It has fuel, I hear the pump run, no spark. I have power to the coil on one wire at the connector, the other wire while turning the car over will light up the test light and the third wire is not working even when I try to see if it is a ground I get nothing on my test light.
So should the third wire be a ground? If so what do I need to check for this?
I triple checked that my timing marks were lined up before I put the cover back on, I set the tension-er back like the book said, the only wire I took off was a ground that ran over to the right side fender but I reinstalled it.

We need to know what wire does not have voltage when you are cranking the engine because depending on which one it is, will tell us what the issue is.

Basically you have 3 wires on this coil pack so it is two coils in one. So you have a Dark Green/Orange wire that is the voltage supply coming from the ASD relay. Then the other two wires, blue/gray and blue/tan coming from the PCM. These are the control wires.

Take a look at the wiring diagrams attached below for more detail.

Also, here is a video that will help with testing a coil on a vehicle:

Plus here is a guide on how to check spark as something may jump out at you to help with what is happening:
