Drove car to work then wouldn't start. I have new fuel pump, new battery. Checked fuses, checked relays no problems. Checked voltage to fuel pump, 0 volts. We checked 2 engine sensors, they are within resistance limits. At a total loss as to what to check now, any ideas? Ready to drive it off a cliff.

Do you have voltage to relay? If yes turn key on and see if you have voltage to the other side of the relay for approx 3 seconds after key is turned on. If yes go to the pump repeat this test at the pump power wire if no power broken wire between pump and relay
