A vehicle’s ignition system is composed of several parts that work together to make your engine start smoothly. The distributor is part of the ignition system on a fuel-injected engine, and its job is to “distribute” electricity to the spark plugs. While performing maintenance on your ignition system, you should remove the distributor cap in order to clean the contacts or replace the cap. But when you put a distributor cap back on, it must be done a certain way.
Become familiar with your distributor before you take it apart. It looks like a cup with spikes on top.
