Depends on the vehicle. Give us more info.
If your engine has coil packs it will have one for each cyclinder. There are still a few engines that use just one coil but most use coil packs these days.
The 2000 Blazer with the 4.3 engine has one coil.
The 5.4L has 8 coil packs one on each spark plug. The 4.6L has only 2 coil block packs.
A 2001 Chrysler Town and Country has one coil pack.
One
I believe there are 8 coil packs...one sitting on top of each spark plug.
The 2004 Volvo S40 typically has four coil packs, one for each cylinder in its inline-four engine. These coil packs are responsible for igniting the fuel-air mixture in the engine's cylinders. If you're experiencing ignition issues, it may be worth checking the condition of these coil packs.
A 1997 Jeep Grand Cherokee has one ignition coil.
8 -one per cylinder
Yes, a bad coil pack can prevent your car from starting. Coil packs are essential for igniting the fuel-air mixture in the engine, and if one is malfunctioning, it can lead to misfires or a complete failure to start. However, the overall impact depends on the specific engine configuration; in some cases, the car may still start but run poorly. If you're experiencing starting issues, it's best to have the coil packs and ignition system checked.
Eight, one for each cylinder.
The Mazda Tribute typically has one coil pack for each cylinder. For the most common engine configurations, this means either four or six coil packs, depending on whether the vehicle is equipped with a four-cylinder or a V6 engine. Always refer to the specific engine model for the exact number of coil packs.
