Can ignition coil cause an engine to not start?

Yes, a faulty ignition coil can prevent an engine from starting. The ignition coil is responsible for converting battery voltage into the high voltage needed to create a spark at the spark plugs. If the coil is malfunctioning, it may not produce the necessary spark, leading to misfires or a complete failure to start the engine. Other components may also contribute to starting issues, but a defective ignition coil is a common culprit.
