pressure was dropping from 80psi to 0 psi while car was seating at idle. run short test found faults for misfire on cylinder1 injector cut out and misfire at cylinder 5 and fuel delivery system.
that's their diagnose for the vehicle, and they are saying this is due to the wrong wiring between the engine and socket, and then cause the fuel delivery problem. they are saying they get the socket exchanged and replace the wire.
would the fuel delivery problem damage the other part of the vehicle? and they have the certificate for fixed the car, but i am still concern if any other problem would pop up.

Is this a new problem? It seems odd to me that suddenly there is a wiring problem (wrong wiring) if the car has always run fine in the past. Also, what do you mean by the pressure drops from 80 to 0psi? Are you referring to fuel pump pressure or oil pressure?

I just realized this is a 2012 with only 9K miles on it. This should be covered 100% under the manufacturer's warranty. Also, I find it hard that someone has already played with the wiring so it is now the incorrect wiring.
