Usually a fuel pump is a catastrophic failure. That is, the vehicle just dies. It'll crank and crank but won't restart. But sometimes you may experience long crank times before it'll finally start due to the fuel system losing pressure once it's shut off. You may experience loss of power and/ or misfiring due to decreased pressure and volume of fuel reaching the engine from a dying fuel pump. HTH. - Jim

sometimes it can be just a fuse, or relay , relay more often than fuse. Switch with another in box! to no avail it may well be the pump.130 k miles and most will be getting weak or fail half the time. by hammering on the tank when acting up often gets it rolling for one or a few last starts
