To check the fuel pump on any fuel injected vehicle do this.
Have a friend turn the ignition key but do not start or crank the engine you get under the vehicle, place the palm of the hand on the tank, some tanks have a protective metal shield so make sure it is the tank, have the friend turn the key several times while he counts 3 seconds 1001, 1002, 1003 and then turn key off and repeat several times.
If there is no vibration and no hum, the pump is toast!
