In fact, any car, left sitting for a lengthy period of time will eventually encounter fuel problems. One specific problem to note would be the need for a new fuel pump.

Cars left sitting, and even daily drivers, can fall victim to fuel pump failure. Over time, debris and contaminants build up in the fuel tank.

As the fuel pump does its job picking up and supplying fuel, it also picks up debris and contaminants.

Eventually those nasty little buggers cause the pump to seize, and replacement is the long-term, sensible solution.
