Keep getting 0601 ??? P0601 .
DTC P0601 Control Module Read Only Memory (ROM)
This has nothing to do with grounds ,You don't need a PCM diagram . You need a professional technician .

Conditions for Setting the DTC
The PCM detects more than 3 incorrect checksums.
Turn OFF the ignition switch.
Replace the PCM. Refer to the PCM Replacement .
Is the action complete?

i know industry jargon can be confusing, but lets try this. if it turns over but won't start, it could be your ''ignition module'' that sits on top of the vave cover on the motor or it might be the fuel pump or filter. make sure when you crank the engine that the key is all the way turned or it may not always make a proper contact to activate the ignition module. iv'e seen this before & had to change the ignition switch & all worked ok after that. i would need to know engine lt size to give you more details on the matter. please get back to me.

You either have bad coils or the ignition module is bad.The other thing would be dirty injectors.Depending on motor size.You can swap the coils and see if the misfire changes to different cylinders.If not the problem is not the coils.Let me know if you have any more questions.Hope this helps.Good luck.

sounds like the fuse pannel under the hood blew a master fuse

You will also need to swap the speedo cluster. thats where the anti theft module is located. After that you may still need to relearn the key switch.I will look at the wiring diagrams and get back to you on the starter circut in side the vehicle. You may have to change some other things.Talk to ya soon. Dan
