Fuel pumps can last forever. Or, they can die. Generally the main killer of fuel pumps is running the tank dry. The fuel pump is lubricated by the fuel. With no fuel the pump is severely damaged. Generally a few weeks after you ran the tank dry, the pump may fail (if it is going to).

2013 ford focus will not start. It has 75k miles on it
There are a myriad of reasons why a car won't start. Don't automatically assume it is a fuel supply issue but for the sake of argument and to answer your question, fuel pump failure is fairly rare. There are actually 2 fuel pumps on the MK3 Focus. The low pressure fuel pump is located inside the fuel tank and also incorporates the fuel filter and fuel gauge sender unit. As Elizabeth said, you can damage it by running it dry. Even if there is gas in the tank, I have also seen them stick after the car has sat for a long period of time. The gasoline can gum up in the pump and keep the impeller from spinning. This is easy to diagnose since you can hear the in tank fuel pump whirring when you first turn the ignition key. The high pressure DI fuel pump is on the driver's side of the engine bay next to the battery. All service on the fuel supply components are best left to qualified personnel. On the MK3 Focus, replacing the low pressure pump requires dropping the fuel tank which is a big job. (Some cars have access ports under the back seat but we are not so lucky on the MK3)

I don't know about the lubricating part but I've been told that the fuel cools the fuel pump.

my 2012 with 45k miles died last night. after we towed it home, the OBD scanner shows codes P0006 and P0087. It is definitely fuel related, but I cannot find any information about it online. Heck, none of the local part stores even list a fuel pump for this new of a vehicle. Where is the access location for the fuel pump? My 2003 Mazda Protégé5 hatchback had an access panel under the back seat. I have already pulled this seat, and no access panel?!

You'll have to drop the tank to get to it. Good luck. The last time I bought one it was for my '88 Bronco and cost about $350.

Did you have any symptoms prior to the failure? Rough idle, excessive vibration, prominent engine noise at speed (45-60mph). You'll have to let us know if it is quieter after you get it fixed.
