With the wire burnt up it may have damaged a module or even wiring in trans have it scanned for codes by a trans guy it may be internal problem in trans as well due to mileage and age.

Scan for codes like I said I think you may have damaged more than you think a pro may have to do this. All because of the burnt wire.

One other thing with this if it doesn't start it may be security so try resetting that if no manual look online. Those two codes deal with evap canister purge solenoid and vent solenoid shorted out. Not sure if that will stop car from starting but should be fixed anyhow. One solenoid is on right top of engine and other under center of rear seat. I have no further suggestions or comments

You start a new post with each question not keep coming back to original writer. Check your fuel pressure with a gauge you may need an adapter autoparts rent it.
