Do a coil packs on vehicles make cracking sound and smoke when you turn the ignition to start engine?

It is not normal for coil packs to make cracking sounds or produce smoke when you turn the ignition to start an engine. Coil packs are responsible for providing high voltage electricity to spark plugs, and they should operate quietly without any visible signs of damage.

If you hear cracking sounds or see smoke coming from the coil packs when you turn the ignition, it could indicate a problem. Some potential causes include:

-Faulty coil packs

-Damaged ignition wires or spark plugs

-Oil or coolant leaking onto the coil packs

If you notice any of these symptoms, it is important to have your vehicle inspected by a qualified mechanic as soon as possible to diagnose and repair the problem. Driving with faulty coil packs can cause engine misfires, reduced power, and increased fuel consumption, and it could eventually lead to more serious damage to your engine.
