Ignition System Repair in Arvada, Colorado

The ignition system is responsible for starting your engine and keeping it running smoothly once it is on. When any part of this system begins to fail, it can show up as hard starts, misfires, or a vehicle that will not start at all. Because so many components work together to create the spark that ignites fuel in the engine, diagnosing ignition problems requires experience and the right diagnostic tools.

Ignition System Components

Ignition Coils Convert battery voltage into the high voltage needed to create a spark at the spark plug.

Spark Plugs Ignite the compressed air and fuel mixture inside each cylinder.

Ignition Switch Allows the driver to start the vehicle and controls power to the ignition system.

Distributor (Older Vehicles) Routes voltage to the correct spark plug at the correct time in older, non-coil-on-plug systems.

Crankshaft and Camshaft Position Sensors Provide timing information the engine control unit uses to fire the spark plugs at the right moment.

Common Ignition Problems

Engine Misfires A worn spark plug or failing ignition coil can cause one or more cylinders to misfire, leading to a rough running engine.

Hard Starting A failing ignition switch or component can make it difficult to start the vehicle, especially in cold weather.

Stalling Intermittent ignition problems can cause a vehicle to stall unexpectedly while driving.

Check Engine Light Many ignition-related issues will trigger a check engine light due to misfire codes.
