Vague information, the bunch of sensors? And what other codes?

P0300 is a generic misfire code, it could be loose wires , bad ground , wrong spark plugs the other two coils , the new coil is defective.

P0341 is a wiring problem and could be caused also be a bad ground

I suggest you stop guessing and throwing parts at it .
Inspect the wiring, any signs of rodent activity under the hood?
are the wires chafed near the EVAP purge valve?

any loose connections, corrosion in the connections?

Yes, very vague. This is what often happens with voice-to-text. I can't tell what you've done, why you did it, or the order that things were done.

Please slow down, use complete sentences, and punctuation.

Now , there is a level of anticipation in the first post, can this thing be saved? Will it ever run again? I get the excitement in the text.
so take a deep breath and relax. Answer some questions.

Has the voltage on the battery been checked?

Just another "One and Done" poster wasting our time.
