Turns over but no spark, replaced PCM still no spark. Can you tell me what's up? Started disconnecting the wiring harness to check for bad wires but it seems like it's a bigger deal than what it looks like. Could the crank sensor or the cam sensor be the problem? The injectors could it's shorted out make it not run no spark. I don't know what to do next.

I would start by checking the fuses this guide can help, check to see if fuse #16 has power in the under-hood fuse panel.

Can you run the codes to see what comes up, and may I suggest a CAN scan because it sounds like the IPM is burnt out, you can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

here is a video to show you how:

Also, with the key on does one side of the fuel injector have 12 volts?

Here is how to change out the IPM in case you need it which is easy because it self-programs. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
