Always tell us the exact year first! - Start with the most likely, easiest to test and cheapest to replace items.

Check all the fuses (with a DMM), Change all the most likely suspect relays: Fuel Injection, Ignition (spark) - cheap to do.

If it fails again immediately check you have ignition (15) on when the ignition switch is in the ignition position. Have someone listen to see if you get a fuel pump priming pulse when you first turn the ignition on. Only replace the Fuel Pump relay if it is known to be bad ($$$) but you can bypass it with a 30/87 bridge for test purposes.
