It’s important to take action when you first notice that your engine isn’t easily firing up. If you ignore the issue, it could soon worsen and prevent your engine from starting whatsoever. At Integrity Auto Care, our local mechanics are experts at identifying and fixing issues that cause no-start. 

Common Reasons that Cars Won’t Start

Oftentimes, engines fail to start due to issues with the battery/charging system. There are various reasons that car batteries die, such as: leaving on headlights, old age, parasitic draws, corroded/loose connections, and a failing alternator. Signs of alternator trouble include problems with headlights, interior electrical accessories (like power windows and the radio), and an illuminated warning light that reads ALT or GEN or comes on in the shape of a little battery.

A faulty starter is another common cause of no-start. A sign of starter trouble is that you turn the key and your dash lights come on, but you get nothing else except a clicking sound. A bad starter may also cause a grinding noise. 

Issues related to fuel supply also often prevent the engine from reliably starting. With a faulty fuel pump, gas won’t be able to correctly transit from the tank to the engine. Symptoms of a bad fuel pump include sputtering, worsening gas mileage, and a whining noise coming from the tank. A clogged fuel filter can also cause problems with getting your engine to fire up. By replacing your fuel filter about every 25,000 miles, you should be able to prevent this problem. Gunked-up fuel injectors are another fuel-related issue that can make it harder for your engine to start. Using a fuel additive can be helpful with getting rid of pollutants from injectors and intake valves.
