Hello, is the vehicle cranking over? Just not starting, or is it not cranking over at all? Have you checked the battery voltage? The battery needs to be at least 12-volts with the engine off.
Yes, I checked the battery, but before I changed the spark plugs it was fine, and I made a mistake and unplugged all the spark plugs at the same time. So, before I have my car pulled in and overspend on it, I am wondering if that may be the problem.

When you say unplugged all the spark plugs at the same time, do you mean you think you might have the firing order wrong? the spark plug wires in the incorrect places?

I'll pull up some more info for you as well. But this is the cylinder layout, the ignition module with all the coils labelled and the firing order.
Okay, I know this is tough to figure out looking from all different angles. But i think I got it right. Diagram 8 I marked the coil towers and they do go along with another diagram I found, so I think this is correct.
