What are common reasons that cars won't start?


What are common reasons that cars won't start?It's important to take action as soon as you notice that your engine is struggling to start. If the problem goes ignored, there's a good chance it will soon worsen to the point that the engine won't start at all. At Auto Check Complete Car Care, our local mechanics are highly experienced with identifying causes of no-start and then flawlessly repairing them.

Common Causes of No-Start

Insufficient fuel supply is often to blame for no-start. One cause of this is that the fuel pump isn't working properly, preventing fuel from being directed from the tank to the engine. Signs of a bad fuel pump include worsening gas mileage, sputtering, and a whining noise coming from the tank. Also, if your fuel filter is all clogged up, then your engine might not receive enough fuel to come roaring to life. By replacing your fuel filter about every 25,000 miles, you can avoid this issue. Dirty fuel injectors can also make it more difficult for your engine to fire up. You can pour a fuel additive into your tank to help with cleaning injectors and intake valves.

Problems with the battery/charging system are another common reason that engines don't start. Car batteries can die due to a variety of issues, such as old age, corroded/loose connections, parasitic draws, and forgetting to turn off your headlights. Alternator failure can also cause a battery to die. One sign of alternator trouble is an illuminated dashboard warning light that reads ALT or GEN or comes on in the shape of a little battery. Other signs of a malfunctioning alternator include issues with interior electrical accessories (like power seats and power windows) and dimming/flickering headlights.

Another common cause of no-start is a failing starter. If you try to start your car but only get a clicking sound, then you've got evidence of a bad starter. A failing starter can also cause a grinding noise.
