Will a coil pack keep a car from starting?
Car is not starting For vehicles that use a single ignition coil as the source of spark for all of the cylinders, a faulty coil will affect the operation of the entire engine. If the coil fails completely, it will leave the engine without spark, which will result in a no spark, no-start condition.
Where is the ignition coil located on a car?
Older vehicles have a distributor, ignition coil, and spark plug wires. Most vehicles made after the late 1990s typically have a small ignition coil that sits directly on top of each spark plug, which is known as coil-on-plug (COP) design. Regardless, the functionality is the same. When you start your engine, current flows to the ignition coil.
When do ignition coils need to be replaced?
If your vehicle’s fuel-to-oxygen mixture is either rich or lean, therefore, your ignition coils may fail prematurely. Additionally, engine heat and vibrations can cause damage to ignition coils. Nevertheless, on most vehicles can go 80,000 to 100,000 miles before requiring an ignition coil replacement.
Where are the coil packs on a Toyota?
On this Toyota, three coil packs live on the #1, #3 and #5 cylinders, and each power a plug there and on the opposite side of the engine, at #2, #4 and #6.
How are ignition coils connected to spark plugs?
The ignition coils provide the spark that fires each of the spark plugs in an engine. It is either linked to the plugs via spark plug cables, or each coil is directly connected on top of each spark plug—the latter style called a coil-on-plug (COP) or coil pack.

Is the coil pack the same as the spark plug?
The spark plug is a familiar part of a car’s ignition system and one that is routinely replaced, typically as part of a car’s major service. The same goes for the spark plug wires on cars that still use them. But the coil pack is this shadowy thing that many people wouldn’t recognize and don’t know the purpose of.

What happens to spark plugs when ignition coil goes bad?
If your car has a distributor-based ignition system, all the spark plugs will be affected by the coil going bad. If it’s a modern car with computer triggered ignition, only one plug could be affected, or two if they share the same coil.
