A gasoline-powered vehicle requires an ignition system to ignite fuel and turn the motor. When the ignition system is not functioning properly, your vehicle may run rough and may not pass emissions tests.
Most ignition systems consist of spark plugs, spark plug wires, a distributor and some supporting equipment.
Spark plugs are usually the first item that needs to be replaced. As spark plugs age, they may collect deposits that will hold back the flow of electricity and may cause improper ignition of fuel. Any fuel that is not burned will be expelled to the atmosphere, resulting in lower gas-mileage and an increase in emissions. The engine will lose power and the vehicle may feel sluggish while accelerating. And make sure your spark plugs are installed by an expert. Some plugs will need to be adjusted to get the best spark for your automobile.
Spark plug cables should also be replaced if they are showing signs of wear. Cables may lose their insulation as they rub against other engine parts. If there is enough insulation missing, electricity may arc to other parts of the engine before it can reach the spark plug. With the engine off, you can check insulation on the cables for any signs of roughness or holes and will be able to prevent future ignition failure.
A distributor may also need servicing, but is not normally associated with failure. If the distributor cap is cracked, contaminants may damage the distributor. In this case it is best to have the cap checked for damage and have it replaced before it causes bigger problems.
If you are driving a diesel vehicle, you do not have the same ignition components as a gasoline vehicle, but you may run into electrical problems as well. In this case, your Holland diesel repair technician should be able to offer advice for repairs.
