This article is a step by step testing guide to diagnose and troubleshoot a misfire condition and/or a BAD ignition coil pack on the 99, 00, 01 Chrysler (Dodge and Plymouth) mini-vans with a 3.3L V6 engine. There are two other ignition coil pack test articles for 3.3L, 3.8L Chrysler vehicles (1990-2008) at: Chrysler 3.3L, 3.8L Index of Articles.
This first section (of this four part article) contains a lot of important information that will help you to successfully diagnose the coil pack on your Chrysler (or Dodge and Plymouth) mini-van.

What Tools Do I Need?

- A 12 Volt automotive test light.
- A multimeter (don't have a digital multimeter? Need to buy one? Click here to see my recommendations: Buying a Digital Multimeter for Automotive Diagnostic Testing).
