I bought a 350z recently and had it repaired for registration, we just had the reverse light switch replaced, but the car wouldn't start. And when it did start, the fuel gauge would show that the tank is almost empty despite it being filled in the morning on that day. Two days pass and the car wouldn't start. So I decided to post a thread about it here in hopes of some reassurance that this is just a common problem and has occurred to some of you, if not, I'll make sure to get it checked out at a garage.

 

Better get it checked by a Nissan tech. The fuel sender is incorporated into the fuel pump itself, so if the pump is defective, than it may not be sending an accurate signal.
