage the engine. 


Fuel Delivery Issues

If the engine isn’t getting the fuel it needs to start and run, it may struggle to fire up or fail altogether. A clogged fuel filter or weak fuel pump can interfere with the fuel system. When the fuel system can’t deliver enough pressure or volume to the engine, starting becomes difficult or impossible.


Ignition System Problems

The ignition system includes spark plugs, ignition coils, and other components that create the spark necessary to ignite the fuel-air mixture. If any part of this system fails, the engine may crank but not start. Ignition problems often require a thorough inspection to identify the root cause and should be addressed promptly to avoid further engine trouble.
