Not sure if anyone else here has ran across the fuel pump issue, unfortunately I did, car would start while I was waiting for wheels to be made. Lexus picked up car and dropped me off a 350F sport loaner, and sure enough fuel pump was out. They had to order part from Japan, so didn't have my car for 3 weeks, I called Lexus Customer Care and they provided excellent customer service and was able to take care of one of my car payments as a courtesy.
Hopefully no one else has to experience this issue, but I know of quite a few RC-F's that have had this problem. Hoping it's a one time issue now that it's all back and working, I got the car back the same day wheels and tires were delivered.
