2003 Chevy Cavalier 2.2 Lt DOHC i tested for spark on each cylinder there is no spark i replaced the ignition coil and still no spark i ordered a ignition module but before i take it out of the packaging and install it i would like a second opinion.
First things first, is your check engine light on and have you had the codes read off of it? The problem most likely is the module but it could be other things too. It is always better to do all the diagnosis you can before just throwing parts at it. At least pick up a manual for the car that should tell you how to diagnose different parts.

you can test it but removing wires on the coil. they should have same strength as 1 and 4. if they are weaker then you have a bad coil. if nothing happens your have a bad module.
if you want put the 1,4 coil on the suspected bad tabs on the module and see if spark is same strength.that should do it. you pretty much did the right thing is swaping with what testing equipment you have to work with.
its most likely a bad module though. very common. when you test something always have someone explain how its tested and how it works.
