There are many reasons that a car may not start.  A dead battery is one of the most common reasons. Usually, you can hear a clicking noise but the car won’t start. When a battery dies or loses its charge, it also loses its electrical power. That prevents the battery from supplying the electrical power needed to start the vehicle. The car may crank over, but still won’t start. The fuel supply to your engine will need to be checked. An engineer will check to make sure that the electrical spark is getting to your spark plugs. While an alternator is a relatively simple component containing only a few parts, it plays a critical role in any vehicle’s operation. Essentially it turns the mechanical energy of the engine’s rotating crank shaft into electricity through induction. Wires within the alternator cut through a magnetic field; this in turn induces electrical current. That current is used to power your car’s accessories, e.g. headlights. The alternator also keeps the battery fully charged, providing the power it needs to start the car this is also a common item that could need replacing. A bad ignition coil can prevent electrical power from a vehicle’s battery from reaching the engine spark plugs. If the car is silent when you turn the key in the ignition, you will need to have the battery terminal connections checked the cables may need cleaning or replacing.  A starter motor is responsible for turning a vehicle’s engine and forcing the pistons up and down. When a starter motor fails, it lacks the strength to turn the vehicle engine on. A blocked fuel filter can prevent fuel from flowing into a vehicle’s engine, and that can prevent engine combustion. A fuel pump is responsible for pumping fuel from a vehicle’s fuel tank into the engine so the spark plugs ignite the fuel and cause an engine to start and run. If the fuel pump loses its fuel pumping ability, your car won’t start. All of these possible starting issues can be checked out here at AE Services in Sutton by one of our fully qualified engineers.
