Fuel pump is electrical, may not be considered a 'powertrain' part. Do you still have the owners manual and warranty etc. books that came with the vehicle at purchase? That may have better explanation.
Dealer says could be a body controller or a key reset problem. They reset the key reset error code for this and it is running now. I will get it home tonight and see what happens when I park in the garage next to the VW and then try to start Versa in the morning. Thanks, will keep you posted. m~
